When details of iOS 6 were first announced at the Apple World Wide Development Conference in June, 2012 it seemed, on the surface at least, that the iOS 5 edition of this book would not need to be significantly updated for iOS 6. After gaining access to the pre-release versions of the iOS 6 SDK and working with the new features, however, it quickly became clear that whilst there are areas that have not changed since iOS 5, there is much more to the new features of iOS 6 than it had at first appeared. In actual fact, 23 new chapters had to be written to cover the new features of iOS 6 and every code example updated to reflect the changes made to Objective-C.

How you make use of this book will depend to a large extent on whether you are new to iOS development, or have worked with iOS 5 and need to get up to speed on the features of iOS 6. Rest assured, however, that the book is intended to address both category of reader.

For New iOS Developers

If you are entirely new to iOS development then the entire contents of the book will be relevant to you.

Beginning with the basics, this book provides an outline of the steps necessary to set up an iOS development environment. An introduction to the architecture of iOS 6 and programming in Objective-C is provided, followed by an in-depth look at the design of iPhone applications and user interfaces. More advanced topics such as file handling, database management, in-app purchases, graphics drawing and animation are also covered, as are touch screen handling, gesture recognition, multitasking, iAds integration, location management, local notifications, camera access and video and audio playback support. New iOS 6 specific features are also covered including Auto Layout, Twitter and Facebook integration, event reminders, App Store hosted in-app purchase content, collection views and much more.

The aim of this book, therefore, is to teach you the skills necessary to build your own apps for the iPhone. Assuming you are ready to download the iOS 6 SDK and Xcode, have an Intel-based Mac and some ideas for some apps to develop, you are ready to get started.

For iOS 5 Developers

If you have already read iPhone iOS 5 Development Essentials, or have experience with the iOS 5 SDK then you might prefer to go directly to the new chapters in this iOS 6 edition of the book. As previously mentioned, if you have already read iPhone iOS 5 Development Essentials, you will find no fewer than 23 new chapters in this latest edition.

Chapters included in this edition that were not contained in the previous edition are as follows:

• The Basics of Modern Objective-C

In addition, the chapter entitled Using Xcode Storyboarding has been updated to include coverage of the new segue unwinding feature of iOS 6 and An Overview of iOS 6 Table Views and Xcode Storyboards has been modified to introduce the new iOS 6 model for reusing Table View cells.

Finally, all the code examples have been updated to reflect the changes to Objective-C including the removal of the viewDidUnload: method, literal syntax for number, array and dictionaries and default property synthesis.
