  <p>…and we can dismiss these sheets by sliding the presented view controller down <em>(interactive dismissal)</em>. Although the new "pull-to-dismiss" feature is pretty useful, it may not always be desirable. </p>
  
  <p><strong>THE QUESTION:</strong> How can we turn the interactive dismissal off? 
  <em>- Bear in mind we keep the presentation style the same.</em></p>
