Question

我有一个自定义类，我可以在其中添加区分该类型的变量“type”，这是更改图标的选项，但我不知道我可以在哪里制作更改图标，我试图在方法mapView没有得到结果导入UIKit 导入CoreData 导入MapKit

    class MKAnnotationCostum: NSObject, MKAnnotation{

        var coordinate :  CLLocationCoordinate2D
        var title :  String?
        var subtitle :  String?
        var tipo:String?
        var image: UIImage?

        init ( coordinate :  CLLocationCoordinate2D , title :  String , subtitle :  String, tipo:String )  {
            self.coordinate = coordinate
            self.title = title
            self.subtitle = subtitle
            self.tipo = tipo
        }
    }

我希望根据tipo获得一个不同的图像

    @IBOutlet weak var myMap: MKMapView!

    override func viewDidLoad() {
        super.viewDidLoad()

            myMap.delegate =  self
        }
    override func viewDidAppear(animated: Bool) {
      super.viewDidAppear(animated)


        let request =  NSFetchRequest(entityName: "PUNTO")
        if let results = try? context.executeFetchRequest(request) {
            for resultado in results {

                let latitud:CLLocationDegrees = Double(resultado.valueForKey("puntoLatitud") as! NSNumber)
                let longitud:CLLocationDegrees = Double(resultado.valueForKey("puntoLongitud") as! NSNumber)

                let lateDelta:CLLocationDegrees = 0.01

                let span: MKCoordinateSpan = MKCoordinateSpanMake(lateDelta, longDelta)
                let location:  CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitud,longitud)

                let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)


                myMap.setRegion(region, animated: true)

//                pointAnnotation.title  =  String(resultado.valueForKey("puntoDireccion")!)

               print("color: \(pointAnnotation.tipo)")

                   myMap.addAnnotation(pointAnnotation)

            }
            else {

            }

            return anotacionView
        }

        let reusarId = "anotacion"

        }else {
