How to delete the shape(circle) on google map when tap on marker?

问题

I can add many markers and circles on google map with in "didTapAt" event, but I want to delete them as well, for markers I can do this in "didTap marker" event but how can I delete its shape not other shape?

回答1:

let circle = GMSCircle(position: CLLocationCoordinate2D(latitude: 40.7336299, longitude: 30.1616061, radius: 10)
 circle.isTappable = true
 circle.map = mapView

func mapView(_ mapView: GMSMapView, didTap overlay: GMSOverlay) {
    overlay.map = nil
}
