Erica Sadun

I dedicate this book with love to my husband, Alberto,
who has put up with too many gadgets and too
many SDKs over the years while remaining both
kind and patient at the end of the day.

Rich Wardwell

I dedicate this book to my wife, Julie, who was relegated
to single-parent status during this endeavor,
and my children, Davis and Anne, who never stopped
asking me to play with them even after countless refusals.

Welcome to a new Core iOS Developers Cookbook!

With iOS 7, Apple introduced the most significant changes to its mobile operating system since its inception. This cookbook is here to help you get started developing for the latest exciting release. This revision introduces all the new features and visual paradigms announced at the latest Worldwide Developers Conference (WWDC), showing you how to incorporate them into your applications.

For this edition, the publishing team has split the cookbook material into manageable print volumes. This book, The Core iOS Developers Cookbook, provides solutions for the heart of day-to-day development. It covers all the classes you need for creating iOS applications using standard APIs and interface elements. It provides recipes you need for working with graphics, touches, and views to create mobile applications.

And theres Learning iOS Development: A Hands-on Guide to the Fundamentals of iOS Programming, which covers much of the tutorial material that used to comprise the first several chapters of the cookbook. There youll find all the fundamental how-to you need to learn iOS 7 development from the ground up. From Objective-C to Xcode, debugging to deployment, Learning iOS Development teaches you how to get started with Apples development tool suite.

As in the past, you can find sample code at GitHub. Youll find the repository for this Cookbook at https://github.com/erica/iOS-7-Cookbook, all of it refreshed for iOS 7 after WWDC 2013.

If you have suggestions, bug fixes, corrections, or anything else youd like to contribute to a future edition, please contact us at . We thank you all in advance. We appreciate all your feedback, which helps make this a better, stronger book.
