CLLocationManager stopUpdatingLocation when address is obtained, but address label is still empty - iphone

Question

I got an app that shows current location on some labels. In viewDidLoad I call [gps startUpdatingLocation]; (instance of CLLocationManager), so gps calls the relative method:
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
//NSLog(#"didUpdateToLocation: %#", newLocation);
currentLocation = newLocation;
if (currentLocation != nil) {
longitude.text = [NSString stringWithFormat:#"%.3f", currentLocation.coordinate.longitude];
latitude.text = [NSString stringWithFormat:#"%.3f", currentLocation.coordinate.latitude];
}
NSLog(#"Resolving the Address");
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
NSLog(#"Found placemarks: %#, error: %#", placemarks, error);
if (error == nil && [placemarks count] > 0) {
placemark = [placemarks lastObject];
[address sizeToFit];
address.text = [NSString stringWithFormat:#"%#, %#\n%# %#\n%#",
[self sanitizedDescription:placemark.thoroughfare],
[self sanitizedDescription:placemark.subThoroughfare],
[self sanitizedDescription:placemark.postalCode],
[self sanitizedDescription:placemark.locality],
[self sanitizedDescription:placemark.country]];
if (address.text != NULL)
{
[gps stopUpdatingLocation];
}
} else {
NSLog(#"%#", error.debugDescription);
}
} ];
}
So when the address is obtained, gps must stopUpdatingLocation. All works fine, but in-app address label is still empty! Why?
P.S.: sanitizedDescription is a simple method that returns "..." if a placemark.value is nil:
- (id)sanitizedDescription:(NSString *)obj
{
if (obj == nil)
{
obj = #"...";
return obj;
}
return obj;
}

Problem solved, address label was too small, so I simply called [address sizeToFit] again in the if cycle:
if (address.text != NULL)
{
[address sizeToFit];
[gps stopUpdatingLocation];
}
