Google Maps SDK for iOS -Polyline

Question

如何在google地图上定义折线？

现在，我正在执行文档中的操作：

GMSMutablePath *path = [GMSMutablePath path];
[path addCoordinate:CLLocationCoordinate2DMake(37.36, -122.0)];
[path addCoordinate:CLLocationCoordinate2DMake(37.45, -122.0)];
[path addCoordinate:CLLocationCoordinate2DMake(37.45, -122.2)];
[path addCoordinate:CLLocationCoordinate2DMake(37.36, -122.2)];
[path addCoordinate:CLLocationCoordinate2DMake(37.36, -122.0)];

GMSPolyline *polyline = [GMSPolyline polylineWithPath:path];
polyline.strokeColor = [UIColor greenColor];
polyline.strokeWidth = 10.f;
polyline.geodesic = YES;

polyline.map = mapView_;

但是我需要给线条一些效果(比如发光效果)。

如何实现这一点？

谢谢

现在，您只能设置颜色或渐变(两种颜色之间的过渡)，也可以选择为折线设置alpha (透明度)。请参阅https://developers.google.com/maps/documentation/ios/shapes#polylines

多段线没有光晕或其他效果。
