LocationManager didUpdateToLocation always check for change in location. If it fing multiple location it will call multiple time. You can avoid it in different way. But this will not update the location if user changes his current place.
You can user this code just to get location and proceed further.
-(void)getLocation{
locationManager = [[CLLocationManager alloc] init] ;
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
// [locationManager startUpdatingLocation]; commented to avoid multiple calling or you can say updating current location
CLLocation *newLocation=[locationManager location];
CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
[geoCoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) {
NSString * location = ([placemarks count] > 0) ? [[placemarks objectAtIndex:0] locality] : #"Not Found";
NSLog(#"location:%#",location);
NSLog(#"lat:%f",locationManager.location.coordinate.latitude);
NSLog(#"long:%f",locationManager.location.coordinate.longitude);
}];
}
