title: How to implement a down arrow / caret (like in the iOS 9 Music app) in an iOS Swift project?
body: <p>I am looking for the best way to create a down arrow (caret?) at the right hand side of a UILabel in a view that is centered in a UINavigationItem. </p>

  <p>The whole thing should look like the down arow in the iOS 9 Music app. The text of the label will change during runtime and the title/text of the label including the arrow should be centered like in this screenshot:</p>

  <p>Currently I append a <code>\u{25BE}</code> character at the end of the text like this:</p>
  
  <pre><code>self.lblSelectedAlbum.text = self.lblSelectedAlbum.text! + " \u{25BE}"
  </code></pre>
  
  <p>But this has several negative effects:</p>
  
  <ol>
  <li>It looks a cluncky</li>
  <li>If the label text is too long, the down arrow will disappear</li>
  </ol>
  
  <p>Any ideas on how to implement this best? Thanks!</p>
