So I have got this scenario: 

-NavigationController
 -PageViewController
  -MapViewController
   -UIView
    -MKMapView (Full Screen)
  -OtherViewController

So basically, I want it to switch pages (viewcontrollers) when catching the UIScreenEdgeGesture. But having the map in one of them, this doesn't work properly.

I have researched a lot (!) about this but still haven't found the right solution.

I believe that the correct approach here is to delegate this gesture to the nextResponder in the hierarchy.

So I have successfully captured the gesture when the user swipes on the left edge of the screen.

Right now my issue is I can't manage to pass the gesture to the UIView (MKMapView.superview). I have two questions :

// 1. How to do it // 2. Is this the right approach?

Let me know your thoughts on this one please!

EDIT 1: Adding some code and Images of story board

UIScreenEdgePanGestureRecognizer *popRecognizer = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:[self.view superview] action:@selector(handlePopRecognizer:)];
popRecognizer.edges = UIRectEdgeLeft;
popRecognizer.delegate = self;

[self.mapView addGestureRecognizer:popRecognizer];

enter image description here

EDIT 2: I want this behaviour : Use UIScreenEdgePanGestureRecognizer without moving MKMapView

But when the gesture is recognized, I want it to switch to the page on the left (OtherViewController)

FINAL EDIT: THE workaround that I've come up with consists in putting a clear view on top of the map, leading to the desired behaviour. Not happy with the solution, but it works for now.

When you create your gesture, make the target the superview, and call the method in the superview for the action, something like:

    UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:[self.view superview] action:@selector(swipeHandler:)];

Don't know if MKMapView.superview would work, that depends on if MKMapView is an instance. Hard to know what you're referring to without code.

  • There isn't much code to add. I have tried your approach unsuccessfully yet. I am trying to understand which method to call so that the pagecontroller handles the gesture – jonypz Dec 09 '14 at 22:57
  • I am using the default pageviewcontroller so I guess I should call pageViewController:viewControllerBeforeViewController: . But I guess the target is not right. When I print self.view.superview, it returns null. – jonypz Dec 09 '14 at 23:07
