SSAccountStore：无法获取本地帐户。错误=错误域=SSErrorDomain代码=100

Question

我无法访问用户 Apple Music。我得到的错误是

 [core] "Error returned from daemon: Error Domain=com.apple.accounts Code=9 "(null)""
2019-02-04 19:14:37.250467+0900 SSAccountStore: Failed to fetch the backing accounts. error = Error Domain=com.apple.accounts Code=9 "(null)"
2019-02-04 19:14:37.252008+0900 [core] "Error returned from daemon: Error Domain=com.apple.accounts Code=9 "(null)""
2019-02-04 19:14:37.252051+0900  SSAccountStore: Failed to fetch the backing accounts. error = Error Domain=com.apple.accounts Code=9 "(null)"
2019-02-04 19:14:37.253604+0900  SSAccountStore: Unable to get the local account. error = Error Domain=SSErrorDomain Code=100 "Cannot connect to iTunes Store" UserInfo={NSLocalizedDescription=Cannot connect to iTunes Store}

然而，这段代码的奇怪部分是我还能够检索音乐用户令牌。有什么我想念的吗？任何帮助表示赞赏。

    static func auth(){
        let cloudServiceController = SKCloudServiceController()

        let developerToken = "abcdefghijklmnopqrstuvwxyz abcdefghijklmnopqrstuvwxyabcdefghijklmnopqrstuvwxyz"


        SKCloudServiceController.requestAuthorization { status in
            guard status == .authorized else { return }
        }

        cloudServiceController.requestCapabilities { capabilities, error in
            guard capabilities.contains(.musicCatalogPlayback) else { return }
        }

        cloudServiceController.requestUserToken(forDeveloperToken: developerToken, completionHandler: { token, error in

            guard let token = token else { return }
            UserDefaults.standard.set(token, forKey: "MUSIC_USER_TOKEN")
            UserDefaults.standard.set(developerToken, forKey: "DEVELOPER_TOKEN")
            print("Music User Token:", token)
        })
    }

我认为您必须 cloudServiceController.requestUserToken 在用户授权完成处理程序后调用SKCloudServiceController.requestAuthorization
