Restrict UIPageViewController (with TransitionStyleScroll) pan gesture to a certain area

Question

In my app I have a RootPageViewController which contains the UIPageViewController and one or more DetailPageViewController with a UITableView as a childview.

Answer 1

My solution in Swift:

let myview = UIView(frame: CGRect(x:0, y:0, width:320, height:320))
//dummy view that defines the area where the gesture works
self.view.addSubview(myview)

for x in self.pageViewController!.view.subviews 
{ if x is UIScrollView
  { myview.addGestureRecognizer(x.panGestureRecognizer) } 
}
