title: UITextView has no events
body: <p>I am developing an iPhone application which requires a multiline text field (UITextView) to capture some text.</p>
  
  <p>When the user touches inside the textView it becomes firstResponder and displays the keyboard. What I really need it to do is remove the keyboard when the user is finished. Normally with a text field the return/done button press would signal the end of typing and I would use the delegate to resign first responder. However with a multiline textview I want the user to be able to add a new line so that is not possible.</p>
  
  <p>My next option would be to resign first responder if there is a touch up outside of the text view. The problem here is that there are no events declared on UITextView which I can see in interface builder.</p>
  
  <p>How can I create a multiline text field in an iPhone app which will release first responder at a sensible time when the user is done with it?</p>
