Organization of This Book
In this book, we will discuss frameworks and classes that are available in the iOS 7 SDK. This book does its best to teach you the latest and the greatest APIs. As you know, some users of your apps may still be on older versions of iOS, so please consider those users and choose your APIs wisely, depending on the minimum iOS version that you want to target with your apps.
Apple has recommended that you write your apps so that they support and run on iOS 6 and iOS 7. This means you need to use the latest SDK as your base SDK (the SDK that you use to compile your app) and choose iOS 6 as your target, if that’s what your business requirements dictate. If you are required to write your app to support only iOS 7, then you are in for a lot of fun, as you can use all the cool APIs that have been introduced in iOS 7 and discussed in this book.
