Question

こんにちは私はこれに助けが必要です。他の解決策を読んでいて、ジェスチャーやボタンとは関係ありません。どんな助けもありがとうございます。ここで

私のコードです：ここでは

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

何とか何とかスペースを埋めます。

Answer 1

SignInVCビューコントローラにlogin:メソッドがありません。

SignInVCビューコントローラでこの機能を追加してみてください。誤差に基づいても

@IBAction func login(_ sender: UIButton) { 
    self.loginButtonTapped(sender) 
}
