title: ios-fontawesome on UIBarButtonItem
body: <p>I'm trying to use <a href="https://github.com/alexdrone/ios-fontawesome" rel="nofollow noreferrer">iOS FontAwesome</a> to set an icon on a bar button, like this:</p>
  <pre><code>[self.barButton setTitle:[NSString fontAwesomeIconStringForEnum:FACamera]];
  </code></pre>
  <p>and also with this:</p>
  <pre><code>[self.barButton setTitle:[NSString fontAwesomeIconStringForIconIdentifier:@&quot;fa-camera&quot;]];
  </code></pre>
  <p>No matter what identifier I use the result is the same:</p>
  <p><img src="https://i.stack.imgur.com/hCjjM.png" alt="enter image description here" /></p>
  <p>What could be wrong?</p>
