Overview of this book

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.

Summary


In this chapter, we learned about the benefits of using iCloud, and how to access them through their storage APIs. We looked at how we can incorporate iCloud features within our code, how to store and retrieve key-value data, and how to store documents within a folder inside our application sandbox.

We also learned about the process involved in how to search and locate a document within an iCloud repository, as well as learned to handle and avoid file-version conflicts when multiple copies of the same file are being updated on more than one device, and then being submitted to the iCloud repository.

In the next chapter, we will learn about the new debugging features of OpenGL ES, and how this new debugger in Xcode allows you to track-down issues specific to OpenGL ES directly within your code, right from within the IDE.
