For those of you who are still struggling with learning cocos2d, I would recommend Cocos2d for iPhone 0.99 Beginner’s Guide from Packt Publishing. They were nice enough to provide me a copy of the book, and I’ve been slowly going through it while preparing to write a complete review.
The examples the book used were very relevant to the types of games that many developers are trying to create, and the book does a good job of breaking down the steps of putting the games together. Again, for those of you who are new to cocos2d, I would suggest checking it out.
