Question

我正在使用此代码尝试检查设备的Apple Music功能：

  SKCloudServiceController *controller = [SKCloudServiceController new];
  [controller requestCapabilitiesWithCompletionHandler:^(SKCloudServiceCapability capabilities, NSError * _Nullable error) {
    if (error != nil) {
      NSLog(@"Error getting SKCloudServiceController capabilities: %@", error);
    } else if (capabilities & SKCloudServiceCapabilityMusicCatalogPlayback) {
      NSLog(@"YES SUBSCRIBED!!!!");
    } else {
      NSLog(@"NOT SUBSCRIBED!!!!");
    }
  }];

很遗憾，我无法追踪如何解决我收到的错误。

我认为SKCloudServiceController正在本地查找设备功能，因此无需连接到Apple即可确定

。

那么为什么错误使我相信SKCloudServiceController在连接到Apple时出现某种通讯问题？

以下是显示错误的时间剥离输出日志：

[core] "Error returned from daemon: Error Domain=com.apple.accounts Code=9 "(null)""
SSAccountStore: Failed to fetch the backing accounts. error = Error Domain=com.apple.accounts Code=9 "(null)"

谢谢您的帮助：）

P.S。我确实记得要在项目中添加StoreKit功能，并将其头文件导入运行我的代码的.m文件中。
