推荐答案

`first get all points coordinates which are coming in route then add these points latitude and longitude in path in will draw path according to that`


GMSCameraPosition *cameraPosition=[GMSCameraPosition cameraWithLatitude:18.5203 longitude:73.8567 zoom:12];
_mapView =[GMSMapView mapWithFrame:CGRectZero camera:cameraPosition];
_mapView.myLocationEnabled=YES;
GMSMarker *marker=[[GMSMarker alloc]init];
marker.position=CLLocationCoordinate2DMake(18.5203, 73.8567);
marker.icon=[UIImage imageNamed:@"aaa.png"] ;
marker.groundAnchor=CGPointMake(0.5,0.5);
marker.map=_mapView;
GMSMutablePath *path = [GMSMutablePath path];   
[path addCoordinate:CLLocationCoordinate2DMake(@(18.520).doubleValue,@(73.856).doubleValue)];
[path addCoordinate:CLLocationCoordinate2DMake(@(16.7).doubleValue,@(73.8567).doubleValue)];

GMSPolyline *rectangle = [GMSPolyline polylineWithPath:path];
rectangle.strokeWidth = 2.f;
rectangle.map = _mapView;
self.view=_mapView;
