The best-selling introduction to Cocoa, once again updated to cover the latest Mac programming technologies, and still enthusiastically recommended by experienced Mac OS X developers. 'Aaron's book is the gold standard for Mac OS X programming books-beautifully written, and thoughtfully sculpted. The best book on Leopard development.' -Scott Stevenson, www.theocacao.com 'This is the first book I'd recommend for anyone wanting to learn Cocoa from scratch. Aaron's one of the few (perhaps only) full-time professional Cocoa instructors, and his teaching experience shows in the book.' -Tim Burks, software developer and creator of the Nu programming language, www.programming.nu 'If you're a UNIX or Windows developer who picked up a Mac OS X machine recently in hopes of developing new apps or porting your apps to Mac users, this book should be strongly considered as one of your essential reference and training tomes.' -Kevin H. Spencer, Apple Certified Technical Coordinator If you're developing applications for Mac OS X, Cocoa Programming for Mac OS X, Third Edition, is the book you've been waiting to get your hands on.
