title: Pushing view controller from popover controller
body: <p>I have a Popover which I present from a bar button over a navigation controller. This popover will act as a menu. When a row is pressed I want to push a new view controller on the navigation stack. </p>
  
  <p>How do I communicate between the two classes though? The table in the popover is controlled via a UITableViewController subclass and the class that presents the popover is a view controller on the navigation stack.</p>
  
  <p>Any ideas, I'm really stuck on this one.</p>
