iphone - iphone mapkit 拖动并获取中心位置

Question

你好，

我有一个带有一些标记点的 Mapview + 当前位置的标记。

现在，我在这里要做的是，当用户拖动或遍历地图视图时，我想在地图被拖动后找到新中心位置的坐标（纬度，经度）。

我想再次澄清一下，我不是在谈论拖动标记/点，我是在谈论通过触摸拖动地图。

提前致谢。

Answer 1

Look for theMapView.region.center or theMapView.centerCoordinate (should be the same) in your MapView's delegate -mapView:regionDidChangeAnimated: method.

Answer 2

Judging by this document:

http://developer.apple.com/iphone/library/DOCUMENTATION/MapKit/Reference/MKMapView_Class/MKMapView/MKMapView.html

You can get that with the centerPosition property of your MKMapView. To tell when the location changes, implement the -mapView:regionDidChangeAnimated: method in your MKMapViewDelegate.
