Praise for Learning Objective-C 2.0 “With Learning Objective-C 2.0, Robert Clair cuts right to the chase and provides not only comprehensive coverage of Objective-C, but also time-saving and headache-preventing insights drawn from a depth of real world, hands-on experience. The combination of concise overview, examples, and specific implementation details allows for rapid, complete, and well-rounded understanding of the language and its core features and concepts.” —Scott D. Yelich, Mobile Application Developer “There are a number of books on Objective-C that attempt to cover the entire gamut of object-oriented programming, the Objective-C computer language, and application development on Apple platforms. Such a range of topics is far too ambitious to be covered thoroughly in a single volume of finite size. Bob Clair’s book is focused on mastering the basics of Objective-C, which will allow a competent programmer to begin writing Objective-C code.” —Joseph E. Sacco, Ph.D., J.E. Sacco & Associates, Inc. “Bob Clair’s Learning Objective-C 2.0 is a masterfully crafted text that provides in-depth and interesting insight into the Objective-C language, enlightening new programmers and seasoned pros alike. When programmers new to the language ask about where they should start, this is the book I now refer them to.” —Matt Long, Cocoa Is My Girlfriend (www.cimgf.com) “Robert Clair has taken the Objective-C language and presented it in a way that makes it even easier to learn. Whether you’re a novice or professional programmer, you can pick up this book and begin to follow along without knowing C as a prerequisite.” —Cory Bohon, Indie Developer and Blogger for Mac|Life “I like this book becaus
