CLLocation Manager Delegates Not Called?

Question

나는 현재 위치를 얻기위한 하나의 데모를 만들었습니다. 현재 위치에 .GPX 파일을 사용했습니다. CLLocation 메서드의 Delegates 메서드를 사용했습니다.

필자의 plist 파일에서도 Key "Privacy - Location When In Use Usage Description"을 사용했습니다.

이 질문은 이미 많은 시간을 요구했지만 결과를 얻을 수 없다는 것을 알고 있습니다.

코드는 메소드가 호출되지 location.Because 위임을 얻을 수

도움말 저 녀석이 아니다.

항상이 방법을 호출했습니다.

위치의 허가를 확인해야합니다. 그런 다음 대리인 메서드를 호출 할 수 있습니다.

- (void)viewDidLoad { 

    [super viewDidLoad]; 

    locationManager=[[CLLocationManager alloc] init]; 
    locationManager.delegate = self; 
    locationManager.distanceFilter = kCLDistanceFilterNone; 
    locationManager.desiredAccuracy = kCLLocationAccuracyBest; 
    [locationManager startUpdatingLocation]; 

    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) 
    { 
     [locationManager requestWhenInUseAuthorization]; 
    } 
    if ([CLLocationManager locationServicesEnabled]){ 

     NSLog(@"Location Services Enabled"); 

     if ([CLLocationManager authorizationStatus]==kCLAuthorizationStatusDenied){ 
      alert = [[UIAlertView alloc] initWithTitle:@"Permission Denied" 
               message:@"To re-enable, please go to Settings and turn on Location Service for this app." 
               delegate:nil 
            cancelButtonTitle:@"OK" 
            otherButtonTitles:nil]; 
      [alert show]; 
     } 
    } 
} 
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation 
{ 
    CLLocation *currentLocation = newLocation; 
    txtlocations.text = [NSString stringWithFormat:@"%f & %f",currentLocation.coordinate.latitude, currentLocation.coordinate.longitude]; 
}

약간의 변경 및 작동으로 코드를 사용해 보았습니다.

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view, typically from a nib. 
    [self updateCurrentLocation]; 
} 

- (void)updateCurrentLocation { 

    if([CLLocationManager locationServicesEnabled] && 
     [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied) { 
     locationManager = [[CLLocationManager alloc] init]; 
     locationManager.delegate=self; 
     locationManager.desiredAccuracy=kCLLocationAccuracyBest; 
     locationManager.distanceFilter=kCLDistanceFilterNone; 
     [locationManager requestWhenInUseAuthorization]; 
     [locationManager startMonitoringSignificantLocationChanges]; 
     [locationManager startUpdatingLocation]; 
     // show the map 
    } else { 
     // show error 



    } 
}
