This book is merely about 230 pages, all color printed. In my opinion, full color printing is a complete waste. True, the presentation of the book is excellent, but the content is not something we should expect. Throughtout the book, there isn't a single complete project. The authors just copied-and-pasted code fragments that they copied from the Internet onto the book. They didn't put too much explaination into the code, even they did, that was too naive.

This book is not for beginner, you will need reasonable iPhone programming experience for the book. Not that the book is very sophisticated, but the chapters aren't ordered properly. They would talk about something then suddenly move to something totally irrelevant in the next section in the same chapter. And in the next chapter or so, they would switch their focus back to the previous chapter. This makes very difficult for a reader to digest unless you already know most of the stuffs.

I don't recommend this book to anybody. In my opinion, this is a quick-cash-earning book for the authors. Simply study the official Apple documentation.
