This is a follow up post to my 2 previous posts on the same subject. Please check them here. iPhone SDK 3.0 - Playing with Map Kit iPhone SDK 3.0 - Playing with Map Kit - Part 2 We also started a basics training program in iPhone development. If you or some one you know wants to learn development and live around NYC area, Please promote this Blog Entry:http://blog.objectgraph.com/index.php/2009/05/13/iphone-developer-training-in-ny-city/ Meetup Group: http://www.meetup.com/iPhoneDeveloper Many of the users were asking me how to draw a polyline on this map. From what i can see in the documentation...

I got some time to play with some more Map Kit stuff today. And I was able to add annotations. UPDATE: Follow the 3rd part here. http://blog.objectgraph.com/index.php/2009/04/08/iphone-sdk-30-playing-with-map-kit-part-3/ There are a couple of classes to be familiar with MKMapView This is our main class that displays a map. It inherits from UIView, so you can just initialize it and add it to your MainView MKPinAnnotationView This view is helpful if you would not like to subclass the MKAnnotationView, It provides a basic pin annotation with interaction enabled MKReverseGeoCoder This...

UPDATE: Follow the second part here http://blog.objectgraph.com/index.php/2009/04/03/iphone-sdk-30-playing-with-map-kit-part-2/ I started looking at the Map Kit API for developing a quick and dirty - Find where you parked your car - application. There is no programming guide for Map Kit yet on the developer pages for Apple, So I decided to share some some of it here. The main class that supports a Map is called MKMapView You need to include the header MapKit/MapKit.h Also dont forget to add a reference to the Framework MapKit.Framework The code is relatively simple. Here...

I could access Lon/Lat/Alt values from iPhone's Location Manager class. This is kind neat. I got exact same value that I put my apartment address in google map. When I run this on the simulator, it always returns a address in Santa Clara. Is this Apple's company building address or something? Let me know if anyone familiar with the address below. Download the source code from here LocationSampleViewController.h /* #import CoreLocation/CLError.h CoreLocation/CoreLocation.h CoreLocation/CLLocation.h CoreLocation/CLLocationManager.h CoreLocation/CLLocationManagerDelegate.h */ @interface...

My newest love is TextMate, the ultimate Mac OSX text editor. I am so used to having TextPad on Windows that i felt lost with out a good  editor. I used vi for a while, but it felt awkward after sometime.  As you know from my previous blog posts, I am learning Objective-C to program the iPhone. I am using textmate now to program simple console based Objective C programs. So if you want to compile them using command line use the following gcc sample.m -o sample -L /System/Library/Frameworks/Foundation.framework/Foundation

After a little struggle, got my iPhone changed to version 2.0, was able to connect to our exchange server at school and was able to launch an OpenGL application on the iPhone. So, no more excuses. We at objectgraph have to get our act together and start building applications for iPhone starting yesterday.

Cool news today!! After sending apple all our company's documents, we got approved for the developer program. I purchased it for $99 + Tax, the store status says it is electronically delivered, but i did not get any email with a certificate key or anything. Will keep you posted on  the latest news!

Kiichi and I really liked the demo from apple about the iPhone SDK. If you haven't seen it, check it out@ http://www.apple.com/quicktime/qtv/iphoneroadmap/ We at ObjectGraph think the new app store feature will level the playing field for all developers, big(EA) and small(OG). Now its up to developers to create new applications and make them success stories. So We started developing in Objective C. With its kinda wierd syntax coming from C#, Java, ActionScript and Python, but here is my first try anyway :-) I am creating a MyPoint class with a distance function that takes a reference...

Just finished learning about the viewport metatag and implemeted this for dictionary on iPhone. Usage: Just type a few words and click on the reference. http://www.objectgraph.com/dictionary/iphone.html

I got my iPhone a while ago and only now started looking at some development. Naturally i am trying to get our AJAX Dictionary to work on iPhone. But looks like iPhone does not support the onkeyup event in Javascript. Actually it does not support a bunch of keyboard events (there is no real physical keyboard on iphone, so its hard to distinquish keyup, keydown etc), so i am thiking of just putting a button after the text is inputted. There is an onchange event but it only triggers if you focus outside the textbox. Here is the first version of it. http://www.objectgraph.com/dictionary/iphone.html
