我正在使用 AWS iOS SDK v2 和 Facebook iOS SDK v2.2。我正在尝试使用 Facebook 令牌作为 AWS 凭证提供商的“登录名”。问题是，我不知道如何在 iOS Swift 中设置登录。下面是我的代码：

if (FBSession.activeSession().state == FBSessionState.CreatedTokenLoaded) {
    // If there's one, just open the session silently, without showing the user the login UI
    FBSession.openActiveSessionWithReadPermissions(["public_profile", "email", "user_friends"], allowLoginUI: false, completionHandler: { (fbSession, fbSessionState, error) -> Void in
    // Handler for session state changes
    // This method will be called EACH time the session state changes,
    // also for intermediate states and NOT just when the session open
    if (error == nil) && (fbSessionState == FBSessionState.Open) {
        var token: String = fbSession.accessTokenData.accessToken
        var logins: NSDictionary = NSDictionary(dictionary: ["AWSCognitoLoginProviderKey.Facebook" : token])
        self.credentialsProvider.logins = logins
        self.credentialsProvider.refresh()...}

但我不认为登录字典是正确的......我试过了

[AWSCognitoLoginProviderKey.Facebook：令牌]

但是 XCode 说它不符合 NSCopying。

这里非常欢迎提示！谢谢！！！

我从 AWS 论坛得到了答案：

var logins: NSDictionary = NSDictionary(dictionary: ["graph.facebook.com" : token])
