I'm currently using the following code to position the camera on my Google Map:
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:49.282237
longitude:-123.125966
zoom:13];
mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
Instead of having the camera zoom in to those coordinates, how can I get it to zoom in to a user's current location? I can't seem to sort out that code; any help would be appreciated.
