MKMapView double tap

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

我缺少的是，

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

另外不要忘记实现：

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