This is Volume 2 of a 2-Volume book.

iOS 5 was one of the biggest upgrades to iOS so far, and has a ton of awesome features that you'll definitely want to start using in your apps. The only problem is, there's not a ton of documentation or sample code on the APIs, so they're often quite hard to learn!

This is where iOS 5 By Tutorials comes in! The goal of the book is to help intermediate and advanced iOS developers get up-to-speed with the APIs introduced in iOS 5 in the quickest and easiest way - via tutorials!

Updated for iOS 6. This new second edition is fully up-to-date with iOS 6 and Xcode 4.5. Although the book focuses on APIs introduced in iOS 5, the chapters have been updated to work on iOS 6, use Modern Objective C syntax, and more.

This book is for intermediate or advanced iOS developers, who already know the basics of iOS development but want to upgrade their skills to iOS 5.
