swift - Microsoft 通过 Firebase 登录

Question

我对应用程序开发非常陌生，所以请原谅我。我研究了太久，似乎无法理解如何使用 Firebase 为 Microsoft 登录编写登录按钮。这是到目前为止我的代码:

import UIKit
import FirebaseAuth

class LoginViewController: UIViewController {

    var ref : DatabaseAuth!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

    }


    @IBAction func logIntapped(_ sender: Any) {

        let provider = OAuthProvider(providerID: "microsoft.com")
        provider.getCredentialWith(nil) { (credential, error) in
            if error != nil {
                // Handle error.
                print("Failed to retreive credential.")
                return
            }
            if credential != nil {
                Auth.auth().signIn(with:completion:)(<#AuthCredential#>) { authResult, error in
                    if error != nil {
                        // Handle error.
                    }
                }
            } else {
                print("Credential is nil.")
            }
        }
    }
}

您需要将从 Microsoft 获取的凭据传递到对 Firebase 身份验证的调用中。所以类似:

Auth.auth().signIn(with: credential) { authResult, error in
  ...
