If you are going to write a professional iPhone app, youll want to get your arms around Core Data, and theres no better place to do so than in the pages of this book. The book continues right where Beginning iPhone 3 Development left off with a series of chapters devoted to Core Data, the standard for persistence that Apple introduced to iPhone with SDK 3. Jeff and Dave carefully step through each of the Core Data concepts and show you techniques and tips specifically for writing larger applicationsoffering a breadth of coverage you won't find anywhere else. The Core Data coverage alone is worth the price of admission. But there's so much more. This book covers a variety of networking mechanisms, from GameKits relatively simple BlueTooth peer-to-peer model, to the addition of Bonjour discovery and network streams, through the complexity of accessing files via the web. Dave and Jeff will also take you through coverage of concurrent programming and some advanced techniques for debugging your applications. Whether you are a relative newcomer to iPhone development or an old hand looking to expand your horizons, theres something for everyone in More iPhone 3 Development.

To run them on your iPhone or iPod touch, you'll need to join one of Apple's paid iPhone developer programs.
