GMSMapView跟踪模式标题

Question

In my app, I am using GMSMapView , and I would like to change tracking mode. In iOS MapKit, I can change the tracking mode to MKUserTrackingModeFollowWithHeading , but don't know how to change it in GMSMapView .

In the app Google Maps , it is working after second touch on myLocationButton . Is it possible?

For continuously changing the camera with the current location, you will need to update the GMSCamera for google maps to current location. You can do it in Location Manager delegate method.

CLLocation *location;

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
//Get current latitude and longitude from didUpdateLocation
    location = [locations lastObject];
}



-(void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading
{
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:location.coordinate.latitude longitude:location.coordinate.longitude zoom:10 bearing:newHeading.trueHeading viewingAngle:0];
//You can change viewingAngle from 0 to 45
    [self.mapForView animateToCameraPosition:camera];
}

In case your delegate is not getting called, take help from my answer here
