title: UIScrollView doen't scroll when is into a UIPageViewController
body: <p>I'm trying to use a UIScrollView as the content view into a PageViewController, I've configured the Page controller as it is on the sample project of xcode.</p>
  
  <p>The problem is that the content has a Scroll view but it just doesn't scroll at all, I have seted the Content size and the properties for the scroll view.. I guess it is right configured.</p>
  
  <pre><code>- (UIScrollView *)scrollView
  {
      if (_scrollView == NULL) {
          _scrollView = [[UIScrollView alloc] init];
          _scrollView.backgroundColor      = [UIColor whiteColor];
          _scrollView.scrollEnabled        = TRUE;
          _scrollView.alwaysBounceVertical = TRUE;
      }
      return _scrollView;
  }
  </code></pre>
  
  <p>Then, I'd attached the gestures of my view to be the UIPageViewController gestures array, this was preventing a navigation bar to perform well, so I made a validation on:</p>
  
  <pre><code>gestureRecognizerShouldBegin:
  </code></pre>
  
  <p>And it is ok now.</p>
  
  <p>I don't know how to fix this issue :S</p>
