This is almost last day since I’m leaving tomorrow noon. We have more advanced sessions today, such as Mastering Interface Builder session which should be continued from introduction one. I scheduled my Lab session afternoon around 4:30 pm and this should wrap up our project deployment.

Interesting thing is, I saw a couple of underground iPhone advertise company’s activities. There are a couple of people distributing flayer around entrance and I saw a pile of flayers in bathroom.

Another interesting thing is, I found a Japanese staff working at lab to support Japanese visitors. He told me there are more than 300 Japanese visitors. It seems that Japanese and Chinese people had their own reception on the first day. Shoooot, I was not invited!

The lab session was just talking about what’s available in iTunes Connections web login screen. One thing, I though that I can setup my own price, but actually I can not. Apple setup tier for pricing. That’s bad news for us. After this session, I have clear idea of distributing our app.

WWDC08 Bash will start in half hour, it’s beer time!

Day2 started. I arrived there around 8 am before session starts. Thank you for free food and Odawalla drinks which I usually do not purchase because of overpriced healthy drinks. I will list a couple of sessions that I attended here.

iPhone Application Development Fundamentals

Basic things that we’ve already covered so far. The speaker insists to grab right idea about MVC design pattern. He also guided additional sessions to connected with this, such as Understanding ControllerView and TableView lectures. Some demo about Interface Builder to stick action and outlet. I like the concept that he explained, “Controllers are like glue to stick them together”.

So, I have been struggling to learn Objective C. Here is a snippet of code that might be helpful. Basically you can use NSString’s initWithFormat method to create a new NSString object and use it just like sprinf function in C

[[NSString alloc] initWithFormat:@”(%f,%f)”,center.x,center.y]
