title: Multiline Navigationbar Title
body: <p>I am trying to set the title label in my navigation bar to allow multiple lines. I have custom navigation controller code that I am placing the multiline code into. I know that the code already there works, but my multiline part is not working.</p>
  
  <pre><code>let titleLabel = UILabel()
  titleLabel.frame = CGRectMake(0, 0, self.navigationBar.frame.width, self.navigationBar.frame.height * 2)
  titleLabel.numberOfLines = 0
  titleLabel.lineBreakMode = .ByWordWrapping
  
  navigationItem.titleView = titleLabel
  </code></pre>
  
  <p>But the text still runs off at the end. I've also tried putting this into the individual view controller itself, adding <code>self.navigationController?.</code> in front of <code>navigationItem</code> with the same results.</p>
  
  <p>Is there something I'm missing in my code that would keep the title label from using multiple lines?</p>
