title: UILabel sizeToFit in ScrollView
body: <p>I am getting a weird behaviour of UILabel in ScrollView. I am assigning dynamic text to the UILabel and using sizeToFit, I can log the new size which seems to change correctly after assigning text but I can't see the changed size reflected in both the simulator and the real device. This is the log before assigning and after assigning text</p>
  
  <pre><code>--txt Frame {{15, 325}, {291, 36}}
  --txt Frame1 {{15, 296}, {291, 446.5}}
  </code></pre>
  
  <p>As you can see, the size (height) changes though I don't see the changes on device and simulator. Please help.</p>
