How can I detect which annotation was selected in MapView

Question

I\'ve made a few annotations inside the Map and when I tap on them I see some informations and I have a button that opens Maps and with the right information that I can\'t take

Answer 1

For Swift 4

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
    var selectedAnnotation = view.annotation
}

Answer 2

For that you can use selected Annotation from didSelectAnnotationView, then store that annotation to instance variable and after that used annotation in your Button action method.

var selectedAnnotation: MKPointAnnotation?

func mapView(mapView: MKMapView, didSelectAnnotationView view: MKAnnotationView) {
    self.selectedAnnotation = view.annotation as? MKPointAnnotation
}

func info(sender: UIButton) {
    print(selectedAnnotation?.coordinate)
}

Edit: As of you have custom MKAnnotation class you need to use that.

var selectedAnnotation: Islands?

func mapView(mapView: MKMapView, didSelectAnnotationView view: MKAnnotationView) {
    self.selectedAnnotation = view.annotation as? Islands
}
