MapKit annotation how to add detail disclosure info button?

Question

I am putting annotation on a map and after clicking the pin, there should be a detail disclosure info buttonon the right side, so I can add more code after tapping the button. But when I run the project, clicking on the pin, there is no info buttonshows up. Can anyone provide code to add disclosure info button?

I am expecting an info button on the right:

My Code:

extension ViewController: MKMapView{


func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {



  }

Create a MKAnnotationView and add a button to it. So:

    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
        if annotation is MKUserLocation { return nil }

        if let annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "") {
            annotationView.annotation = annotation
            return annotationView
        } else {
            let annotationView = MKPinAnnotationView(annotation:annotation, reuseIdentifier:"")
            annotationView.isEnabled = true
            annotationView.canShowCallout = true

            let btn = UIButton(type: .detailDisclosure)
            annotationView.rightCalloutAccessoryView = btn
            return annotationView
        }
    }

@Rob, do you mean something like this `if annotation.isMember(of:MKUserLocation.self){ return nil }`? – Rashwan L Sep 27 '16 at 21:01
