body: <p>Is there a way to pop the view controller when the user switches tabs? </p>
  
  <p>I have a tabbar with a navigationController on one of the tabs.  The user selects a row in a table which pushes a viewController onto the navigationController containing the table.   Then the user switches tabs to a new view.  In the new view he hits a button that brings him back to the table tab.  The problem is that the table inside the navigationController still has a view pushed onto it.   </p>
