How to get current zoom level from google map for ios? -

i use method camera digital value this:

camera = [gmscameraposition camerawithlatitude:37.35 longitude:-122.0 zoom:6]; 

and need automatically redraw map current position via timer:

-(void)gmapredraw{     nslog(@"gmapredraw"); //    self.mapview.camera     [locationmanager startupdatinglocation];     nslog(@"lat %f, lon %f", locationmanager.location.coordinate.latitude, locationmanager.location.coordinate.longitude);     camera = [gmscameraposition camerawithlatitude:locationmanager.location.coordinate.latitude//37.36//-37.81319//-33.86                                          longitude:locationmanager.location.coordinate.longitude//-122.0//144.96298//151.20                                               zoom:6];     self.mapview.camera = camera; }  -(void)timer{     [nstimer scheduledtimerwithtimeinterval:0.5                                      target:self                                    selector:@selector(gmapredraw)                                    userinfo:nil                                     repeats:yes]; } 

but how can current zoom if change via touch?

ok, find solution, current zoom:

cgfloat currentzoom = self.mapview.camera.zoom; 

and use in camera:

camera = [gmscameraposition camerawithlatitude:locationmanager.location.coordinate.latitude                                      longitude:locationmanager.location.coordinate.longitude                                           zoom:currentzoom]; self.mapview.camera = camera;
