title: UISlider inside UIPageViewController
body: <p>I have a PageViewController which is initialized like this:</p>
  
  <pre><code>self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll
                            navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
  </code></pre>
  
  <p>On one of the pages, there's a UISlider.</p>
  
  <p>My problem is that when I have transitionstyle set to <code>UIPageViewControllerTransitionStyleScroll</code>, it takes 150-200 ms before <code>beginTrackingWithTouch</code> is invoked on the slider.
  This behavior is not seen when I use <code>UIPageViewControllerTransitionStylePageCurl</code>, where the UISlider is selected instantly.</p>
  
  <p>This means that unless the user waits a bit before dragging the slider (a video progress), the page will turn instead, which is far from ideal.</p>
  
  <p>The Page curl animation does not meet the demands of the app, so any explanation or workaround is appreciated.</p>
