Google Maps iOS Remove Polylines

Question

Is it possible to remove all Polylines without removing other objects?

[mapView clear]; removes everything including markers

I also tried the following but it didn't work either..

for (GMSPolyline __strong *polyline in self.mapView.subviews) {
    polyline = nil;
}

Thanks in advance

PS : I am using Google Maps SDK for iOS version: 1.7.2.7908

Answer 1

When you add the polylines you should add them to your own collection. Then when you need to remove them, loop over your own collection and set each polyline's .map property to nil (which removes it from the map).

Answer 2

You have to do

[self.polyline setMap:nil];

, that will remove the line from the map.
