Cocoa Programming is a comprehensive work that starts as a fast-paced introduction to the OS architecture and the Cocoa language for programmers new to the environment. The more advanced sections of the book will show the reader how to create Cocoa applications using Objective-C, to modify the views, integrate multimedia, and access networks. The final sections explain how to extend system applications and development tools in order to create your own frameworks.
It covers the additions that Objective-C adds to the C language in about 27 pages. If you already know C, that is all you need to get going. If you don't already know C this book will not teach it to you.
Consider that, counting the index, the book is 1245 pages of small print and has none of the usual fluff that eats up half the book, it is a lot of valuable information; all meat and very little fat.
It has in-depth sample code for about everything you are going to need or want to do with OS X. Just as important, it not only tells you what you can do, but what you should do and explains why.
Most programmers never learn a particular tool or object until they want to use it in a program. This book has example code for just about anything you would want to try and clear explanations of what you must know to use it. Having a working example with source is just the ticket when you are learning a new object.
If you want to program for OS X, drop what you are doing and order this book. If you are already an old hand at programming OS X, I'll bet there are more than a few things in this book that you don't know.
All in all, I would recommend this book for anyone who is looking for a detailed, organized, and complete Cocoa reference. It might not be as good for someone who was never programmed before since I don't think it has the *best* tutorials when compared to the other Cocoa books on the market, but my goodness is this an indispensable reference that will stay on my bookshelf for the remainder of my Cocoa programming career.
