title: Custom navigation bar
body: <p>I was crawling Dribble and found the attached design. I was wondering how to do a custom navigation bar like this. I mean how create the navigation bar once and reuse it implicitly for every view controllers.</p>
  
  <p>I was thinking about having a kind of root view controller and inherit for other view controllers, but I don't know how to do this.</p>
  
  <p>Any idea or link will be appreachated!</p>
  
  <p>Cheers.</p>
