ios - 无法将 CGPoint 分配给 CLLocationCooperative2D

Question

var touchPoint = gestuRerecognizer.locationInView(self.map)
var newCoordinate = map.convertPoint(touchPoint, fromCoordinateSpace: self.map)
var annotation = MKPointAnnotation()
annotation.coordinate = newCoordinate

此代码给我(无法将“CGPoint”类型的值分配给“CLLocationCoordinate2D”类型的值)错误。

Answer 1

应该是:

let newCoordinate = map.convertPoint(touchPoint, toCoordinateFromView:self.map)
annotation.coordinate = newCoordinate

代替:

var newCoordinate = map.convertPoint(touchPoint, fromCoordinateSpace:self.map)

因为它返回给您的是 CGPoint，而不是 CLLocationCoordinate2D，这会在您将 newCoordinate 分配给 注释时导致错误。坐标.
