Answer 1

Write this code :

[locationManager startUpdatingLocation];

& write their delegates methods also :

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
   NSMutableString *latString = [NSMutableString stringWithFormat:@"%f",newLocation.coordinate.latitude];

   NSMutableString *lngString = [NSMutableString stringWithFormat:@"%f",newLocation.coordinate.longitude];
}
