title: How do I reload a UIView?
body: <p>How do I reload a UIView after viewDidLoad + viewWillAppear have already been called (and the view displayed)?</p>
  
  <p>If it helps - I'm loading it from a xib/nib file, and expect that calling the method should <em>only</em> trigger viewWillAppear on the controller, not to reload the <em>whole</em> nib file.</p>
