您想要自定义默认注释？如果是，您可以参考此帖How to create Custom MKAnnotationView and custom annotation title and subtitle

以下是Swift 2中的示例

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;
    }
}

这是我在屏幕上显示的自定义图像
