外围设备包括服务 - iOS

Question

我有一个应用程序，它扮演外围角色并使用 CoreBluetooth 框架启动广告。我成功添加了一个服务并对其进行了广告，并使用另一个Central应用程序成功发现了它。

但是，当我想向我的主服务添加一些辅助服务时，其他中央应用程序不会发现它们。

在外围设备上，我将服务添加到CBPeripheralManager对象：

- (void)AddService:(BOOL )primary {
    CBMutableService *Service = [[CBMutableService alloc] initWithType:_service_UUID primary:primary];
    if (primary)
        _mainService = Service;

    NSMutableArray *characteristics = [[NSMutableArray alloc] init];
    for (MyCharacterstic *characteristic in _service_characteristics)
        [characteristics addObject: [characteristic GetObject]];
    Service.characteristics = characteristics;
    [_manager addService: Service];
}

- (void)peripheralManager:(CBPeripheralManager *)peripheral didAddService:(CBService *)service error:(NSError *)error {
    if (!service.isPrimary)
        [_services addObject:service];
}

添加完所有辅助服务后，我调用以下函数开始播放：

- (void)StartAdvertisement {
    _mainService.includedServices = _services;
    [_manager startAdvertising:@{CBAdvertisementDataLocalNameKey: _LocalName,
                                 CBAdvertisementDataServiceUUIDsKey: @[_mainService.UUID]}];
}

在中心端，我尝试发现所包含的服务：

- (void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(NSError *)error {
    for (CBService *service in peripheral.services) {
        if ([_service_UUID containsObject: service.UUID]) {
            [peripheral discoverCharacteristics:nil forService:service];
            [peripheral discoverIncludedServices:nil forService:service];
        }
    }
}

它调用以下委托函数，但它总是为包含的服务返回一个空数组：

- (void)peripheral:(CBPeripheral *)peripheral didDiscoverIncludedServicesForService:(CBService *)service error:(NSError *)error {
     for (CBService *services in service.includedServices) {
         NSLog(@"Service: %@", services);
     }
}
