Welcome to Learn Objective-C on the Mac! This book is designed to teach you the basics of the Objective-C language. Objective-C is a superset of C and is the language used by many (if not most) applications that have a true OS X or iOS look and feel. In addition to presenting Objective-C, this book introduces you to its companion, Apple’s Cocoa (for OS X) and Cocoa Touch (for iOS) toolkits. Cocoa and Cocoa Touch are written in Objective-C and contain all the elements of the OS X and iOS user interfaces, plus a whole lot more. Once you learn Objective-C, you’ll be ready to dive.
