Question

我已正确安装了所有pod。我的应用程序启动，然后当我到达必须访问Firebase的场景时，我注意到那里发生了崩溃。原因似乎是Firebase向我发出了2个不同的uid，而Auth中的那个并没有与数据库中的那个匹配。

当我的应用程序在AppDelegate中启动时，我有代码来获取当前的uid。

//This is in App Delegate
let myUserID = FIRAuth.auth()?.currentUser?.uid

print("App Delegate: UID is \(myUserID!)")
//An example print is 'App Delegate: UID is Abcdefg12345'

接下来会出现一个SignUp场景，在那个视图控制器中我有

FIRAuth.auth()?.createUserWithEmail(self.emailTextField.text!, password: self.passwordTextField.text!, completion: {

            //You can access the newly issued uid from user via user!uid
            (user, err) in

print("SignUp: UID is \(user!uid)\n")
//An example print is 'SignUp: UID is Vwxyz67890'

当我访问user！uid（来自用户）时，我得到了与AppDelegate中最初的uid完全不同的内容。

但是我在FIRAuth.auth（）？createSuserWithEmail中从用户获取的uid是Auth中的当前内容，但在FirebaseDatabase中无法识别。

奇怪的是，在AppDelegate中打印的uid是FirebaseDatabase中的当前内容，但在Auth中无法识别。如果在注册时更改了此uid，则它不应在数据库中可用

我还有一个注销场景，当我按下注销按钮时，我得到了注销uid，就像在FIRAuth.auth（）中创建的那个一样？。createUserWithEmail

为什么我有2个不同的uid？这似乎是我的崩溃问题。

Answer 1

你要求firebase获取app委托中的uid，而不检查用户是否已登录。它可能会为用户分配一个临时/匿名帐户，直到他们创建一个帐户。检查firebase控制台中的“Auth”设置，看看是否在此过程中创建了多个帐户。

从App Delegate中删除代码并将“let myUserID = FIRAuth.auth（）？。currentUser？.uid”移动到注册控制器中的“createUserWithEmail”函数
