ios - MKMapView 双击

Question

以下是我的代码；我没有被 didDoubleTapMap 解雇。

UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(didDoubleTapMap:)];
doubleTap.numberOfTapsRequired = 2;
doubleTap.numberOfTouchesRequired = 1;
[mkMapView addGestureRecognizer:doubleTap];


UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapOnMap:)];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired = 1;


[singleTap requireGestureRecognizerToFail:doubleTap];

[mkMapView addGestureRecognizer:singleTap];

Answer 1

我想念的是，

doubleTap.delegate = self;
singleTap.delegate = self;

也不要忘记实现:

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