title: ios get label from tag number
body: <p>I want to get a label's attributes from self so I tried:</p>
  
  <pre><code>UILabel *label = (UILabel *)[self viewWithTag:1];
  </code></pre>
  
  <p>But all I got was an empty UILabel instead of the label I was looking for.  What is correct way to do this.</p>
