Objective C

For a block callback on didChangeAuthorizationStatus add this in .h

@property void(^authorizationCompletionBlock)(BOOL);

and following in .m

-(void)locationManager:(CLLocationManager *)locationManager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
_authorizationStatus = status;

switch (status) {
    case kCLAuthorizationStatusAuthorizedAlways:
    case kCLAuthorizationStatusAuthorizedWhenInUse:
        if (self.authorizationCompletionBlock) {
            self.authorizationCompletionBlock(YES); // this fires block
        }
    default:
        if (self.authorizationCompletionBlock) {
            self.authorizationCompletionBlock(NO); // this fires block
        }
        break;
    }
}

and add handler like this:

// this listens block
// in your VC or Utility class
authorizationCompletionBlock = ^(BOOL isGranted) {
    completionBlock(isGranted);
};

Swift 3.2

var authorizationCompletionBlock:((Bool)->())? = {_ in}


func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    switch (status)
    {
    case (.authorizedWhenInUse):
        if authorizationCompletionBlock != nil
        {
            authorizationCompletionBlock!(true)
        }

    default:
        if authorizationCompletionBlock != nil
        {
            authorizationCompletionBlock!(false);
        }
    }
}

and handler like this

authorizationCompletionBlock = { isGranted in
        print(isGranted)
    }
