iOS locationmanager didChangeAuthorizationStatus未从kCLAuthorizationStatusDenied调用到kCLAuthorizationStatusAuthorized状态

Question

在设置应用程序>隐私>位置服务>我的应用程序>从不在后台模式下,didChangeAuthorizationStatus被称为kCLAuthorizationStatusDenied状态.但在更改"Always"之后,未调用didChangeAuthorizationStatus.关闭"位置服务"时也不会调用.

我在Info.plist中插入了NSLocationAlwaysUsageDescription并设置了位置更新后台模式.

我的代码,

- (id)init {
    self = [super init];
    if (self) {       
        _locationManager = [[CLLocationManager alloc] init];
        _locationManager.delegate = self;
        _locationManager.pausesLocationUpdatesAutomatically = NO;

        if ([_locationManager respondsToSelector:@selector(setAllowsBackgroundLocationUpdates:)]) {
            NSLog(@"setAllowsBackgroundLocationUpdates");
            _locationManager.allowsBackgroundLocationUpdates = YES;
        }

        [self requestAuthorization];
    }
    return self;
}

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
    NSLog(@"CLAuthorizationStatus: %d", status);
}

对不起我的英文.

我遇到了这个确切的问题,事实证明我正在制作我的CLLocationManager电话

-requestWhenInUseAuthorization

在背景线程上.我在主线程上调用了这些方法并获得了预期的结果(-locationManager:didChangedAithorizationStatus:在我点击"不允许"或"允许"后调用)
