Want to write applications for iOS or the Mac? This introduction to programming and the Objective-C language is the first step on your journey from someone who uses apps to someone who writes them.

Based on Big Nerd Ranch's legendary Objective-C Bootcamp,¿this book covers C, Objective-C, and the common programming idioms that enable developers to make the most of Apple technologies.

This is the only introductory-level book written by Aaron Hillegass, one of the most experienced and authoritative voices in the iOS and Cocoa community.

Compatible with Xcode 4.2, iOS 5, and Mac OS X 10.7 (Lion), this guide features short chapters and engaging style to keep you motivated and moving forward. At the same time, Aaron’s determination that you understand what you’re doing—or at least why you’re doing it—encourages you to think critically as a programmer.

Aaron Hillegass, a former employee at NeXT and Apple, has nearly two decades experience programming and teaching Objective-C, Cocoa, and, more recently, iOS. Aaron is the author of Cocoa Programming for Mac OS X and co-author of iOS Programming: The Big Nerd Ranch Guide. Both best-sellers, these books have helped many people develop and enhance their programming skills. In 2001, Aaron founded Big Nerd Ranch and began developing intensive courses that teach programming in a focused, distraction-free environment. He is currently working on site plans and blueprints for the new Ranch to be located in Atlanta, GA.
