Implementing Custom Container View Controllers

iOS 5 introduced the ability to create your own custom container view controllers. Prior to iOS 5 you had to use only the stock controllers (tab, navigation, splitview, etc.) or attempt to roll your own, which was a complex endeavor and often hacky. Custom container view controllers are a great way to give your app a unique look and feel. Learn how to implement your own custom container view controller using the new API. We’ll build a page-flipping controller and cover the various gotchas that can arise along the way. The final product will be an open-source controller that you are free to use in your own apps or just study and take apart.
