swift - SSAccountStore : Unable to get the local account. 错误 = 错误域 = SSErrorDomain 代码 = 100

Question

我在访问用户 Apple Music 时遇到问题。我收到的错误是

 [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}

但是这段代码的奇怪部分是我还能够检索音乐用户 token 。我缺少什么吗？如有任何帮助，我们将不胜感激。

    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)
        })
    }

我想你必须打电话cloudServiceController.requestUserToken一旦用户在 SKCloudServiceController.requestAuthorization

的完成处理程序后获得授权
