title: iOS7 UITextView contentsize.height alternative
body: <p>I'm porting one of apps from iOS 6.1 to iOS 7. I'm using a layout where there's a <code>UITextView</code> that has a fix width, but it's height is based on its contentsize. For iOS 6.1 checking the contentsize.height and setting it as the textview's frame height was enough, but it doesn't work on iOS 7. </p>
  
  <p>How can I then create a <code>UITextView</code> with a fixed width, but dynamic height based on the text it's showing?</p>
  
  <p>NOTE: I'm creating these views from code, not with Interface Builder.</p>
