title: Disable UIPageViewController when ModalViewController opened
body: <p>I am totaly new to this site, but I already like it :-)</p>
  
  <p>I found it by searching for a question about the UIPageViewController.</p>
  
  <p>I have a normal UIPageViewController App, in which I open a ModalViewController for setting up some settings...</p>
  
  <p><strong>Now the Problem:</strong> :-)</p>
  
  <p>If I click on the done Button on the right side of the ModalView, to dismiss it, the PageViewController turnes the page, because he thinks that he is meant by that click ;-)</p>
  
  <p>Can I disable the PageViewController GestureRecognizer as long as I have a ModalView opened?</p>
  
  <p>Is there a method to disable and later his recognizer?</p>
  
  <p>thank you for your help in advance...</p>
  
  <p>cu Matze</p>
