无法将CGPoint分配给CLLocationCoordinate2D

Question

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

This code gives me ( Cannot assign a value of type 'CGPoint' to a value of type 'CLLocationCoordinate2D' ) error.

Answer 1

It should be:

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

Instead of:

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

because it is returning you a CGPoint , not a CLLocationCoordinate2D , which causes the error when you assign newCoordinate to annotation.coordinate .
