Become an Xcoder - Start Programming the Mac Using Objective-C

Apple provides you with all the tools you need to create great Cocoa applications, for free. This set of tools, known under the name Xcode, comes with Mac OS X, or you can download it from the developer section on Apple’s website. Several good books on programming for the Mac exist, but they assume that you already have some programming experience. This book doesn’t. It teaches you the basics of programming, in particular Objective-C programming, using Xcode. After some 5 chapters, you will be able to create a basic program without a Graphical User Interface (GUI). After a few more chapters, you will know how. | Become an Xcoder Start Programming the Mac Using Objective-C By Bert Altenberg Alex Clarke and Philippe Moughin License Copyright 2008 by Bert Altenburg Alex Clarke and Philippe Mougin.
