From the Back Cover
Today, virtually every non-trivial iPhone and iPad app must manage data—quickly, smoothly, reliably, and with minimal impact on the CPU to conserve battery life. Core Data, Apple’s ready-made data persistence layer, can help you achieve all these goals. In Core Data for iOS, two leading iOS developers teach you the entire Core Data framework from the ground up. Writing for intermediate-to-advanced iOS developers, Tim Isted and Tom Harrington thoroughly explain how Core Data is used on iOS devices, introduce each of its primary classes, and show how they interact to provide amazing functionality with minimal configuration. You’ll learn how to store, fetch, and validate data; provide it efficiently to views; and much more. Isted and Harrington first give you a firm grounding in the technology, and then present real-world examples. They present multiple sample projects, as well as a start-to-finish, chapter-length case study. Coverage includes
• Understanding Core Data’s features, classes, and interactions
• Using Core Data in MVC-based iOS app development
• Mapping relational data to object models, and building them with Xcode 4’s Data Modeler
• Working with managed objects and using UITableView to display them
• Creating predicates to match numbers, data, and objects
• Maintaining compatibility across versions of an app’s data model
• Tracking managed object contexts across view controllers
• Using Core Data’s automatic Undo functionality
• Integrating abstract entities, entity inheritance, and multiple view controllers into a complete app
• Optimizing for iOS devices’ tight memory limits
• Diagnosing and fixing common Core Data problems
Introducing Addison-Wesley’s new Core Frameworks Series, written for experienced iOS developers by world-class Mac and iOS developers, these are the first comprehensive, code-rich reference guides to Apple’s Core Frameworks.
About the Author
Tim Isted has been writing software for Macintosh computers since 1995. He also builds web applications using Rails, PHP, and .NET and has been known to develop for Windows machines too. Also a professional musician and singing teacher, he tries to divide his time fairly equally between conducting, accompanying, teaching, and writing software. Previous musings on Core Data for desktop development can be found on his blog at www.timisted.net, and he is also co-organizer of NSConference, a new Mac developer conference taking place in both Europe and the USA.
Tom Harrington switched from writing software for embedded systems and Linux to Mac OS X in 2002 when he started Atomic Bird, LLC. After six years of developing highly regarded Mac software he moved to iPhone in 2008. He develops iOS software on a contract basis for a variety of clients. Tom also organizes iOS developer events in Colorado. When not writing software he can often be found on his mountain bike. His website is www.atomicbird.com.
