A carefully written introduction to Objective-C and object oriented programming for developers new to iOS or Mac programming Updated to include the latest information on the iPad and the latest iOS 5 SDK and Xcode 4.2 Detailed examples and well-crafted exercises greatly expedite the learning process. Written by a bestselling author with a patented technique for teaching in a manner and at a pace that readers find accessible and easy to learn with. Programming in Objective-C is a concise, carefully written tutorial on the basics of Objective-C and object-oriented programming for Apple's iOS and Mac platforms. The book makes no assumptions about prior experience with object-oriented programming languages or with the C language (which Objective-C is based upon). Because of this, both beginners and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C. Readers can also learn the concepts of objectoriented programming without having to first learn all of the intricacies of the underlying C programming language. This unique approach to learning, combined with many small program examples and exercises at the end of each chapter, makes Programming in Objective-Cideally suited for either classroom use or self-study. While the Objective-C language itself has not gone through many changes since the introduction of Objective-C 2.0, the Apple development tools that programmers use for Objective-C development on the Mac and on iOS continue to change significantly from year to year. This edition has been fully updated for the significant changes in iOS 5 and Xcode 4.2. One of the biggest changes is Automatic Reference Counting (ARC). This edition gives detailed coverage of how to use ARC to improve and simplify memory management in Objective-C programming.
Stephen Kochan is the author and coauthor of several bestselling titles on the C language, including Programming in C (Sams, 2004), Programming in ANSI C (Sams, 1994), and Topics in C Programming (Wiley, 1991), and several Unix titles, including Exploring the Unix System (Sams, 1992) and Unix Shell Programming (Sams, 2003). He has been programming on Macintosh computers since the introduction of the first Mac in 1984, and he wrote Programming C for the Mac as part of the Apple Press Library. In 2003 Kochan wrote Programming in Objective-C (Sams, 2003), and followed that with another Mac-related title, Beginning AppleScript (Wiley, 2004).
