如何使用iOS / Swift中的startPasswordAuthentication委托切换到登录屏幕，以便基于Cognito用户池登录？

Question

我已经使用aws-ios-sdk-2.4.5将CognitoYourUserPoolsSample的Obj-C代码翻译成Swift。 我已经设置了一个用户池，一个应用程序，并在项目中包含了正确的ID。 但是，当我运行应用程序时，startPasswordAuthentication委托方法永远不会被调用，我无法弄清楚原因。 我在下面的AppDelegate.application方法中包含了代码。 如果有人能给我一些关于如何修复/调试它的指示，那将非常有帮助。

class AppDelegate: UIResponder, UIApplicationDelegate, AWSCognitoIdentityInteractiveAuthenticationDelegate {

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    AWSLogger.defaultLogger().logLevel = AWSLogLevel.Verbose
    let sc = AWSServiceConfiguration(region: .USEast1, credentialsProvider: nil)
    let upc = AWSCognitoIdentityUserPoolConfiguration(clientId: clientId, clientSecret: clientSecret, poolId: userPoolId)
    AWSCognitoIdentityUserPool.registerCognitoIdentityUserPoolWithConfiguration(sc, userPoolConfiguration: upc, forKey: "UserPool")
    let pool = AWSCognitoIdentityUserPool(forKey: "UserPool")
    self.storyboard = UIStoryboard(name: "Main", bundle: nil)
    pool.delegate = self
    return true
}

func startPasswordAuthentication() -> AWSCognitoIdentityPasswordAuthentication {
    print("show login ui")
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let loginViewController = mainStoryboard.instantiateViewControllerWithIdentifier("LoginViewController") as? LoginViewController
    dispatch_async(dispatch_get_main_queue(), {
        self.window?.rootViewController = loginViewController
    })
    return loginViewController!
}
}

我能够在本地运行Obj-C示例项目，并且正在调用startPasswordAuthentication delete方法！

我不知道我是不对，但我认为你忘了用身份池迁移你的游泳池。

let sc = AWSServiceConfiguration(region: .USEast1,credentialsProvider: nil)

AWSServiceManager.defaultServiceManager().defaultServiceConfiguration = sc

let upc = AWSCognitoIdentityUserPoolConfiguration(clientId: "CLIENT_ID", clientSecret: "CLIENT_SECRET", poolId:"USER_POOL_ID")

AWSCognitoIdentityUserPool.registerCognitoIdentityUserPoolWithConfiguration(sc, userPoolConfiguration: upc, forKey: "UserPool")

let pool = AWSCognitoIdentityUserPool(forKey:"UserPool")

***credentialsProvider = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "COGNITO_IDENTITY_POOL_ID, identityProviderManager:pool)***
