How to update location using Google Maps SDK - ios

Question

I am using Google Maps SDK to get the current location. My doubt is, how to do location updates using the delegate methods using Google Maps SDK. Is there any delegate methods for getting the current location and location updates?
#implementation MyLocationViewController {
GMSMapView *mapView_;
}
- (void)viewDidLoad {
[super viewDidLoad];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.868 longitude:151.2086 zoom:12];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.settings.compassButton = YES;
mapView_.settings.myLocationButton = YES;
// Listen to the myLocation property of GMSMapView.
[mapView_ addObserver:self forKeyPath:#"myLocation"
options:NSKeyValueObservingOptionNew context:NULL];
self.view = mapView_;
// Ask for My Location data after the map has already been added to the UI.
dispatch_async(dispatch_get_main_queue(), ^{
mapView_.myLocationEnabled = YES;
});
}

You can use CLLocationManager delegate methods to update location and set the location to the map.
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations;
This delegate method will update the location. Inside the method, you can set the map view to the coordinates received.
_currentLocation = [locations lastObject];
CLLocationCoordinate2D target =
CLLocationCoordinate2DMake(_currentLocation.coordinate.latitude, _currentLocation(This is the current location of the user).coordinate.longitude);
_googleMap.camera = [GMSCameraPosition cameraWithTarget:target zoom:16];
