title: How can I get the length of text entered into UITextView as the user types?
body: <p>I have a<code>UITextView</code>. I would like to have a way of updating a<code>UILabel</code> as the user times to indicate how many remaining characters are permitted? </p>
  
  <p>In the<code>ViewController</code> the<code>UITextView</code> is referenced as
  <code>IBOutlet UITextView *message;</code></p>
  
  <p>I have tried looking at the show connections inspector and I don't see an edit changed option.</p>
  
  <p>I looked at this example <a href="https://stackoverflow.com/questions/7010547/uitextfield-text-change-event">UITextField text change event</a></p>
  
  <p>But it seemed to apply to<code>UITextField</code> not<code>UITextView</code></p>
