The Advanced iOS 6 Developer’s Cookbook brings together reliable, proven solutions for cutting-edge iOS 6 development. World-renowned iOS expert Erica Sadun covers device-specific development, document/data sharing, Core Text, networking, image processing, onboard cameras, audio, Address Book, Core Location, GameKit,StoreKit, push notifications, and more.

 

As in her previous bestselling iOS books, Sadun translates today’s development best practices into working code, distilling key concepts into concise recipes that are easy to understand and transfer into your own projects. This isn’t just cut and paste. Using her examples, Sadun fully explains both the “how” and “why” of advanced and specialized iOS 6 development.

 

All code is tested with iOS 6 features and iPhone, iPad, and iPod touch capabilities. Throughout, every chapter groups related tasks together, so you can jump straight to your solution without having to identify the right class or framework first. Coverage includes

Erica Sadun is the bestselling author, coauthor, and contributor to several dozen books on programming, digital video and photography, and web design, including the widely popular The iOS 5 Developer’s Cookbook. She currently blogs at TUAW.com and has blogged in the past at O’Reilly’s Mac Devcenter, Lifehacker, and Ars Technica. In addition to being the author of dozens of iOS-native applications, Erica holds a Ph.D. in Computer Science from Georgia Tech’s Graphics, Visualization, and Usability Center. A geek, a programmer, and an author, she’s never met a gadget she didn’t love. When not writing, she and her geek husband parent three geeks-in-training, who regard their parents with restrained bemusement, when they’re not busy rewiring the house or plotting global dominance.
