title: Adressing UILabel in UIView with viewwithtag not working
body: <p>I have got a <strong>DetailViewController</strong> with a <strong>UIView</strong> (white background). 
  Inside this UIView I have got a couple of labels which I want to adress dynamically. So I decided to use viewWithTag</p>
  
  <p><img src="https://i.stack.imgur.com/m8Dby.png" alt="enter image description here"></p>
  
  <p>Here is my code: </p>
  
  <pre><code>    UILabel *l = (UILabel*)[_bgresult viewWithTag:6];
      l.text = @"TEST";
  </code></pre>
  
  <p>But the text never appears. What do I wrong? </p>
