确定是否拖动/移动了MKMapView [英] determine if MKMapView was dragged/moved

问题描述

有没有办法确定是否拖动了MKMapView？

Is there a way to determine if a MKMapView was dragged around?

我希望每次用户使用<$ c $拖动地图时获取中心位置c> CLLocationCoordinate2D center = [locationMap centerCoordinate]; 但是我需要一个委托方法或者一旦用户浏览地图就会触发。

I want to get the center location every time a user drags the map using CLLocationCoordinate2D centre = [locationMap centerCoordinate]; but I'd need a delegate method or something that fires as soon as the user navigates around with the map.

推荐答案

查看 MKMapViewDelegate 参考。

具体来说，这些方法可能很有用：

Specifically, these methods may be useful:

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

确保设置了地图视图的委托属性，以便调用这些方法。

Make sure your map view's delegate property is set so those methods get called.
