Product Description
Want to write applications for iOS or the Mac? This introduction to programming and the Objective-C language is the first step on your journey from someone who uses apps to someone who writes them.
Based on Big Nerd Ranch's legendary Objective-C Bootcamp,¿this book covers C, Objective-C, and the common programming idioms that enable developers to make the most of Apple technologies.
This is the only introductory-level book written by Aaron Hillegass, one of the most experienced and authoritative voices in the iOS and Cocoa community.
Compatible with Xcode 4.2, iOS 5, and Mac OS X 10.7 (Lion), this guide features short chapters and engaging style to keep you motivated and moving forward.

And my experience?
First of all, I cannot emphasise enough that you have to get your hands dirty. Type in the examples, force yourself to do the exercises and try to think up some little project of your own to work on. It's not easy, but keep at it. The book will not be able to answer all your questions or solve all your problems - it is the nature of Objective-C that the methods are too numerous to list - but there are websites to consult: not only bignerdranch.com but also stackoverflow.com and techotopia.com as well as Apple itself.
Secondly, did I have to learn some C before learning Objective-C? Only after 70-odd pages do you get to Objective-C and there's a bit of un-learning to do. (The final part of the book is also on C.) Some texts launch you straight into Objective-C from page 1. It does seem that a knowledge of C is necessary but I guess the question is whether you do it first or later. Who knows.
There are a couple of text errors and this really means that you need to consult the supporting website. But overall, I would recommend the book.
I also tried several other books and it made me realise that jumping into Cocoa without a solid grounding in objective C was not overly wise.
This touches on C, goes right into Objective C, then introduces you to the other frameworks.
I have been critical at times of this author's other books, but this work is his best - the explanations for the same concepts that he attempted to explain in other books, is now excellent.
(Of particular note is the brilliant description of why we need protocols)
I have gone through the entire book and the source code is all good and up to date. The challenges really force you to get your hands dirty, and are highly useful to consolidate learning.
The interactive forum is a bonus too, which the author does frequent.
Highly recommended.
