解决interactivePopGestureRecognizer与UIPanGestureRecognizer冲突

在当前vc里添加

self.navigationController.interactivePopGestureRecognizer.enabled
= YES;
self.navigationController.interactivePopGestureRecognizer.delegate
= self;

UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer
alloc] initWithTarget:self
action:@selector(handlePan:)];
panGesture.delegate =
self;
[view
addGestureRecognizer:panGesture];

设置Delegate

#pragma UIGestureRecognizerDelegate

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer
*)otherGestureRecognizer
{
    return [gestureRecognizer
isKindOfClass:UIScreenEdgePanGestureRecognizer.class];
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer
*)otherGestureRecognizer
{
    return
YES;
}
