title: UILabel with tag, can't set text
body: <p>I'm having a problem with labels. I have a couple of labels that I need to change with help of tags. I do this in my code, but it gives an exception 
  <code>-[UIView setText:]: unrecognized selector sent to instance</code>
  This is my code:</p>
  
  <pre><code>UILabel *label = (UILabel *)[self.view viewWithTag:0];
  
  label.text = @"empty";
  </code></pre>
  
  <p>Any help appreciated, thanks.</p>
