title: UIPageViewController & Touch events
body: <p>I have followed the following tutorial to implement my collection view <a href="http://www.appcoda.com/uipageviewcontroller-storyboard-tutorial/" rel="nofollow noreferrer">here</a></p>
  
  <p>There is a back button implemented in the root view; however it does not receive any touch events as they are intercepted by the pageContentViewController. </p>
  
  <p>From stackoverflow I have found the current thread of discussions which deal with a similar topic <a href="https://stackoverflow.com/questions/7788780/uipageviewcontroller-gesture-recognizers">here</a>. There is the following solution:</p>
  
  <pre><code>for (UIGestureRecognizer *gR in self.view.gestureRecognizers) {
      gR.delegate = self;
  }
  </code></pre>
  
  <p>However, it does not work as there is no gestureRecognizers as my pageViewController is in scroll mode; not curl. I cannot find any other solutions which do not point towards the code above.</p>
  
  <p>What would be then the approach for the scroll mode? Any hint is highly appreciated! </p>
