推荐答案
是在iOS设备上的谷歌地图上不起作用的东西。当地图被拖动时，center_changed会被触发，但中心不会更新，直到拖动完成。所以答案是'不'，你不能这样做。
This is something that doesn't work on google maps on IOS devices. The center_changed is fired when the map is dragged but the center does not update until the drag is complete. So the answer is, 'no', you can not do this.
