如何自定义MKPolyLineView以绘制不同的样式线

import MapKit

class CustomMKPolylineView: MKPolylineView {
    override init(frame: CGRect) {
        super.init(frame: frame)
        self.configure()
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        self.configure()
    }
    
    func configure() {
        self.strokeColor = UIColor.blue
        self.lineWidth = 5
        self.lineCap = .round
        self.lineJoin = .round
        self.alpha = 0.5
    }
}

let polyline = MKPolyline(coordinates: coordinates, count: coordinates.count)
let polylineView = CustomMKPolylineView(polyline: polyline)
mapView.addOverlay(polyline)
