可调整大小的GMSCircle适用于iOS的GoogleMaps SDK

有什么方法调整（缩小和展开）GMSCircle对象吗？我创建GMSCircle并将其附加到我们的地图可调整大小的GMSCircle适用于iOS的GoogleMaps SDK

var cirlce: GMSCircle! 

let camera = GMSCameraPosition.cameraWithLatitude(-33.86, longitude: 151.20, zoom: 6) 
mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera) 

cirlce = GMSCircle(position: camera.target, radius: 100000) 
cirlce.fillColor = UIColor.redColor().colorWithAlphaComponent(0.5) 
cirlce.map = mapView

我要让circle回应我的手势来调整，并得到其圆的半径值。例如，它有一个网络版here。

那么如何创建？任何帮助，将不胜感激。谢谢！

嘿，你有没有找到任何解决方案？ – Apple

@苹果还没有找到任何解决方案，然后我只是创建滑块为圆的半径值。 –

是否可以移动和调整地图中的圆圈？我对此有怀疑..因为我仍然无法找到与之相关的任何解决方案。如果你有任何想法，那么我发布了一个问题http://stackoverflow.com/questions/40991640/resize-drag-and-scale-gmscircle-in-google-map-objective-c请做回复。 – Apple

func mapView(_ mapView: GMSMapView, didChange position: GMSCameraPosition) {

//This is the Slider function to zoom in and out by Slider on View Controller 
@IBAction func cricleZoom(_ sender: Any) { 
    cirlce.radius = CLLocationDistance(sliderer.value)
