Get Started Fast with Objective-C 2.0
Programming for OS X Mountain Lion, iOS 5.1, and BeyondFully updated for Xcode 4.4, Learning
Objective-C 2.0, Second Edition, is today’s most
useful beginner’s guide to Objective-C 2.0. One step at a
time, it will help you master the newest version of Objective-C 2.0
and start writing high-quality programs for OS X 10.8 Mountain
Lion, iOS 5.1, and all of Apple’s newest computers and
devices.Top OS X and iOS developer Robert Clair
first reviews the essential object and C concepts that every
Objective-C 2.0 developer needs to know. Next, he introduces the
basics of the Objective-C 2.0 language itself, walking through code
examples one line at a time and explaining what’s happening
behind the scenes.This revised edition thoroughly introduces
Apple’s new Automated Reference Counting (ARC), while also
teaching conventional memory-management techniques that remain
indispensable. Carefully building on what you’ve already
learned, Clair progresses to increasingly sophisticated techniques
in areas ranging from frameworks to security. Every topic has been
carefully chosen for its value in real-world, day-to-day
programming, and many topics are supported by hands-on practice
exercises.Coverage includesВ·В В В В В
