swift - Swift 3 的 SignInWithCredentials 给我带来了 Firebase for Facebook 登录的麻烦

Question

我的 Facebook 登录正常，Firebase 网站上的最后 2 条说明是:

let credential = FIRFacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current().tokenString)

和

FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in
            // ...
}

第一个工作正常，但第二个，Swift 说“signInWithCredential”现在已更改为“signIn”，当我将其更改为那个时，它告诉我:

Argument labels '(:,:)' do not match any available overloads

不太确定要做什么:

FIRAuth.auth()?.signIn(credential) { (user, error) in
    // ...
}

Answer 1

想通了。它是:

FIRAuth.auth()?.signIn(with:credential) { (user, error) in
    // ...
}
