On first time load, it's working fine and move along with MapView, but if I change the marker position and then if I drag the map view that marker is not moving with map.it's just stuck on that place. It's only happening in iOS 11 or below that version.
See the screenshot its just stuck that place.moving mapview.
我不知道这会起作用,但你可以改变注释使用的坐标
[yourAnnotation setCoordinate:newCoordinate];
请看看这个问题是否可以帮助你MKMapView moving Annotations Automatically - animate them?
