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

Question

I use method camera with digital value like this:

camera = [GMSCameraPosition cameraWithLatitude:37.35 longitude:-122.0 zoom:6]; 

and I need automatically redraw map with 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 I can get current zoom if I change it via touch?

Answer 1

OK, I find solution, get current zoom:

CGFloat currentZoom = self.MapView.camera.zoom; 

and then use it in camera:

camera = [GMSCameraPosition cameraWithLatitude:locationManager.location.coordinate.latitude                                      longitude:locationManager.location.coordinate.longitude                                           zoom:currentZoom]; self.MapView.camera = camera;
