title: Disable/enable scrolling in UIPageViewController
body: <p>I got a <code>viewController</code> which inherits from <code>UIPageViewController</code> ( <code>@interface PageScrollViewController : UIPageViewController</code> ) Now I'm wondering how I can enable and disable the scrolling from the <code>UIPageViewController</code>? When using a <code>UIScrollView</code> you would do <code>setScrollEnabled:NO</code> and  <code>self.view.userInteractionEnabled = NO;</code> isn't an option since this blocks the whole <code>UIView</code> instead of just the scrolling.</p>
  
  <p><strong>EDIT</strong>
  This is in the <code>PageScrollViewController : UIPageViewController</code> class:</p>
  
  <pre><code>if ([[notification name] isEqualToString:@"NotificationDisable"]){
      NSLog (@"Successfully received the disable notification!");
      for (UIGestureRecognizer *recognizer in self.gestureRecognizers) {
          recognizer.enabled = NO;
      }
  }
  </code></pre>
