title: How do i add add a navigation controller to a xib
body: <p>Having only used storyords to subclass a navigation controller before I cant find any tutorial on how to do this for xibs.</p>
  
  <p>How do I add a naviagtion controller to a certain xib  so I can subclass it? Then I can override the rotation for my view.  The part im stuck on is how does the view controller know about the navigation controller?  In storyboards I would manually hook it up to my view controller.  I just cant work it out with xibs? </p>
  
  <p>Ive added a navigation controller next to my views xib...now I need some advice from here.  </p>
  
  <p>Also I've created iPad views from my original iPhone xibs.  When I drag the nav controller from IB its still in the iPhone screen size?</p>
