双击并缩放google map ios

Question

有两种委托方法可以更改地图区域：

- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated  
- (void)mapView:(MKMapView *)mapView regionWillChangeAnimated:(BOOL)animated  

我的问题是：是否可以通过双击或缩放来检测地图区域是否已更改？

Answer 1

您可以使用手势识别器检测双击：

UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc]
                         initWithTarget:self action:@selector(handleDoubleTap:)];
recognizer.numberOfTapsRequired = 2;
[self addGestureRecognizer:recognizer];

并使用UIPinchGestureRecognizer对捏缩放进行相同操作>
