Get latitude and longitude of current location

Add core location framework and import them.

Now in .h file add delegate CLLocationManagerDelegate.

CLLocationManager *locationManager;

    double current_lati;

    double current_longi;

In .m class

-(void)getCurrentLatLon

{

    

    // 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

    current_lati = location.coordinate.latitude;

    current_longi = location.coordinate.longitude;

    

    NSLog(@"dLongitude : %f", current_longi);

    NSLog(@"dLatitude : %f", current_lati);
