Moving a CLLocation by x meters

Question

I have a CLLocation defined, and I\'d like to move that point x meters to the east and y meters to the south. How may I achieve that?

Answer 1

A simpler solution is to use MKMapPoints.

Convert your original coordinates, and any offset distances you need to MKMapPoints using this:

let coordinatesInMapPoints = MKMapPointForCoordinate(CLLocationCoordinate2D)
let distancesInMapPoints = yourDistanceInMeters * MKMapPointsPerMeterAtLatitude(CLLocationDegrees) // Do this for both x and y directions if needed.

Then make a new MKMapPoint by simply adding your offset distances to your original coordinates:

let newCoordinatesInMapPoints = MKMapPointMake(coordinatesInMapPoints.x + distancesInMapPoints, coordinatesInMapPoints.y)

Finally, convert the new coordinates from a MKMapPoint back to CLLocationCoordinate2D:

let newCoordinate = MKCoordinateForMapPoint(newCoordinatesInMapPoints)

No complex conversion calculations needed.
