Question

How to cusomize the polylines on google maps ?

Now I'm doing like in the documentation:

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_;

But I need to give some effect to line (say glow effect).

How to realise this?

Thank you

Right now you can only set colors or gradients (transition between two colors), optionally with alpha (transparency) for polylines. See https://developers.google.com/maps/documentation/ios/shapes#polylines

There is no glow or other effect for polylines.
