Determine if MKMapView was moved / moved in Swift 2.0

Question

How to determine when the user dragged or moved MKMapView, for example, to prevent the user from automatically switching to the current location.

Answer 1

Note. This answer became possible and was adapted from Yano's answer to the same question for Objective-C here: determine if MKMapView was moved / moved . Thanks Jano .

To correctly detect the dragging of a map, you must add a UIPanGestureRecognizer. This is a sign of gesture recognition (pan = drag).

Step 1: Add a gesture recognizer to viewDidLoad (Swift 2)

override func viewDidLoad() { super.viewDidLoad() // All your other setup code let mapDragRecognizer = UIPanGestureRecognizer(target: self, action: "didDragMap:") mapDragRecognizer.delegate = self self.mapView.addGestureRecognizer(mapDragRecognizer) } 

Swift 3 version higher than gesture recognition setting (selector syntax has changed)

 override func viewDidLoad() { super.viewDidLoad() let mapDragRecognizer = UIPanGestureRecognizer(target: self, action: #selector(self.didDragMap(gestureRecognizer:))) mapDragRecognizer.delegate = self self.mapView.addGestureRecognizer(mapDragRecognizer) } 

Step 2: Add the UIGestureRecognizerDelegate protocol to the view controller so that it works as a delegate.

 class MapViewController: UIViewController, UIGestureRecognizerDelegate 

Step 3: Add the following code for UIPanGestureRecognizer to work with existing gesture recognizers in MKMapView:

 func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWithGestureRecognizer otherGestureRecognizer: UIGestureRecognizer) -> Bool { return true } 

Step 4: In case you want to call your method once instead of 50 times for a drag, define in your village the state of "drag" or "drag":

 func didDragMap(gestureRecognizer: UIGestureRecognizer) { if (gestureRecognizer.state == UIGestureRecognizerState.Began) { print("Map drag began") } if (gestureRecognizer.state == UIGestureRecognizerState.Ended) { print("Map drag ended") } } 

Hope this helps someone in need!
