AWS cognito 示例应用程序的问题

Question

我正在尝试从 https://github.com/awslabs/aws-sdk-ios-samples/tree/master/CognitoSync-Sample/Swift 运行此 AWS cognito 示例应用程序。我可以添加新的数据集，但是一旦我尝试同步/刷新，就会出现以下错误。我没有尝试与任何提供商合作。只是简单的数据同步。

这是我做的步骤-

1.从github下载示例应用。

2.使用给定的 pod 安装 AWSCognito

3.并在 Amazon cognito 控制台中创建了一个身份池

4. 并更新了 Constants.swift 中的常量 -

静态让 COGNITO_REGIONTYPE = AWSRegionType.USEast1 静态让 COGNITO_IDENTITY_POOL_ID = "us-east-1_XXXXXXXXX"

这是来自我的控制台的错误 -

我错过了什么？我对 AWS 服务非常陌生，非常感谢任何指导。

谢谢， 里查

Answer 1

我使用的是用户池 ID，而不是身份池 ID。现在解决了。

Answer 2

是的，这几乎总是使用用户池 ID 而不是身份池。

请注意，如果您在初始化 AWSCognitoCredentialsProvider() 时输入了正确的身份池 ID，它将在模拟器中工作，即使您的 info.plist AWS 字典描述符中的 ID 错误。但在设备上，它将使用 info.plist 池 ID，如果错误则失败。这让我有点吃惊，所以请确保您的泳池 ID 在两个位置都是正确的。
