title: Insert a image in UINavigationBar instead of text
body: <p>i have this piece of code which permits me to insert a title on the UIbar (if i'm not wrong) of the app.</p>
  
  <pre><code>[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(ApplicationDidBecomeActive:) name:UIApplicationDidBecomeActiveNotification object:nil];
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(goToAlbum) name:@"GetAlbumNotif" object:nil];
  self.title = @"Events List";
  </code></pre>
  
  <p>Can you please give me an orientation to this?
  Thanks!</p>
