Question

作为iOS Swift开发的新手，我想知道是否有人可以帮助我了解针对身份验证错误（例如，错误的用户名和密码）自定义客户端警报消息的正确方法。下面是默认警报消息，该消息以异常名称作为标题，这不是良好的用户体验。如何显示带有其他标题和消息的警报弹出窗口？

我认为您正在寻找UIAlertController。

快速示例：

let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: UIAlertController.Style.alert)
let alertAction = UIAlertAction(title: "OK!", style: UIAlertAction.Style.default)
        {
            (UIAlertAction) -> Void in
        }
        alert.addAction(alertAction)
        present(alert, animated: true)
        {
            () -> Void in
        }

希望有帮助！

处理您的错误响应以定义自定义标题和消息，例如下面。

import AWSCognitoIdentityProvider

extension Error {
    var customizedDescription: String {
        let nsError = self as NSError
        if nsError.domain == AWSCognitoIdentityProviderErrorDomain, let code = AWSCognitoIdentityProviderErrorType(rawValue: nsError.code) {
            switch code {
            case .expiredCode: return "Verification code has expired. Please try again"
            case .codeMismatch: return  "Incorrect verification code. Please enter the correct code to continue."
            case .notAuthorized: return "Authentication failed. Please enter the correct credentials to continue."
            case .usernameExists: return "Username already exists."
            case .invalidPassword: return "Invalid password. Please try again."
            case .userNotConfirmed: return "User not confirmed. Please verify your account."
            default: return nsError.userInfo["message"] as? String ?? "AWS cognito failed with error code: \(nsError.code)"
            }
        }
        return localizedDescription
    }
}
