title: Check if UITextView is truncated?
body: <p>Is there anyway to check if UITextview has been truncated?  I have to use UITextView.</p>
  
  <p>My textview is set to:</p>
  
  <pre><code>textview.textContainer.maximumNumberOfLines = 2
  </code></pre>
  
  <p>and </p>
  
  <pre><code>textview.sizeToFit()
  </code></pre>
  
  <p>I've tried checking if </p>
  
  <pre><code>textview.text.containsString("...")
  </code></pre>
  
  <p>But this does not output true.</p>
  
  <p>I've also tried :</p>
  
  <pre><code>let textSize : CGSize = textview.text.sizeForWidth(textview.frame.width, font: UIFont.mainFontThin(13))
  </code></pre>
  
  <p>^^^Then check the actual height vs the textSize.height:</p>
  
  <pre><code>print("textSize Height: \(textSize.height)")
  print(textview.bounds.size.height)
  </code></pre>
