title: iOS - UITextView doesn't draw text?
body: <p>I have a UITextView on the screen.
  This UITextView is covered by a UIView.</p>
  
  <p>When I set the text for this UITextView, if the textView is not visible (UIView is covering it), it doesn't draw the text.</p>
  
  <p>So when I remove the view that is covering my textView there is no text in my textView. If I try scrolling the textview the text will appear suddenly.</p>
  
  <p>any way to force the UITextView to draw the text at all times? (This only happens when I have too much text in it (about 1000 characters))</p>
  
  <p>I tried calling <code>[textView setNeedsDisplay]</code>, before and after setting 'text' and it didn't fix the problem</p>
