Getting user's current location iOS 8.0

Question

I trying to get users current location using MapKit and CoreLocation. I\'m really new to Objective-C. As for my research the implementation is slightly different from older iOS

Answer 1

Your flow for requesting and starting location update is not proper. First of all the requestAlwaysAuthorization will not change the authorization status immediately because it needs user to press Allow or Don't Allow button in the alert. So you should start location update only after getting its result. Then in didUpdateLocations no need to request/start again.

Do it in following way,

Dn your viewDidLoad

 BOOL isAuthorized = [CLLocationManager authorizationStatus] == kCLAuthorizationStatusAuthorizedAlways;
 if (isAuthorized) {
     [locationManager startUpdatingLocation];
 }
 else {
     [locationManager requestAlwaysAuthorization];
 }

And implement the delegate methods like

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
   CLLocation *current = locations.firstObject;
}

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{
    if(status == kCLAuthorizationStatusAuthorizedAlways || status == kCLAuthorizationStatusAuthorizedWhenInUse){
        self.serviceLocation.showsUserLocation = YES;
       [locationManager startUpdatingLocation];
    }
}

In iOS 8 for requesting permission you should add the usage description string in the info.plist. In your case the key is NSLocationAlwaysUsageDescription.
