title: Master-Detail with UITabBarItem?
body: <p>Can you embed a Split-View Controller in a UITabBarController? I have a UITabBarController in my appdelegate on the window, and I tried adding a segue to my split view controller, but when I press the correlating tab for the DetailViewController it just shows a blank screen? Is it possible to even have a split-view controller as a tab in a tabbarcontroller?</p>
