title: UITextView on a UIAlertView (multi-line input)
body: <p>i'm having a couple of problems when i try to alloc a <strong>UITextView</strong> on an AlertView.
  Here is my code:</p>
  
  <pre><code>UIAlertView* minhaCritica = [UIAlertView new];
  minhaCritica.title = @"7Arte";
  [minhaCritica addButtonWithTitle:@"Cancelar"];
  [minhaCritica addButtonWithTitle:@"Enviar"];
  minhaCritica.message = @"Escreve a tua crítica:\n\n\n\n";
  minhaCritica.delegate = self;
  [minhaCritica show];
  
  CGRect frame = minhaCritica.frame;
  frame.origin.y -= 100.0f;
  minhaCritica.frame = frame;
  
  criticaTxtView = [UITextView alloc];
  [criticaTxtView setFont:[UIFont systemFontOfSize:16.0f]];
  [criticaTxtView initWithFrame:CGRectMake(20.0, 80.0, 245.0, 40.0)];
  [minhaCritica addSubview:criticaTxtView];
  [criticaTxtView becomeFirstResponder];
  </code></pre>
  
  <p>my problem is when i start inputing text, the text view doesn't scroll as i type. It should scroll one line up, when the first 2 rows are full.</p>
  
  <p>Can anyone help me with this?
  Here's a video showing the problem: <a href="http://www.welove.com.pt/7arte.swf" rel="nofollow noreferrer">http://www.welove.com.pt/7arte.swf</a></p>
  
  <p>Also, i'm having trouble getting the text the user inputed into a fiel.
  i worked with:
  criticaText = [[alertView textField] text];
  but now it doesn't work with the code above. </p>
