Getting Longitude/Latitude of the User When the viewDidLoad

My purpose is to get the longitude/latitude of the user when the view is loaded and to store the values in two variables for later calculations. I don't need to track the user location and to update it, I simply need to get his/her coordinates once. My code looks like this:

- (void)viewDidLoad {
[super viewDidLoad];
// locationManager update as location
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
CLLocation *location = [locationManager location];
// Configure the new event with information from the location
CLLocationCoordinate2D coordinate = [location coordinate];

float longitude=coordinate.longitude;
float latitude=coordinate.latitude;

NSLog(@"dLongitude : %f",longitude);
NSLog(@"dLatitude : %f", latitude);
}


In the console i keep getting this:

dLongitude : 0.000000
dLatitude : 0.000000


Can you please help me there?

Answer

To get user's location even once you need to make locationManager to start updating locations (you did that) and implement delegate method that manager calls when location is retrieved - you can't get location from location manager immediately.

If you don't want to track user location - just stop updating locations in that delegate method after location was fetched for the 1st time (and store it if you need it in future).
