title: Autocapitalization of words does not work in UITextView
body: <p>I've got a <code>UITextView</code> that needs to autocapitalize words. However, when I call any of these methods, the view does not respond.</p>
  
  <pre><code>[self.fullNameTextView setAutocapitalizationType:UITextAutocapitalizationTypeWords];
  self.fullNameTextView.autocapitalizationType = UITextAutocapitalizationTypeWords;
  </code></pre>
  
  <p>Is this a bug in iOS 8.1? </p>
