In the section 1, we discuss XCode configuration in order to enable the document sharing feature between computers and iPad via iTunes. In the section 2 and 3, we’ll be creating 2 applications to discuss about the new Document Support features between iPad Apps. Our Applications will be called “DocumentOpener” and “DocumentReader”. DocumentOpener will be simply redirect files to be opened in appropriate applications. DocumentReader will accept files that DocumentOpener redirected and display them.

1. File Sharing with iTunes

First, create a OS 3.2 view based project in XCode. We’ll add the File-Sharing support to this application first. Adding File-Sharing support is as simple as adding a new key in info.plist file.

Open your info.plist file and add the following key under Information Property List: “UIFileSharingEnabled“.

Right Click on the Value Type column and set it as boolean type.

Install the application on iPad and connect it to iTunes.

Go to the application in iTunes, and you should now be able to see /Document directory. You can now move around your files between your application and your computer through iTunes. Sometimes you may not see the /Document directory when you connect your iPad to iTunes. When this happens, you just simply need to disconnect and reconnect your iPad to iTunes again.

2. Opening a document in other applications

Next open up your xib file and add a toolbar and Bar Action Bar Button to your view.

In your Viewcontroller.h file add the following code:

@interface ipadDocOpenerViewController : UIViewController {
IBOutlet UIBarButtonItem *mItem;
UIDocumentInteractionController *controller;
 
}

You need to retain the UIDocumentInteractionController or it won’t work properly.

UIDocumentInteractionController can have 4 types of menu:

1. Quick View
2. Open In “the most recent or most view application”
3. Open In
4. Action

2.1 Open In …

OpenIn menu will allow user to select from a list of application that can support the target document. In our viewController.h file we decleared a method:

-(IBAction) clickOpen:(id)sender)

Let’s implement the method in our viewcontroller.m

-(IBAction) clickOpen:(id)sender {
NSString *fileToOpen = [[NSBundle mainBundle] pathForResource:@"License"  ofType:@"pdf"];
self.controller = [UIDocumentInteractionController  interactionControllerWithURL:[NSURL fileURLWithPath:fileToOpen]];
self.controller.delegate = self;
 
CGRect navRect = self.navigationController.navigationBar.frame;
navRect.size = CGSizeMake(1500.0f, 40.0f);
[self.controller presentOptionsMenuFromRect:navRect inView:self.view  animated:YES];
 
}

First, we create the NSString that stored the URL.Next we initialize our UIDocumentINteractionConroller with that URL.  In the next step, we create a rectangle to display our menu, and we present our DocumentController menu inside our main view. Do not forget to make appropriate connection in interface builder to our clickOpen method and UIBarButtonItem.

Here is our DocumentOpener in action:

2.2 Quick View

iPhone OS 3.2 support in document open preview option for supported document type. What this mean is that even if your application doesn’t support the file type of a document, you can still open the document inside your application if the file type is  supported by iPhone OS (Example pdf, jpeg).  Yes, you can open a pdf file in any application by using quick view feature. Let’s add the quick view to our DocumentOpener menu.

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller
{
return self;
}
 
- (UIView *)documentInteractionControllerViewForPreview:(UIDocumentInteractionController *)controller
{
return self.view;
}
 
- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController *)controller
{
return self.view.frame;
}

QuickView In Action:

This conclude the first part of our tutorial. In our next section, we’ll create an application that act as document server. We’ll discuss about how to open the documents coming from the DocumentOpener application.

3. Accepting Incoming Documents (Document Reader)

Let’s create a iPhone OS 3.2 view based application called “DocumentReader“. To accept incoming documents, first we need to declare which document types that our application can support. Second we need to get the URL of the incoming file.

3.1 Declearing support document types

Open up your info.plist file. For our application, we’ll add PDF support, so our other applications can see our DocumentReader in their OpenIn menu.

UTI (Uniform Type Identifiers) make it easier to declare document types in iPhone OS environment. For more bout UTI, please visit the following link:

http://developer.apple.com/macosx/uniformtypeidentifiers.html

You can add multiple document support types in your info.plist file. As long as they are properly declare, other apps can easily pick up your application by this key automatically.

3.2 Reading the URL of an incoming document

To read the URL of a document coming from other application, all you need to do is implement “applicationDidFinishLaunching” and “application didFinishLaunchingWithOptions” methods.

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
 
[window addSubview:viewController.view];
[window makeKeyAndVisible];
}
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self applicationDidFinishLaunching:application];
 
if (launchOptions && [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey])
{
printf("Launch options:\n");
CFShow(launchOptions);
 
NSString *filePath = [NSString stringWithFormat:@"%@", (NSURL*)[launchOptions objectForKey:UIApplicationLaunchOptionsURLKey]];
viewController.mLabel.text = filePath;
[viewController.mWebView loadRequest:[NSURLRequest requestWithURL:(NSURL*)[launchOptions objectForKey:UIApplicationLaunchOptionsURLKey]]];
 
}
 
return YES;
}

In our code, we simply read incoming URL and display the file in a simple UIWebView. This conclude our tutorial on File-Sharing and Document Support. Happy Coding.

Hiro demonstrated our medical apps.

A picture with Dr. Maki Sugimoto who is one of most important speaker in this event.

The main criteria of this post is to help you add a cool effect called the “cover flow/open flow” effect to any of your iphone apps. This is cool in two ways actually. One it adds animation kind of effect to your app and the other, its very easy to build too.

I got to learn about this effect when I was working on my “pianos” app where in i’ll have bunch of animals to select which would be displayed as a menu using this “cover flow” effect. Once a particular animal is selected your piano view for that animal comes up. My piano app will be out soon and you can check that out. The source for this post is the link displayed below.

“http://fajkowski.com/blog/2009/08/02/openflow-a-coverflow-api-replacement-for-the-iphone/”

Based on his post I have simplified things further. He uses “flicker API” for the images in his “cover flow”  but in my version I would just use my own library of images so that this post would target the beginners. To begin with we should work with Photoshop a bit to generate your images. If your not acquainted with photoshop, never mind not a problem at all. This particular task with the photoshop just wants you to scale the  images you use in your library to size “225 * 225″ applying “Free Transformation”. That’s all what you got to do. Once you got your images then your ready to go.

Creating the project

Firstly Create a new “view based”  project with project name like “CoverFlow”.

Once you create a new project you would arrive at a screen shown below with predefined classes already generated for you.

Add the OpenFlow source code to your project

You could get the “OpenFlow” source code from “http://apparentlogic.com/openflow“. Add the Openflow library to your project.

Adding OpenFlow source code to the project.

Add QuartzCore and CoreGraphics frameworks to your project.

Adding frameworks

Add both the frameworks form the “Existing Frameworks..” .

Implementing the “CoverFlowViewController.h” class.

-Import “AFOpenFlowView.h” into your CoverFlowVieController.h class.

-Then, you will have to implement two protocols AFOpenFlowViewDelegate and AFOpenFlowViewDataSource.

-The only member of .h class would be a queue to hold all the images needed for the cover flow.

Once you are done with all 3 steps, your source code would be as shown below.

//  CoverFlowViewController.h
//  CoverFlow
//
//  Created by Avinash on 4/7/10.
//  Copyright Apple Inc 2010. All rights reserved.
//
 
#import
#import "AFOpenFlowView.h"
 
@interface CoverFlowViewController : UIViewController  {
 
// Queue to hold the cover flow images
 
	NSOperationQueue *loadImagesOperationQueue;
 
}
 
@end

Implementing the “CoverFlowViewController.m” class.

Open the CoverFlowViewController.m class and you will see many methods already generated and commented out.

As we  want this effect to occur as soon as our view is loaded, we start writing our code under the method -(void)viewDidLoad{

}

Just uncomment the method and start writing the code.

Lets see how we implement this class

-Load the images into the queue

- (void)viewDidLoad {
    [super viewDidLoad];
 
	// loading images into the queue
 
	loadImagesOperationQueue = [[NSOperationQueue alloc] init];
 
	NSString *imageName;
	for (int i=0; i < 10; i++) {
		imageName = [[NSString alloc] initWithFormat:@"cover_%d.jpg", i];
		[(AFOpenFlowView *)self.view setImage:[UIImage imageNamed:imageName] forIndex:i];
		[imageName release];
		NSLog(@"%d is the index",i);
 
	}
	[(AFOpenFlowView *)self.view setNumberOfImages:10];
 
}

-We implement two delegate protocols one to set the default image for the cover flow and the other to tell which image has bee selected.

//delegate protocols
 
// delegate protocol to tell which image is selected
- (void)openFlowView:(AFOpenFlowView *)openFlowView selectionDidChange:(int)index{
 
	NSLog(@"%d is selected",index);
 
}
 
// setting the image 1 as the default pic
- (UIImage *)defaultImage{
 
	return [UIImage imageNamed:@"cover_1.jpg"];
}
 
CoverFlow@end

Once both your classes are implemented you need your Image library to display the images in the Cover Flow effect. Just drag and drop your set of images folder under the Resources tab of your project

Adding images library to the project

Once you have implemented both the classes and your images library is ready you will be just left out with final step, modifying the interface builder i.e, the .xib file.

You will find this .xib file under the  Resources tab in the project. Double click this .xib file and it opens up the “interface builder”.

Resources-iphone –> CoverflowViewController.xib

Once you open this file the Interface Builder would present you with  3 to 4 separate windows like Library, Identity Inspector, View, Reveal in document window.

If they do not open up automatically, nothing to worry, you can open it up manually and you find all these windows in the Tools tab of the Interface Builder. Once you open up the CoverFlowViewController.xib window you will find attributes like Files owner, First Responder, Open Flow View.

As you can see the type of this Open Flow View attribute will be set to UIView.

But as we are creating a Open Flow View instead of the regular UIView its identity should be changed to AFOpenFlowView.

To do this select the Open Flow View attribute in the .xib window and in the Identity Inspector window go to the tab “i” (identity) the right corner tab. Change the class UIView to AFOpenFlowView as shown below.

changing the View Identity

Once you are done with this final step  the stage is set and you are ready to go. Save and Run this project in the iphone simulator and you must be able to see the Cover Flow effect as shown in the  screen shot below.

Cover Flow Effect

And there you go, you have just added the cool  Cover FLow Effect to your apps in minutes. But it took me much longer time to complete this post.

Hope you liked this post and feel free to add any comment or any suggestions.

I have been creating an App using TableView with SQLite Manager….As a Beginner Like many others I too visited many sites in search of understanding about tableviews and how to Integrate it with Database….Here I am giving you all a detailed explanation of about TableViews and Database….let us look at it….

AIM OF THE Project: Here our Aim is Afterwhen launching into the Application you get list of Animals names Displayed and when you click on those animal names you get details of those animals in the next view.

So Initially for developing any project you must have:

• Database —- At first we must have our database ready in our Hand in order to make our lifes easy for using that in our Application.

Now let us look at how to create Database using SQLite Manager….

Foreign key (Missing):

SQlite Manager: Is easy to use and create database but the only issue with it is THERE IS NO FOREIGN KEY OPTION….Foreign keys Constraint is Missing in SQLite Manager.

SQLite3: In the NEW VERSION of SQLite 3.6.19 and latest versions they have added the Foreign key concepts in them. But remember SQLITE3 is Different from SQLite Manager.

Download SQLite Manager Add-on from FireFox and then Open Firefox > Tools(Menu) > SQLite Manager

Then Menu (In SQLite Manager)> (click) NewDatabase > SampleDB( Name of Database )

Then select the database from the Directory (option on the top, Go to your Folder) > SampleDB(select your Database)

After that From the Menu on the Top in SQLite Manager you will find Different options for Creating Table, Editing Table etc….so from that Click Create Table and then create tables after that Insert Data into those using “Insert Into” Statement into those tables….

Inserting data into those tables We Must go to EXECUTE SQL (Option in SQLite Manager ) > Write Queary for Inserting data into the table > RunSQL

In this App for SampleDB, I wrote two Tables called:

1) Animals   2) Descsription —- here is how the database look like….

So We have completed Creating the DataBase for our Project,now we will be jumping into X-Code for Developing the App….

TableViews:

In Table Views the most important thing we need to keep track is switching between the Views….In my Project I have two views

1) For the First View I am inserting the data Manually

2) For the Second View I am Inserting data into tableview from the DataBase.

• so Initially Go to X-Code > iPhoneOS > Navigational-based Applications > SampleTableViewApp (Name of The App) > Choose

Now you see the Couple of Files Generated for us….

Here you see 1) RootViewController.h 2) RootViewController.m 3) SampleTableViewAppDeligate.h 4) SampleTableViewAppDeligate.m 5) RootViewController.xib

These are the Files generated by X-Code and you can see those files in Classes Folder and Resources Folder.

Adding SQLite3 lib file: Before starting the code we have to Add the SQLite3 Library into the Framework in the Application.

(right Click) Frameworks > Add File > Add Existing Frameworks > LibSqlite3.0.dylib > Add

FMDB Wrapper: I am using FMDB Wrapper as an alternative for SQLite3 as it has easy way of  steps for accessing the DataBase. You can download this wrapper from Google. After downloading  JUST DRAG THE FMDB FOLDER INTO YOUR APPLICATION.

Adding Database: Next Step is Add Database file to your Application

Go to your DataBase folder where you stored your SampleDB > Drag it in to your App ( You can store it in anywhere )

Coding: Let US Start coding the App…..so

The Next Step is We have Got the Files above and now Go to:

(right click on) SampleTableViewApp > Add > NewFile  > UIViewController SubClass > Next > ElephantViewController.m (Name of File) > Click Checkbox to add .h Files as shown in Figure.

In The Same way Add the LionViewController file….

Don’t get confused with the RootViewController,Deligate file, ElephantViewControllerfiles, LionViewController…. I will Explain you all those….

RootViewController: It is the First View of our App

ElephantViewController, LionViewController: These are the Detailed View of the items which are displayed in the first view

Deligete Files: This is the File which have all the details of deligate methods of TableView.

So now we have our RootView files and the DetailedView file of the Root View….Now we will code our RootViewController File:

Steps:

1)   RootViewController.h : Import “AnimalViewController” , then Create An Mutable Array for storing the Elements. Here is the code below:

#import <UIKit/UILit.h>
#import "ElephantViewController.h"
#import "LionViewController.h"
 
@interface RootViewController : UITableViewController
{
 
NSMutableArray *mAnimal;
 
}
 
@end

2) Go to RootViewController.m: then add the below code in View Did Load Function:

Here we are adding objects in the Array and Setting Title to the First View of The App….Every thing is explained in the Code:

- (void)viewDidLoad
{
    [super viewDidLoad];
 
	/* Here we have allocated some memory to the Array object so we have to release it in Dealloc Function */
 
	mAnimal = [[NSMutableArray alloc] init]; 
 
	/* Next Step is Adding Objects to the Array*/
 
	[mAnimal addObject:@"Elephant"];
	[mAnimal addObject:@"Lion"];
 
	/* Setting Title to the First View */
 
	[self setTitle:@"Quote Category"];
 
}

Modifying TableView Deligate Methods:

3) In this step we have to Modify the Deligate Methods of the Tableview according to our App Requirements:
These can be found in the Bottom after the ” #pragma mark Table view methods” Line. so Add the Below Code in those Methods:

Here the First Method we have to change is “NumberOfRowsInSection” by default it is “0″ but We want our Rows to be Displayed as the number of elements in the Array so Update your Code as shown below:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [mAnimal count];
}

4) In this step we can Configure the cells in the TableView by changing this Method “cellForRowAtIndexPath”
we can set the Accessory type like” > ” as shown in the iPhone or iPod:

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
 
	/* These are the Default Methods we don't need to configure them */
 
    static NSString *CellIdentifier = @"Cell";
 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
        /* Configure the cell.
	   We have to start configuring cells from here
	 */
 
          [cell setText:[[qCategoriesList objectAtIndex:indexPath.row] retain]];
 
	/* set the Accessory Type to our Cells like ">"*/
 
	 [cell setAccessoryType:UITableViewCellAccessoryDetailDisclosureButton];
 
    return cell;
}

5) Next Most Important step is “Pushing the First View to Second View” for this uncomment the “DidSelectRow” and do the following code:

// Override to support row selection in the table view.
 
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
 
	/* all the Methods are already given in this Function, We just need to change them according to our Requirements
	   If we Select Elephant then the View has to Push into another View giving details abuot the Elephant */
 
	// Elephant View
 
	if([[mAnimal objectAtIndex:indexPath.row] isEqual:@"Elephat"])
	{
		ElephantViewController *mEle = [[ElephantViewController alloc] initWithNibName:@"ElephantViewController" bundle:nil];
		//Setting title to the TableView
		[mEle setTitle:@"Elephant Details"];
		//Pushing the View from RootView to ElephantView
		[self.navigationController pushViewController:mEle animated:YES];
		//releasing the Allocated Object
		[mEle release];
	}
 
	// Lion View
 
	if([[mAnimal objectAtIndex:indexPath.row] isEqual:@"Lion"])
	{
		LionViewController *mLion = [[LionViewController alloc] initWithNibName:@"LionViewController" bundle:nil];
 
		//Setting title to the TableView
		[mLion setTitle:@"Lion Details"];		
 
		//Pushing the View from RootView to ElephantView
		[self.navigationController pushViewController:mLion animated:YES];
 
		//releasing the Allocated Object
		[mLion release];
	}
/* There ends the Pushing of our view now we have to code in our detailed views of Elephant and Lion in order to display data about them----we are displaying this data from the Database */
 
        // Navigation logic may go here -- for example, create and push another view controller.
	// AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil];
	// [self.navigationController pushViewController:anotherViewController animated:YES];
	// [anotherViewController release];
}

Now we have to Code Our Detailed Views and Display data in them…We first Code our ElephantViewController

6) Now As we have created our “ElephatViewController” as a SubClass of UIViewController we need to Change that to UITableViewController Class
i:e “ElephantTableViewController” as we want to display data in a TableView in ElephantViewController. Here is the Code of that:

/* We have to import the FMDB Headers in our file as we have to use its queary methods for accessing the DB*/
#import
#import "FMDatabase.h"
#import "FMResultSet.h"
 
/*
It is Like this
@interface ElephantViewController : UIViewController
Now we are going to change it like this:
*/
@interface ElephantViewController : UITableViewController
{
	// We have to Create an Array in order to Hold the Data coming from the DataBase
	NSMutableArray *aElephant;
	//NSString object is used to hold the elements retrived from the database
	NSString *eleData;
}
@property (nonatomic,retain) NSString* eleData;
@end

7) Now as we did the .H file we have to implement the database connection and get the results form the DB
here how it goes: now go to ElephantViewController.m File then do this code….

#import "ElephantViewController.h"
 
@implementation ElephantViewController
 
@synthesize eleData;
 
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
 
- (void)viewDidLoad
{
    [super viewDidLoad];
 
	/* Now here we have to write the code from the database to display the details */
 
	aElephant = [[NSMutableArray alloc] init];
 
	/*
	  Here we have to set the path
	  We are creating the path for the datbase file in order to access
	*/
 
	NSString *path  = [[NSBundle mainBundle] pathForResource:@"SampleDB" ofType:@"sqlite"];
 
	/* FMDatabase here is used to take the database path */
 
	FMDatabase *db  = [[FMDatabase alloc] initWithPath:path];
 
	/* Here we are opening the datase in order to access it */
 
	[db open];
 
	/*
	 Then the next step here is taking the datbase result using the sqlqueary and then carrying that result into the resultset object
	 Resultset for Elephant: select * from Description where a_id=1; here description is the table, a_id is the id of Elephant it is
	 the primary key in animals table
	 */
 
	FMResultSet *fResult= [db executeQuery:@"SELECT * FROM description WHERE a_id=1"];
 
	/* Now we have to take these results in to a loop and then repeteadly loop it in order to get all the data in a   our Array Object */
 
	while([fResult next])
	{
		/* taking results from database to a string "eleData" */
		eleData = [fResult stringForColumn:@"desc"];
		/* adding data from the string object to Array */
		[aElephant addObject:eleData];
		/* Checking weather data has come or not */
		NSLog(@"The data is %@=",eleData);
	}
	/* Closing the Database */
	[db close];
}

And now we got our data form the Database and stored it in the array Element

In this Step as we got our data we have to now display that data in the table view of ElephantViewController.
For that we need deligate methods of TableView….Just Go to UITableView and copy the methods from there under the” #pragma mark Table view methods”….

So now we only copy the required methods of Deligate….methods with code are shown below, we don’t need to copy the “DidSelectRow”
as we are not pushing this view to another view…we are just displaying the data here…. copy deligate methods above the dealloc():

/* UITABLEVIEW Deligate Methods */
 
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}
 
// Customize the number of rows in the table view.
 
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [aElephant count];
}
 
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
 
    static NSString *CellIdentifier = @"Cell";
 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
         // Configure the cell.
        //We are configuring my cells in table view
 
        NSString *eData = [aElephant objectAtIndex:indexPath.row];
	cell.textLabel.text  = eData;
 
    return cell;
}

So Finally we did the Code part now we have to do the Interface builder for the ElephantViewController….
Remember in the above RootViewController we did not do any interface builder why because by default the TableView is added to it….as initially we selected
“Navigation based Application”….

For adding the TableView in the ElephantViewController (click)ElephantViewController.xib > then drop TableView on to the View Window.
Important Info:
In the Connection we have to connect the datasource and deligate to the FilesOwner in the Interface Builder.

9) We have completed the Detailed View of ElephantViewController now we have to do the LionViewController:
Repeat the same code for LionView Controller after doing that Save the files and Interface Builder….

X-Code > Build > Go

This is the Final Result of our Application:

RootViewController View

Detailed View of ElephantViewController

Detailed View of LionViewController

And So Thus our Project gets Succeeded….Hope this article helps you….

Since ObjectGraph Research Lab was funded for $1 million in the beginning of this year, we explored various fields in computational theory, such as distributed computing, brain science, and computational physics.

Today, we are glad to announce that we start collaborating with a non-profit reseach organization, USODESU(The United Science Organization and Domestic Environment Science Union). Dr. Sríníváská Gávínskí, Ph.D who has been researched Digestive System of Mobile Computation for 25 years and Kíchíego Tákévuruchí who is our first research fellow at ObjectGraph Research Lab ™ collaborated to publish an article, “Estimating the economic damages from April 1st Activities in mobile markets and Computational Economics Theory”. This scholar type of article was approved and printed by Journal of Environmental Virtual Economics.

Our main focus is to research overwhelmed network bandwidth of major mobile career by false news on April 1st and creating pseudo mobile software. From the conclusion, we estimated that false news on April 1st and useless software to be deleted in 30 seconds on iPhone costs about $2.4 billion to cover additional network bandwidth, disk spaces, and CPU resource of wireless companies and contents providers (e.g. AT&T and Apple). In addition, extra 10.8 Tera Flops of CPU cycle is consumed by playing PPHBN (Post Process Human Body Noise) and RVIIMTC (Rotating Virtual Interface and Inefficient Method to Call) on mobile devices. The Analysis sction shows good agreement between Gigawatt Joule / Hour by Mobile CPU and Global Annual Mean Temperature Changes / Hour which indicates another evidence of global warming. However, PPHBN software has been know as eco-friendly product because it releases PPHBN sounds into the environment without any greenhouse gas agent (e.g. methane).

Abstract

In the last few years, smartphones and similar handheld devices have evolved into fully integrated technology platforms which are used frequently and distributed widely. The useless apps (UA) may be considered as one of the worst in 2010 because of the amount of UA (102,320 apps at the moment) and the network bandwidth affected:  The Internet and congestion control, while private in theory, have not until recently been considered essential. in our research, we disprove the emulation of thin clients, which embodies the confirmed principles of programming languages. In order to accomplish this goal, we argue that the seminal mobile algorithm for the emulation of gigabit switches by O. Zheng is maximally efficient.

Note

This is April 1st Joke.

I started by creating a Windows Phone List Application since I wanted the user to be able to navigate back and forth between the user_timeline screen and the update screen.

The first thing I noticed was that the ListBox was pre-filled with more items than I needed.  You can make changes to them by going into the ViewModels folder and editing MainViewModel.cs.

public MainViewModel() {
    Items = new ObservableCollection<ItemViewModel>() {
        new ItemViewModel() { LineOne = "user_timeline", LineTwo = "20 most recent statuses posted", },
        new ItemViewModel() { LineOne = "update", LineTwo = "Updates user's status", },
    };
}

Since I wanted to keep this tutorial very simple, I added two items:

• getting the feed for a user’s timeline
• updating your own status

Next, I created two Windows Phone Portrait Pages: UserTimeline.xaml and Update.xaml. I needed to make sure that I would be navigating to the correct page when I click on an item in the ListBox, so I added the following code to MainPage.xaml.cs to check the index of the item selected.

private void PageTransitionList_Completed(object sender, EventArgs e) {
    // Set datacontext of details page to selected listbox item
    if (ListBoxOne.SelectedIndex == 0) {
        NavigationService.Navigate(new Uri("/UserTimeline.xaml", UriKind.Relative));
    }
    else if (ListBoxOne.SelectedIndex == 1) {
        NavigationService.Navigate(new Uri("/Update.xaml", UriKind.Relative));
    }
    else {
        // error handling here
    }
 
    FrameworkElement root = Application.Current.RootVisual as FrameworkElement;
    root.DataContext = _selectedItem;
}

I would then get a preview that looks something like this:

Setting up the navigation seemed easy enough. Let’s move on to implementing the feed retrieval. I started by adding a TextBox, a Button and a ListBox to UserTimeline.xaml.

<TextBox Height="31" HorizontalAlignment="Left" Margin="6,67,0,0" Name="tbUsername" Text="" VerticalAlignment="Top" Width="297" />
<Button Content="Get Feed" Height="70" HorizontalAlignment="Left" Margin="314,67,0,0" Name="btnSubmit" VerticalAlignment="Top" Width="160" Click="btnSubmit_Click" />
<ListBox Height="483" HorizontalAlignment="Left" Margin="0,169,0,0" Name="lbContent" VerticalAlignment="Top" Width="480"></ListBox>

Double-click on the button to automatically create the event handler for the button’s click event. Here, we will create an instance of the WebClient class and download a Twitter feed asynchronously. This is very simple since Twitter provides the user_timeline method for you in their REST API.

private void btnSubmit_Click(object sender, RoutedEventArgs e) {
    textBlockPageTitle.Text = "loading feed...";
    WebClient twitter = new WebClient();
    twitter.DownloadStringCompleted += new DownloadStringCompletedEventHandler(twitter_DownloadStringCompleted);
    twitter.DownloadStringAsync(new Uri("http://api.twitter.com/1/statuses/user_timeline.xml?screen_name=" + tbUsername.Text));
}

Remember to add the DownloadStringCompleted event handler before you make a call to DownloadStringAsync. The DownloadStringCompletedEventHandler will fire after the feed is returned. From within this event handler, we can parse the XML reponse by using LINQ to XML.

void twitter_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) {
    try {
        XElement element = XElement.Parse(e.Result);
        lbContent.ItemsSource = from tweet in element.Descendants("status")
                                select new Tweet {
                                    UserName = tweet.Element("user").Element("screen_name").Value,
                                    Message = tweet.Element("text").Value,
                                    ImageSource = tweet.Element("user").Element("profile_image_url").Value,
                                    TweetSource = FormatTimestamp(tweet.Element("source").Value, tweet.Element("created_at").Value)
                                };
        textBlockPageTitle.Text = tbUsername.Text;
    }
    catch (Exception ex) {
        textBlockPageTitle.Text = "ERROR: " + ex.Message;
    }
}

If you notice from the above code, I wrote a helper class called Tweet which contains 4 properties: UserName, Message, ImageSource, and TweetSource. These are the items that I would want to display for each Twitter update in my ListBox.

public class Tweet {
    public string UserName { get; set; }
    public string Message { get; set; }
    public string ImageSource { get; set; }
    public string TweetSource { get; set; }
}

Since the “source” element returned by the XML response may contain URL encoded characters and HTML tags, I used the following method to properly decode this string and strip all HTML tags using a regular expression.

private string StripHtml(string val) {
    return Regex.Replace(HttpUtility.HtmlDecode(val), @"<[^>]*>", "");
}

The format of the date in the “created_at” element returned by the XML response would have to be parsed correctly as well. Below is an example of how I parsed the string into a DateTime object with a specified format.

private string DateFormat(string val) {
    string format = "ddd MMM dd HH:mm:ss zzzz yyyy";
    DateTime dt = DateTime.ParseExact(val, format, CultureInfo.InvariantCulture);
    return dt.ToString("h:mm tt MMM d");
}

Finally, this method below formats the timestamp into something that’s more similar to what you see on Twitter’s site (e.g. 11:05 AM Mar 24th via API)

private string FormatTimestamp(string imageSource, string date) {
    return DateFormat(date) + " via " + StripHtml(imageSource);
}

Going back to UserTimeline.xaml, I added a ListBox template that formats all the data from the XML reponse that’s similar to Twitter’s site. Since we set the DataSource of our ListBox to point to an instance of our Tweet class, we can bind these values by using meta tags like: {Binding UserName}, {Binding Message}, etc.

<ListBox Height="483" HorizontalAlignment="Left" Margin="0,169,0,0" Name="lbContent" VerticalAlignment="Top" Width="480">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal" Height="132">
                <Image Source="{Binding ImageSource}" Height="73" Width="73" VerticalAlignment="Top" Margin="0,10,8,0"/>
                <StackPanel Width="370">
                    <TextBlock Text="{Binding UserName}" Foreground="#FF2276BB" FontSize="28" />
                    <TextBlock Text="{Binding Message}" TextWrapping="Wrap" FontSize="24" />
                    <HyperlinkButton Content="{Binding TweetSource}" Height="30" HorizontalAlignment="Left" VerticalAlignment="Top" FontSize="18" Foreground="#FF999999" />
                </StackPanel>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

That’s all there is too it. Once you compile and run the application in the emulator, you should get something that looks like this:
