Learning Cocoa with Objective-C, 2nd Edition (ISBN 0596003013)

OK...:
While this book is very detailed and has a lot of information in it about Cocoa programming, it starts off too quickly. You might be discouraged by the assumptions the author makes about how much C (and programming in general) you know. If you are experienced in computer programming, then you will find this book to be a blast and will learn objective -C in no time at all. However, if you aren't too good with programming, start off with some online tutorials or other books, as you will get lost after reading the first two chapters or so.

Low on details:
If only Apple put as much effort in its books as it does in its iPods... This text skips over all sorts of details regarding the Cocoa framework it purports to teach, while repeating many mundane details (like how to create a project) over and over. The authors focus mostly on Interface Builder. If that is what you need, though, I'd still recommend the Internet instead.

Quality, Apple reviewed literature.:
As with most O'reilly books this one is not a let down. I was most impressed to find out that is actually written by Apple Computer and then was handed to James Duncan Davidson to make it flow. It has a great explanation of Object Oriented programming as it pertains to Objective-C. Although if you are looking to get into OOP for the first time I would suggest a higher-level language such as Java (the syntax can get in the way of learning the concepts and ideas with Obj-C / C++). The book is titled to cover upto MacOS 10.2. I am using Leopard (10.5) and the only differences (so far) are: the GUI screenshots in the book are, well, out of date; and the default naming conventions for Xcode files are different. Neither of these is a big issue though. Its a Good book.

Great Start to Learn OS X Programming:
This book is a great start to learn the best OS X programming technology. As a professional developer. The title says it "Learning Cocoa with Objective C". Avoid the book "Cocoa in a Nutshell" until you know Cocoa and Objective C and want a good refeerence. I also plan to read: "Programming in Objective C" and "Cocoa Programming", but only after mastering the material in this book.

A book for Cocoa programmers:
The book is an useful guide for who needs to learn Cocoa programming, and needs to learn also Objective-C.
