Objective-C - Core Location - iOS 7.1 - ios

Question

I have a code in a UIViewController that starts the location update:
[locationManager startUpdatingLocation];
Is working perfectly. But I need every time you exit this screen it stops updating the location and start again when I return.
The first time it for updates. In other times it does not stop.
Code for exit from view:
[locationManager stopUpdatingLocation];
locationManager.delegate = nil;
Ihave tried also: (without success too)
[locationManager stopMonitoringSignificantLocationChanges];
[locationManager stopUpdatingHeading];
[locationManager stopUpdatingLocation];
locationManager.delegate = nil;
locationManager = nil;
It always update. But from the second time not stop update.
didUpdateLocation code:
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
[self addingMarkerUser];
}

Answer 1

You should put your code in the viewDidAppear and i suppose in your [self addingMarkerUser] you use something like this without the stop (if not, please provide the code) :
CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
[geocoder reverseGeocodeLocation:_currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
if (!(error)) {
//do something with the data.
//then stop the update.
[locationManager stopUpdatingLocation];
}
}];
If you do like that, every time your view appear, the location will start the update then stop once the data retrieve.
