title: use the same UINavigationBar object in all children views
body: <p>hi im developing an ios aplication and the ui was desigbed using the storyboard (first time using it) so i have the folowing:</p>
  
  <ul>
  <li>entry point: navigation Controller</li>
  <li>rootView view controller (push to many other view some of one are UITableView)</li>
  <li>and then i programatically push (in some controllers) a view loaded from a nib (no problem on this)</li>
  </ul>
  
  <p>each controller has a defined title.</p>
  
  <p>what i want to do is put a rigth button on the nav bar of all view controller so i can push (programatically) to another controller (wish is in a nib, but i coul move it to the SB whit no problem)</p>
  
  <p>i have tried:</p>
  
  <ul>
  <li>using a custom class and an nib file but i get the same uncustumised nav bar</li>
  <li>overwriting initWithCoder so i can redirect it to de nib file but get an infinite loop (StakOverflow, yay!)</li>
  <li><p>using a second class to avoid the infinite loop but get an exception:</p>
  
  <blockquote>
    <p>Terminating app due to uncaught exception 'NSGenericException', reason: 'This coder requires that replaced objects be returned from initWithCoder:</p>
  </blockquote></li>
  <li><p>add the button manually in the init method of the navbar class, no efect</p></li>
  <li>replace the navigation bar in the navigation controller  initWithCoder, no efect</li>
  <li>same but in the viewDidLoad method of the navigation controller, no efect</li>
  <li>same but in the rootView Controller, no efect</li>
  </ul>
  
  <p>the code i was using was this (and a few variations):</p>
  
  <pre><code>UIBarButtonItem *BTN = [[UIBarButtonItem alloc] 
        initWithImage:[[UIImage alloc] initWithContentsOfFile:@"img.png"] 
        style:UIBarButtonItemStyleBordered 
        target:self 
        action:@selector(pushView)];
  
  [[self navigationItem] setRightBarButtonItem:BTN];
  </code></pre>
  
  <p>is ther any way that i can archive this, or should i do it manually view per view?</p>
  
  <p>--thanks</p>
