Core Animation is the technology underlying Apple’s iOS user interface. By unleashing the full power of Core Animation, you can enhance your app with impressive 2D and 3D visual effects and create exciting and unique new interfaces. ¿ In this in-depth guide, iOS developer Nick Lockwood takes you step-by-step through the Core Animation framework, building up your understanding through sample code and diagrams together with comprehensive explanations and helpful tips. Lockwood demystifies the Core Animation APIs, and teaches you how to make use of Layers and views, software drawing and hardware compositing Layer geometry, hit testing and clipping Layer effects, transforms and 3D interfaces Video playback, text, tiled images, OpenGL, particles and reflections Implicit and explicit animations Property animations, keyframes and transitions Easing, frame-by-frame animation and physics Performance tuning and much, much more!

Apple has made it easy to get started developing for iOS out of the box. To access the true power of iOS, however, you need to go beyond these simple tools and APIs. Experienced app developer Shawn Welch teaches you how to tap into the true potential of iOS by incorporating some of the most powerful technologies it has to offer. Using Core Data and iCloud, you'll learn how to store information locally and sync seamlessly across multiple devices and platforms. Leverage iOS 5's new Twitter APIs, which provide painless Twitter and OAuth support using the new Accounts framework. Use Location Services to incorporate new iOS 5 features, such as reverse geolocation lookup and region notifications. Incorporate rich media into your apps using Graphics, Animation, Audio, Video, and post-processing photo filters and analysis through Core Image. Finally, explore Newsstand, which lets you create your own periodical content and push new content to devices, even when the app is not running.

Provides information on using iOS 4 to create applications for the iPhone, iPad, and iPod Touch.

Apple’s Core Animation framework enables Mac OS X, iPhone, and iPod touch developers to create richer, more visual applications–more easily than ever and with far less code. Now, there’s a comprehensive, example-rich, full-color reference to Core Animation for experienced OS X and iPhone developers who want to make the most of this powerful framework. Marcus Zarra and Matt Long reveal exactly what Core Animation can and can’t do, how to use it most effectively–and how to avoid misusing it. Building on your existing knowledge of Objective-C, Cocoa, and Xcode, they present expert techniques, insights, and downloadable code for all aspects of Core Animation programming, from keyframing to movie playback. Zarra and Long thoroughly review similarities and differences between Core Animation on the Mac and iPhone, helping you write code that can easily move between platforms. They also present a full chapter of innovative techniques and proven “rules of thumb” for optimizing Core Animation’s real-world performance. Coverage includes: Taking full advantage of Core Animation’s lightweight layers and views Using keyframes to gain complete control over your animations Creating startling effects with Core Animation transforms Leveraging Core Image’s powerful filtering capabilities from within Core Animation Playing QuickTime movies using Core Animation’s QTMovieLayer Using the OpenGL layer to achieve greater control over movie playback Integrating advanced Quartz Composer visualizations into your user interfaces How to use helper layers to draw gradients, composite shapes, and replicate sublayers Adding mouse and keyboard user interaction points, and much more...
