Each chapter is supposed to be an hour, but as you progress through the book each chapter gets lighter and lighter, and your hour turns out to be minutes. Rather than giving any detail it's skims over it's subject. But it's biggest crime is perhaps that it's focusing on the programming environment too much throughout rather than on the language, which is why you bought the book in the first place.
On the language side it's poor. As the book is trying to be as light as possible the examples given are poor, and afterwards you'd struggle to use anything that you've "learned". I challenge anybody to write any sort of program after reading this book. It doesn't even cover looping sufficiently! With these glaring omissions it is a poor excuse for a book on this subject.
I used this book to back up what I'd learned from "Programming in Objective-C" by Stephen G. Kochan (ISBN 0321811909) and would highly recommend this as an alternative as it is far superior, and perhaps a book on Xcode 4 for the programming environment.
I can not recommend this book.

I have never returned a book to amazon before but have done after reading half of this book. I have read other Sams teach yourself books and have found them quite useful but this one is terrible. Each 1 "hour" session is about 10 minutes reading, would be even less if you skip were the author repeats himself on the previous page or two.
There is very little about objective-c so far as it is more about xcode, such as setting up a project and using version control. There are simple typos in the code, i.e. missing end brackets and also in one code section (page 76) an note from an editor was obviously ignored, so much so that the note from the editor is still in the source code "Suggest removing this. RMCG". I have given up reading this book (even though it will prob take 5 hours max to read cover to cover).

I bought this book expecting a step by step process to learn Objective C. The book assumes you have knowledge beyond the chapters in the book, and I find it to be a touch unfair to the end user. Stick with it, and perhaps buy another book to re-inforce the knowledge learned from this book. I dont like rating products at such a low level, but the book shouldn't have made it past editorial in it's release format.
