Quite common with many Audio Player apps is the ability to minimize the detailed episode view, allowing users access to browse for other interesting items in your app. In this lesson, we'll go over the basics of animating between two different anchors for our PlayerDetailsView object. In order to get this to work correctly, we first need to establish where are the maximized top and minimized top anchors. We'll be writing the implementation in MainTabBarController since we need access to the tabBar property. Enjoy.
