title: Rotate UIViewController Programmatically?
body: <p>I am trying to rotate a UIViewController by 180 degrees programmatically. Let's say I hit a "Rotate" button. That said button should rotate the screen and it's content by 180 degrees. My iOS Target has only Portrait as the supported interface orientation under deployment info. Would this be an issue?</p>
  
  <p>Thanks! </p>
