title: textViewDidBeginEditing - determining which text box is being edited
body: <p>I have a page with 5 <code>UITextView</code> objects. I use the <code>textViewDidBeginEditing:</code> method to animate the <code>observationComment</code> text box which works fine. But now I want to do the same for the other 4, but I can't seem to work out how to determine which text view has been tapped. The <code>observationComment</code> textbox fires each time I click on any of the others.</p>
  
  <pre><code>-(void) textViewDidBeginEditing:(UITextView *) observationComment
  {
      [self.view bringSubviewToFront:observationComment];
  
      [UIView beginAnimations:nil context:NULL];
      [UIView setAnimationDuration:0.5];
      obsCommentLabel.frame= CGRectMake(192, 113, 148, 21);
      observationComment.frame=CGRectMake(191, 135, 710, 250);
      [UIView commitAnimations];
  } 
  </code></pre>
