Dynamically change MGLPointAnnotation image on Mapbox iOS SDK

Question

I have an application that uses a map Mapboxon its iOS SDKand existing markers ( MGLPointAnnotation) on it.

I want to change the marker image when I select it.

MGLPointAnnotationhas no property image, and I tried calling the delegate method mapView(mapView, imageForAnnotation annotation), but it did not work.

Any idea how I can do this?

Thank!

• I am sure that it is not possible to change the annotation after adding to the map (except annotation)

• mapView(mapView, imageForAnnotation annotation) only called when an annotation is added.

• What you can do is use desegete didselect

  func mapView(_ mapView: MGLMapView, didSelect annotationView: MGLAnnotationView){ //code }

, . ,

func mapView(_ mapView: MGLMapView, imageFor annotation: MGLAnnotation) -> MGLAnnotationImage? {
//code
}
