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

Thank you @Vladimir for the help! Your answer inspired my answer. I made some changes to make it clearer.

func addAnnotation(coordinate: CLLocationCoordinate2D) {
    let annotation = Annotation()
    annotation.coordinate = coordinate
    annotations.append(annotation)
    mapView.addAnnotation(annotation)
    for index in 0..

Also the protocol in MKMapview needs to implement:

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
    let view = mapView.dequeueReusable(withClass: AnnotationView.self, annotation: annotation)
    if index == 0 {
        view.imageView.image = NSImage(named: "icon_positioning")
    } else {
        view.imageView.image = NSImage(named: "icon_positioning")
    }
    return view
}

By the way, the AnnotationView initialization here is:

public extension MKMapView {
    func dequeueReusable(withClass name: T.Type,annotation: MKAnnotation?) -> T {
        if let view = dequeueReusableAnnotationView(withIdentifier: T.identifier()) as? T {
            return view
        }
        let view = T.init(annotation: annotation, reuseIdentifier: T.identifier())
        return view
    }
}

Thanks again @Vladimir for the answer
