Swift2 iOS9 - wie benutzerdefinierte Bild anstelle von Standard-Anmerkungs rote Pin in meinem Code erhalten

Question

Hier ist mein Code. Ich habe alle verfügbaren Lösungen ausprobiert, aber ich bin nicht in der Lage, das Bild, das ich wünsche, anstelle des Standard-Anmerkungs-roten Stiftes in meinen Code zu stellen.

import MapKit 

class ViewController: UIViewController, MKMapViewDelegate { 

@IBOutlet var map: MKMapView! 

override func viewDidLoad() { 
    super.viewDidLoad() 

    var location = CLLocationCoordinate2DMake(18.956449, 72.810597) 

    var span = MKCoordinateSpanMake(0.009, 0.009) 
    var region = MKCoordinateRegion(center: location, span: span) 

    map.setRegion(region, animated: true) 

    var annotation = MKPointAnnotation() 
    annotation.coordinate = location 
    annotation.title = "Wilson College" 
    annotation.subtitle = "Commerce College" 

    map.addAnnotation(annotation) 
    print("showing on map") 

    mapView(map, viewForAnnotation: annotation) 


} 



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

    let identifier = "MyPin" 
    print("inside viewForAnnotation") 
    if annotation.isKindOfClass(MKUserLocation) { 
     return nil 
    } 

    let detailButton: UIButton = UIButton(type: UIButtonType.DetailDisclosure) 

    // Reuse the annotation if possible 
    var annotationView = mapView.dequeueReusableAnnotationViewWithIdentifier(identifier) 

    if annotationView == nil 
    { 
     annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "pin") 
     annotationView!.canShowCallout = true 
     annotationView!.image = UIImage(named: "VRtest.png") 
     annotationView!.rightCalloutAccessoryView = detailButton 
     print("editing annotation") 
    } 
    else 
    { 
     annotationView!.annotation = annotation 
    } 

    return annotationView 
} 

Jede Hilfe ist willkommen. danke

Was möchten Sie die Standardannotation anpassen? Wenn ja, können Sie diesen Beitrag verweisen How to create Custom MKAnnotationView and custom annotation title and subtitle

Hier ist das Beispiel in Swift 2

class MapViewController: UIViewController { 


    @IBOutlet weak var mapView: MKMapView! 

    let initialLocation = CLLocation(latitude: 34.074094, longitude: -118.396329) 
    let regionRadius: CLLocationDistance = 1000 

    func centerMapOnLocation(location: CLLocation) { 
     let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate, 
      regionRadius * 2.0, regionRadius * 2.0) 
     self.mapView.setRegion(coordinateRegion, animated: true) 
    } 

    override func viewDidLoad() { 
     self.mapView.delegate = self 
     self.centerMapOnLocation(initialLocation) 

     let location = CLLocationCoordinate2D(latitude: 34.074094, longitude: -118.396329) 
     let annotation = CustomAnnotation(coordinate: location, imageName: "pinIcon", title: "Test", subtitle: "Detail", enableInfoButton: false) 

     self.mapView.addAnnotation(annotation); 
    } 
} 

extension MapViewController: MKMapViewDelegate { 
    func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? { 

     if (annotation is MKUserLocation) { 
      return nil 
     } 

     let pinIdentifier = "pinIdentifier" 
     var view: MKAnnotationView 
     if (annotation.isKindOfClass(CustomAnnotation)) { 
      if let dequeuedView = mapView.dequeueReusableAnnotationViewWithIdentifier(pinIdentifier) 
       as MKAnnotationView? { 
        dequeuedView.annotation = annotation 
        view = dequeuedView 
      } else { 
       view = MKAnnotationView(annotation: annotation, reuseIdentifier: pinIdentifier) 
       view.canShowCallout = true 

       //Set custome image 
       let customAnnotation = annotation as! CustomAnnotation 
       view.image = UIImage(named:customAnnotation.imageName!) 
      } 

      return view 
     } 

     return nil 
    } 

} 

class CustomAnnotation : NSObject, MKAnnotation { 

    var coordinate: CLLocationCoordinate2D 
    var imageName: String? 
    var title: String? 
    var subtitle: String? 
    var enableInfoButton : Bool 

    init(coordinate: CLLocationCoordinate2D, imageName: String, title: String, subtitle: String, enableInfoButton : Bool) { 
     self.coordinate = coordinate 
     self.imageName = imageName 
     self.title = title 
     self.subtitle = subtitle 
     self.enableInfoButton = enableInfoButton; 
    } 
}
