UIPageViewController scrolling issue with UITableView

I use an horizontal UIPageViewController (SCPageViewController) who manage three UIViewController. Every UIViewController contain a vertical UITableView. I encounter an issue when scrolling horizontally : see this picture The horizontal scroll to switch between UIViewController doesn't work if the user starts the gesture INSIDE the UITableView and OUTSIDE UITableViewCell (RED AREA in the picture) If the user starts the gesture elsewhere, it works. (GREEN AREA in the picture) Any ideas ? Thanks.
