Question

我是新工作的firebase，我正在登录并使用firebase为应用注册窗口。

现在，只要我从控制台创建帐户，登录就可以正常工作 This is what the login code looks like

但是如果你想要创建一个新帐户，你可以点击那个按钮，然后它会带你到一个新的viewcontroller窗口，在那里我添加了一些东西来填充以创建一个新帐户并且我使用了

FIRAuth.auth()?.createUserWithEmail(<email: String>, password: <String>, completion: <FIRAuthResultCallback?(FIRUser?, NSError?) -> Void#>)

这里是代码看起来如何的图片 picture of the code and the imageview

当我尝试注册一个新用户时，我得到了无效的消息，我真的不知道它为什么不创建一个新用户

奖金问题当我让它工作时如何让它从那个窗口移动到另一个窗口？

这应该有效：

var ref: FIRDatabaseReference!


override func viewDidLoad() {
    super.viewDidLoad()

    ref = FIRDatabase.database().reference()
    // Do any additional setup after loading the view.
}


@IBAction func signup(sender: AnyObject) {
    if let em = email.text, pass = password.text{
        FIRAuth.auth()?.createUserWithEmail(email.text!, password: password.text!) {(user, error) in
            if let error = error {
                print(error.localizedDescription)
            }
            else {
                print("User signed in!")

                self.ref.child("data/users").updateChildValues(["\(FIRAuth.auth()!.currentUser!.uid)":["Username":self.username.text!]])

                self.performSegueWithIdentifier("home", sender: self)
                //At this point, the user will be taken to the next screen
            }
        } }
    else{
        print("You left email/password empty")
    }
}

确保您已安装Firebase，FirebaseAuth和FirebaseDatabase（如果您正在使用cocoapods，则您的pod应如下所示）

pod 'Firebase'
pod 'Firebase/Auth'
pod 'Firebase/Database'

尝试我的代码小巧易懂

import UIKit
import Firebase

class RegisterViewController: UIViewController {

@IBOutlet weak var emailTextfield: UITextField!
@IBOutlet weak var passwordTextfield: UITextField!


@IBAction func registerPressed(_ sender: UIButton) {

    if let email = emailTextfield.text, let password = passwordTextfield.text {
        Auth.auth().createUser(withEmail: email, password: password) { authResult, error in
            if let e = error {
                print(e.localizedDescription)
            } else {
                //Navigate to the ChatViewController
                self.performSegue(withIdentifier: "RegisterToChat", sender: self)
            }
        }
    }
}

}
