MapKit

Question

我正在尝试更改图钉颜色，但是当我添加代码以切换注释时，它还会更改我的位置图标（从蓝点变为图钉）。关于如何恢复默认用户位置图标的任何提示？

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
    let annotationView = MKMarkerAnnotationView(annotation: annotation, reuseIdentifier: "MyMarker")
    switch annotation.title!! {
        case "Ślęża":
            annotationView.markerTintColor = UIColor(red: (69.0/255), green: (95.0/255), blue: (170.0/255), alpha: 1.0)
        case "Śnieżnik":
            annotationView.markerTintColor = UIColor(red: (52.0/255), green: (114.0/255), blue: (1.0/255), alpha: 1.0)
        case "test":
            annotationView.markerTintColor = UIColor(red: (246.0/255), green: (233.0/255), blue: (212.0/255), alpha: 1.0)
        case "Brooklyn Bridge":
            annotationView.markerTintColor = UIColor(red: (146.0/255), green: (187.0/255), blue: (217.0/255), alpha: 1.0)
        default:
            annotationView.markerTintColor = UIColor.blue
    }
    return annotationView
}

添加检查以排除它

guard !(annotation is MKUserLocation) else { return nil }
let annotationView = MKMarkerAnnotationView(annotation: annotation, reuseIdentifier: "MyMarker")
