Refresh MKAnnotationView on a MKMapView

Question

I\'d like to a-synchronically load images for my custom MKAnnotationView; I\'m already using the EGOImageView-framework (it goes very well with UITableViews), but I fail to make

Answer 1

I wanted to refresh user location pin with new selected avatar. I found another fast solution for that case. I have 2 screens. The first one is for selecting avatar and the second is for displaying user on map.

swift 5 You can change user location image by creating MKAnnotationView

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {

    if annotation is MKUserLocation {
        let userIdentifier = "UserLocation"
        var userView = mapView.dequeueReusableAnnotationView(withIdentifier: userIdentifier)
        if userView == nil {
            userView = MKAnnotationView(annotation: annotation, reuseIdentifier: userIdentifier)
        } else {
            userView?.annotation = annotation
        }

        userView!.image = UIImage(named: "avatar1") //your image

        return userView
    }

    return nil
 }

So if user will change avatar to something else, for example to "avatar2" it won't refresh.

In order to refresh user location image i added this code in viewWillAppear()

 self.mapView.showsUserLocation = false
 self.mapView.showsUserLocation = true
