Is it possible to show overlay in cluster?

[zhouhao27]

I'd like to know if it's possible to show overlays like MKCircle in cluster? Thanks.

Yes. Not in cluster but in MapView. Cluster and MKCircle both are different thing. You need to Use

func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer

method.

Here is sample code,

    func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
        if overlay is MKCircle {
                 let circle = MKCircleRenderer(overlay: overlay)
                 circle.strokeColor = UIColor.red
                 circle.fillColor = UIColor.red.withAlphaComponent(0.5)
                 circle.lineWidth = 1
                 return circle
             }
       else {
            guard let tileOverlay = overlay as? MKHipsterTileOverlay
                else {
                    return MKOverlayRenderer()
            }
            return MKTileOverlayRenderer(tileOverlay: tileOverlay)
        }
    }
