我已经在这个问题上挣扎了几天,我是一个菜鸟,我无法找到解决办法。我正在尝试使用XCode 8.3.3创建一个用户注册和登录页面,并使用Firebase作为数据库。
我的代码如下:

import UIKit
import Firebase
import FirebaseAuth

class SignUpViewController: UIViewController {

    //Outlets
    @IBOutlet weak var emailTextField: UITextField!
    @IBOutlet weak var passwordTextField: UITextField!

    //Sign Up Action for email
    @IBAction func createAccountAction(_ sender: AnyObject) {

        if emailTextField.text == "" {
            let alertController = UIAlertController(title: "Error", message: "Please enter your email and password", preferredStyle: .alert)

            let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
            alertController.addAction(defaultAction)

            present(alertController, animated: true, completion: nil)
        } else {
            FIRAuth.auth().createUser(withEmail: emailTextField.text!, password: passwordTextField.text!) { (user, error) in

            if error == nil {
                print("You have successfully signed up")
                //Goes to the Setup page which lets the user take a photo for their profile picture and also chose a username

                let vc = self.storyboard?.instantiateViewController(withIdentifier: "Home")
                self.present(vc!, animated: true, completion: nil)

            } else {
                let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)

                let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
                alertController.addAction(defaultAction)

                self.present(alertController, animated: true, completion: nil)
            }
        }
    }
}

有问题的部分是FIRAuth.auth。错误显示“FIRAuth已重命名为Auth”,如果我应用了这样的修复,尽管构建成功,但我只能看到一个白色屏幕。如果删除代码,则可以看到先前创建的正常登录屏幕。
另一件事是,当我输入importFirebaseAuth时,建议的单词列表中出现了一条红线,划掉了FirebaseAuth,我仍然继续。
请帮忙。我不知道为什么会这样。有没有丢失的pod文件?非常感谢。

最佳答案

FIRAuth在最后一个Auth版本中变成了Firebaselink to Docs

import Firebase

然后,在application:didFinishLaunchingWithOptions:方法中,初始化FirebaseApp对象:
// Use Firebase library to configure APIs
FirebaseApp.configure()

现在您可以在文件中使用(也可以import Firebase
Auth.auth().createUser(withEmail: email, password: password) { (user, error) in
    // ...
}

希望有帮助

关于ios - 无法使用Firebase身份验证:FIRAuth.auth不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/44559027/
