Preface

Building on the phenomenal success of its predecessor, iOS 5 includes over 200 new user features as well as an updated SDK containing over 1,500 new APIs. iOS 5 looks set to reinforce the iPhone's dominance in the smartphone market.

iOS 5 Essentials will help you learn how to build simple, yet powerful iOS 5 applications, incorporating iCloud Storage, Twitter, Core Image and Newsstand integration.

You will start by learning about what's new in iOS 5. You'll look at the iCloud Storage APIs, Automatic Reference Counting, Twitter, and AirPlay integration, how to use the various Core Image filters using the Cocoa framework, and the new features of the iOS 5 SDK. After this, you'll jump straight in and create applications using Xcode and Interface Builder using the new storyboard layout. We then finish up by learning how to make your applications run smoothly using the Xcode instruments.

In this book, I have tried my best to keep the code simple and easy-to-understand. I have provided step-by-step instructions with loads of screenshots at each step to make it easier to follow. You will soon be mastering the different aspects of iOS 5 programming, as well as mastering the technology and skills needed to create some stunning applications.
