title: UITextView inside UIScrollView with AutoLayout
body: <p>I am trying to place UITextView inside UIScrollView with AutoLayout with no luck. What I have tried is,</p>
  
  <ul>
  <li>I placed UIScrollView inside the main view in Storyboard</li>
  <li>I placed UITextView inside UIScrollView in Storyboard and disabled Scrolling Enabled</li>
  <li>I set constraints (leading, trailing, top, bottom) on UIScrollView</li>
  <li>I set constraints (top, leading, trailing, height) on UITextView</li>
  <li>I created IBOutlet of height constraint of UITextView</li>
  <li>I set a text (a lot of text which can cause scrolling) on UITextView in viewDidLoad()</li>
  <li>I set a height constraint of UITextView with the code below. I have tried it right after setting text in viewDidLoad() and viewDidLayoutSubviews() with no luck</li>
  </ul>
  
  <p><code>self.textViewHeightConstraint.constant = [self.textView sizeThatFits:CGSizeMake(self.textView.frame.size.width, FLT_MAX)].height;</code></p>
  
  <p>UITextView is getting its height, but UIScrollView isn't. Is there anything I've missed?</p>
