title: UITextView change height instead of scroll
body: <p>By default, the UITextView's contentView becomes scrollable when there is too much text to fit into the textview based on it's height.</p>
  
  <p>I'd like to disable this and instead, update the height of the UITextView to fit in the text. The reason I'm doing this is because I'm adding the UITextView as a subview of a UIScrollView which should handle the scrolling, much like in the native Mail app (when you enter text, the whole view scrolls up, not just the textview.</p>
  
  <p>Anyone got some ideas / has run into the same problem before?</p>
