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
Testing device properties so your app can take full advantage of the iOS unit it’s running on
Seamlessly sharing documents and data across apps and moving control between apps
Presenting exceptionally attractive text with freeform text typesetting
Building touch-based apps that leverage Bezier curves, splines, and other geometric tools
Securing network apps via authentication, system keychains, and OAuth
Accessing and processing image data to create special effects
Integrating live camera feeds and user snapshots
Presenting audio to users and enabling them to interact with it
Effectively using Address Book frameworks and GUI classes
Building advanced location apps with Core Location geopositioning and MapKit
Creating connected game play with GameKit/Game Center: device-to-device networking, shared leaderboards, and Internet-based matches
Integrating secure in-app purchasing with StoreKit
Communicating with users from web-based services via push notifications
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.
