title: UIBarButtonItem image/glyph in Standard UIButton
body: <p>I'm trying to create a 'Refresh' button containing the standard UIBarButton refresh system glyph, which, when tapped, will animate a custom view, then fire another selector to call the intended refresh action. </p>
  
  <p>I know I could do this with images and two inner views added to a custom view, but is there any way to do it with the standard glyphs from UIBarButtonItem? Are they available at all for UIButtons? </p>
