如何使用覆盖整个视图的地图视图处理UIScreenEdgeGestureRecognizer？

Question

I have iOS program over here, with a map view covering the whole container view. I want the map view to handle the UIScreenEdgeRecognizer , since it is covering the whole container view. I think it would be better to let the gestureRecognizers array to reference the recognizer. But the pan gesture of the map view is interrupting the screen edge recogniser. I tried gestureRecognizer:shouldFailRequireFailureOfGestureRecognizer and all that, but it still doesn't work. But solution would you people recommend? Could I let the gestureRecognizers array of the container view reference the screen edge recogniser?

What I did was to add a view with a 10pt width and clear color background over the edge I needed the gesture recognizer and I added the gesture recognizer to this view.

In the picture, the white rectangle on the right is the view which will have the gesture recognizer. You should change the background color to clear color.

The view outlet:

@property (weak, nonatomic) IBOutlet UIView *rightEdgeGestureView;

Add the gesture recognizer to the view on the screen right edge:

- (void)setupGestureRecognizer {

      UIScreenEdgePanGestureRecognizer *gestureRecognizer = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(gestureHandler:)];
      gestureRecognizer.edges = UIRectEdgeRight;
      [_rightEdgeGestureView addGestureRecognizer:gestureRecognizer];
 }
