title: Problems with UIScrollView
body: <p>I have such a UIControllerView:</p>
  
  <pre><code>--Main View
    --UIScrollview
      --Label 1
      --Label 2
  </code></pre>
  
  <p>I have a short (1 line text) for Label 1, and I have a very long text for Label 2, so I've set for Label 2: <strong>0 lines, sizeToFit()</strong>. Okay, and when I'm running my app in simulator, everything looks okay, but when I'm trying to scroll the screen:</p>
  
  <ol>
  <li>There is no scrollbar, while I've not disabled it</li>
  <li>My long Label 2 is not scrolling fully, it's just bouncing from the bottom of screen</li>
  </ol>
  
  <p>And this code I have:</p>
  
  <pre><code>self.labelSecond.text = content //very long content
  self.labelSecond.sizeToFit()
  </code></pre>
  
  <p>For UIScrollView I've enabled AutoSizing. Please help, how to make my long label scroll fully, not bounce from the bottom?</p>
