您好我需要帮助，我已经阅读了其他一些解决方案，他们似乎没有帮助，因为他们都与手势或按钮有关。任何帮助表示赞赏。
这是我的代码：
import UIKit
import FirebaseAuth
class SignInVC: UIViewController {
@IBOutlet weak var signInSelector: UISegmentedControl! //Login/Sign Up Selector
@IBOutlet weak var emailTextField: UITextField! //Text Field for Email
@IBOutlet weak var passwordTextField: UITextField! //Text Field for Password (Protected)
@IBOutlet weak var loginButton: UIButton! //Login Button
@IBOutlet weak var loginLabel: UILabel! //Login Label
var isLogin:Bool = true //Boolean for is Login Screen
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func signInSelectorChanged(_ sender: UISegmentedControl) {
isLogin = !isLogin //Flip the boolean
if isLogin {
loginLabel.text = "Login"
loginButton.setTitle("Login", for: .normal)
} //If Statement
else {
loginLabel.text = "Sign Up"
loginButton.setTitle("Sign Up", for: .normal)
} //Else Statement
}
@IBAction func loginButtonTapped(_ sender: UIButton) {
if let email = emailTextField.text, let pass = passwordTextField.text {
if isLogin {
//Login through Firebase
Auth.auth().signIn(withEmail: email, password: pass, completion: { (user, error) in
if let u = user {
//User is found go to homescreen
self.performSegue(withIdentifier: "ContactsSegue", sender: self)
}
else {
//Register the user with Firebase
}
})
} //If Statement
else {
//Register the user with Firebase
Auth.auth().createUser(withEmail: email, password: pass, completion: { (user, error) in
if let u = user {
//User is found go to homescreen
self.performSegue(withIdentifier: "ContactsSegue", sender: self)
} //If Statement
else {
//Register the user with Firebase
} //Else Statement
})
} //Else
} //Overarching If Statement
} //Sign Up Button
} //Class
这是我的控制台：

您在login: viewcontroller中缺少SignInVC方法。
尝试在SignInVC viewcontroller中添加此功能。
@IBAction func login(_ sender: UIButton) {
self.loginButtonTapped(sender)
}
