The highly acclaimed introduction to Cocoa–recommended most by experienced Mac OS X developers now updated and expanded.

Here's what critics said about the first edition:

"Reading this book is the absolute best way to learn how to harness the power of this amazing technology."
Andrew Stone, President, Stone Design, www.stone.com

"Make sure this is the first one you pick up. It's the best book for a beginning Cocoa programmer."
–From the review on HyperJeff.net&

"I love this book. The descriptions are clear, the examples logical. Everything a programmer needs to get up to speed on Cocoa."
Dave Mark, Editor, MacTech Magazine

To help programmers develop applications for Mac OS X, Apple is now giving away XCode, Interface Builder, and the Cocoa frameworks–the tools used to create Safari, GarageBand, Mail, and the iApps. Cocoa® Programming for Mac® OS X, Second Edition, will give you a complete understanding of how to use these tremendously powerful tools and frameworks to write full-featured applications for the Mac.

Guiding programmers through the key features of Cocoa, this book emphasizes design patterns that enable you to predict the behavior of classes you have never used before. Written in a tutorial format, it takes you step-by-step through the creation of six applications and an Interface Builder palette. Each project introduces several new ideas, and as each concept or technique is discussed, the author, drawing on his own extensive experience, shows you the right way to use it.

Updated for Xcode and Mac OS X 10.3, new chapters in this second edition include coverage of OpenGL, AppleScriptability, the undo manager, creating frameworks, and a brief introduction to using GNUstep on Linux.
