Question

我正在开发新的Firebase登录。数据库中有两个类别。＆＃34;烹调＆＃34;和＆＃34;客户＆＃34;。＆＃34;烹调＆＃34;有一个CookViewController和＆＃34;客户＆＃34;有一个customerViewController。登录后，我需要知道此电子邮件属于哪个类别，segue为CookViewController或CustomerViewController。下面是登录的代码，但我不知道如何分辨电子邮件属于哪个类别。谢谢！

 @IBAction func loginPressed(sender: AnyObject) {

    if let email = emailField.text where email != "", let password = passwordField.text where password != "" {

      FIRAuth.auth()?.signInWithEmail(email, password: password, completion: { (user, err) in

      if err != nil {

        print(err)

          } else {

       // Here I need to know whcih view Controller to Segue to:

            self.performSegueWithIdentifier(identifier: String, sender: self)

              }

 }

数据结构如下：

Answer 1

如何制作你的JSON： -

yourApp:{
 cooks:{
       email1:true,
       email3:true,
       email4:true,
       email7:true,
       email8:true},
 customers:{
       email2:true,
       email12:true,
       email13:true,
       email4:true,
       email8:true},
 users:{
       uid1:{
          email : blah@blah.com,
          isCook: true
            },

       uid2:{
          email : burp@blah.com,
          isCook: false
            }....
          } 
        }

因此，您可以签入cooks部分或客户部分或用户部分下的uid，然后与isCook节点相关联，如果他是 - ＆gt;转到cookViewController，否则转到customerViewController < / p>

最简单的方法是检查uid ： -

 FIRDatabase.database().reference().child("users/\(FIRAuth.auth()!.currentUser!.uid)/isCook").observeSingleEventOfType(.Value,withBlock:{(snap) in 
    if let isThisUserCook = snap.value as? Bool //or String{
           if isThisUserCook == true{

                //segue to cookVC
              }else{
                //segue to customerVC

                 }
            }
      })

Firebase如何验证要登录的电子邮件属于数据库中的哪个类别？
