圈覆蓋我遇到了一個錯誤:收到錯誤嘗試應用在迅速3
不能調用類型「MKCircle」初始型中心「(參數列表:CLLocationCoordinate2D,半徑:INT,標識符:字符串)」
let region = CLCircularRegion(coder: MKCircle(center: CLLocationCoordinate2DMake(self.destLat!, self.destLong!), radius: 100, identifier: destinationAddress))
self.locationManager .startMonitoring(for: region)
下面是我ovelay方法
func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
if overlay is MKCircle {
let circleRenderer = MKCircleRenderer(overlay: overlay)
circleRenderer.lineWidth = 1.0
circleRenderer.strokeColor = .purple
circleRenderer.fillColor = UIColor.purple.withAlphaComponent(0.4)
return circleRenderer
}
let myLineRenderer = MKPolylineRenderer(polyline: myRoute.polyline)
myLineRenderer.strokeColor = UIColor.blue
myLineRenderer.lineWidth = 3
return myLineRenderer
}
我想要在該位置應用圓形覆蓋圖,我該怎麼做? –
