Question

自从使用正确的密码更新到Swift 3.0后，我收到了错误的消息。在Firebase上授权用户有没有人遇到此问题？

@IBAction func LoginToAccount(_ sender: AnyObject) {

    if let email = emailLogin.text, let password = passwordLogin.text {

    FIRAuth.auth()?.signIn(withEmail: email, password: password, completion: {
        (user, error) in


        if error != nil{
            print("Incorrect")
            let alert = UIAlertController(title: "Error", message: "Incorrect Email or Password.", preferredStyle: UIAlertControllerStyle.alert)
            let action = UIAlertAction(title: "Ok", style: .default, handler: nil)
            alert.addAction(action)
            self.present(alert, animated: true, completion: nil)
        }else{
            if error == nil   {
            self.performSegue(withIdentifier: "AdminSegue", sender: self)

               }
            }
        })
     }
   }
}

Answer 1

如果您可以创建电子邮件并且登录有问题，那么就像我的情况一样。只需从yourproject.xcodeproject检查您的钥匙串辅助功能 - ＆gt;能力 - ＆gt;钥匙串分享 - ＆gt;如果它关闭了。

Answer 2

经过一些研究，这显然是Simulator 10.0不允许Firebase将值写入钥匙串的问题。他们正在研究的东西显然不会影响实际设备上的应用程序。

Answer 3

您必须确保最初创建用户，因为您必须先创建用户，然后使用创建的用户登录。

@IBAction func LoginToAccount(_ sender: AnyObject) {

    if let email = emailLogin.text, let password = passwordLogin.text {

       FIRAuth.auth()!.createUser(withEmail: email, password: password) { user, error in
       if error == nil {
       FIRAuth.auth()!.signIn(withEmail: email, password: password, , completion: { (user, error) in


          if error != nil{
             print("Incorrect")
             let alert = UIAlertController(title: "Error", message: "Incorrect Email or Password.", preferredStyle: UIAlertControllerStyle.alert)
             let action = UIAlertAction(title: "Ok", style: .default, handler: nil)
             alert.addAction(action)
             self.present(alert, animated: true, completion: nil)
           } else {
             if error == nil   {
             self.performSegue(withIdentifier: "AdminSegue", sender: self)
           }
         }
       })
      }
   }    
}

使用Swift 3.0的Firebase授权不起作用
