我正在尝试在使用 AWS Cognito 的 iOS 应用程序上实现响应 FORCE_CHANGE_PASSWORD 的功能。我使用了这个 Stack Overflow 问题，它引用了这个示例代码。现在，我的代码打开了一个视图控制器，就像它应该的那样；但是，一旦在该视图控制器上，我就无法让它做任何事情。在示例代码中，似乎当您想提交.set对 的实例调用的密码更改请求AWSTaskCompletionSource<AWSCognitoIdentityNewPasswordRequiredDetails>时，但是当我这样做时，didCompleteNewPasswordStepWithError永远不会调用协议函数。有趣的是，另一个协议函数getNewPasswordDetails在之后很快被调用viewDidLoad，我不知道为什么。我相信在用户输入新密码等之前不应该调用它，并且应该响应.set但我可能是错的。
我的代码与示例代码和 SO 帖子完全相同，所以我不确定这里出了什么问题。
我的相关 AppDelegate 代码在这里：
extension AppDelegate: AWSCognitoIdentityInteractiveAuthenticationDelegate {
func startNewPasswordRequired() -> AWSCognitoIdentityNewPasswordRequired {
//assume we are presenting from login vc cuz where else would we be presenting that from
DispatchQueue.main.async {
let presentVC = UIApplication.shared.keyWindow?.visibleViewController
TransitionHelperFunctions.presentResetPasswordViewController(viewController: presentVC!)
print(1)
}
var vcToReturn: ResetPasswordViewController?
returnVC { (vc) in
vcToReturn = vc
print(2)
}
print(3)
return vcToReturn!
}
//put this into its own func so we can call it on main thread
func returnVC(completion: @escaping (ResetPasswordViewController) -> () ) {
DispatchQueue.main.sync {
let storyboard = UIStoryboard(name: "ResetPassword", bundle: nil)
let resetVC = storyboard.instantiateViewController(withIdentifier: "ResetPasswordViewController") as? ResetPasswordViewController
completion(resetVC!)
}
}
}
我相关的 ResetPasswordViewController 代码在这里：
class ResetPasswordViewController: UIViewController, UITextFieldDelegate {
@IBAction func resetButtonPressed(_ sender: Any) {
var userAttributes: [String:String] = [:]
userAttributes["given_name"] = firstNameField.text!
userAttributes["family_name"] = lastNameField.text!
let details = AWSCognitoIdentityNewPasswordRequiredDetails(proposedPassword: self.passwordTextField.text!, userAttributes: userAttributes)
self.newPasswordCompletion?.set(result: details)
}
}
extension ResetPasswordViewController: AWSCognitoIdentityNewPasswordRequired {
func getNewPasswordDetails(_ newPasswordRequiredInput: AWSCognitoIdentityNewPasswordRequiredInput, newPasswordRequiredCompletionSource: AWSTaskCompletionSource<AWSCognitoIdentityNewPasswordRequiredDetails>) {
self.newPasswordCompletion = newPasswordRequiredCompletionSource
}
func didCompleteNewPasswordStepWithError(_ error: Error?) {
DispatchQueue.main.async {
if let error = error as? NSError {
print("error")
print(error)
} else {
// Handle success, in my case simply dismiss the view controller
SCLAlertViewHelperFunctions.displaySuccessAlertView(timeoutValue: 5.0, title: "Success", subTitle: "You can now login with your new passowrd", colorStyle: Constants.UIntColors.emeraldColor, colorTextButton: Constants.UIntColors.whiteColor)
self.dismiss(animated: true, completion: nil)
}
}
}
}
