title: How to set a picture programmatically in a NavBar?
body: <p>I have a detailview with a navigation bar with a back button and a name for the view.
  The navigation bar is set programmatically.
  The name presented is set like this.</p>
  
  <p><code>self.title = NSLocalizedString(name, @"");</code></p>
  
  <p>The name depends on the presented view.</p>
  
  <p>Now I would like to also present a small icon on the navigation bar which also is depends on the view.</p>
  
  <p>How do I do that?</p>
