title: How to check if UILabel is truncated?
body: <p>I have a <code>UILabel</code> that can be varying lengths depending on whether or not my app is running in portrait or landscape mode on an iPhone or iPad. When the text is too long to show on one line and it truncates I want the user to be able to press it and get a popup of the full text. </p>
  
  <p>How can I check to see if the <code>UILabel</code> is truncating the text? Is it even possible? Right now I'm just checking for different lengths based on what mode I'm in but it does not work super well.</p>
