title: Programmatically click the leftbarbutton (back-button) of a pushViewController of the navigationController
body: <p>I want to click the back button in the navigationBar programmatically in my second view.
  It's call it this way:</p>
  
  <pre><code>Archiv *archiv = [[Archiv alloc] initWithNibName:@"Archiv" bundle:nil];
      archiv.title =  [NSString stringWithFormat:@"Archiv %@", [sender titleForState:UIControlStateNormal]];
      [self.navigationController pushViewController:archiv animated:YES];
  </code></pre>
  
  <p>And now i'm in the Archiv.m and after a specific event i want to get back to the first controller (without clicking the back button) - instead i want to perform the click programmatically.</p>
  
  <p>Is it possible for this case?</p>
  
  <p>Helpful would be to know which method is called if i click on this button, so don't even have to perform the click.</p>
