It's really exciting for me when I see someone who learned Objective-C from my book and this forum release an app to the App Store. Here's a game called Bubble Pets from one of our members : http://itunes.apple.com/app/id395136354?mt=8#
Check it out!
Best of luck to miiifan!!!!
Earlier this year I picked up your book, Programming in Objective-C 2.0. After going through the book and all the lessons, I started looking into the cocos2d framework, and some months later, my first iPhone game has just been released to the App Store.
Anyway, I can't believe this day ever came, but here it is. Before reading your book, I only had a vague idea what a method was, let alone any idea on how to make an entire (albeit simple) game or iPhone application. Your book was the first steps in making the impossible possible. Thank you!
