In some surveys, Objective-C is now the third most popular programming language, up from fifth place in 2011.
O’Reilly recently has published the awaited third edition of Learning Cocoa with Objective-C, with coverage of Xcode 4.2 and iOS 6.
The book’s two authors definitely know the Cocoa framework. They have been developing for it since the Mac first supported it. And their experience and expertise shine forth in this well-written, smoothly organized how-to guide.
They have, they note, “seen the ecosystem of Cocoa and Objective-C development evolve from a small programmer’s niche to one of the most important an d influential development environments in the world.”
Their 339-page, 20-chapter book assumes that you have some programming experience and at least know how to use an OS X and iOS device. Otherwise, it is a solid choice for learning Cocoa with Objective-C from the ground up. It offers clear descriptions and practical exercises, plus numerous code samples, screenshots and other illustrations.
Paris Buttfield-Addison’s and Jon Manning’s bottom-line goal, successfully met here, is to “give you the knowledge, confidence, and appreciation for iOS and OS X development with Cocoa, Cocoa Touch, and Objective-C.”
