iphone mapkit拖动并获取中心位置 [英] iphone mapkit drag and get center location

问题描述

我有一个Mapview，有一些标记点+当前位置的标记。现在，我想要做的是，当用户拖动或遍历mapview时，我想要在拖动地图后查找新中心位置的坐标（经度，纬度）。

我想再次澄清一下，我不是在说拖动标记/点，而是在谈论拖动地图。

预先感谢。

解决方案寻找 theMapView.region.center 或<$ c $ b> MapView的委托 -mapView：regionDidChangeAnimated：方法中的MapView.centerCoordinate （应该是相同的）。

HI,

I have a Mapview with some marker points + a marker for current location.

Now, what I want to do here is, when user drag or traverse through mapview, I want to find coordinate (latitude, longitude) of the new center location after map has been dragged.

I want to clarify once again, I am not talking about dragging the marker/point, I am talking about dragging the map with touch.

Thanks in advance.

解决方案

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