title: How do I force a UITextView to scroll to the top every time I change the text?
body: <p>OK, I'm having some problem with the <code>UITextView</code>. Here's the issue:</p>
  
  <p>I add some text to a <code>UITextView</code>. The user then double clicks to select something.
  I then change the text in the <code>UITextView</code> (programatically as above) and the <code>UITextView</code>  scrolls to the bottom of the page where there is a cursor. </p>
  
  <p>However, that is NOT where the user clicked. It ALWAYS scrolls to the bottom of the <code>UITextView</code> regardless of where the user clicked. </p>
  
  <p>So here's my question: How do I force the <code>UITextView</code> to scroll to the top every time I change the text? I've tried <code>contentOffset</code> and <code>scrollRangeToVisible</code>. Neither work.</p>
  
  <p>Any suggestions would be appreciated.</p>
