Firebase发布了两个不同的uid的-Swift iOS [英] Firebase issuing out 2 different uid's -Swift iOS
问题描述
当我的App在AppDelegate I有代码获得当前的uid。
$ $ p $ //这是在App Delegate
let myUserID = FIRAuth.auth（ ）？currentUser？.uid
print（App Delegate：UID is \（myUserID！））
//示例打印为'App Delegate：UID is Abcdefg12345'
接下来会显示注册场景，并在该视图控制器中显示
FIRAuth.auth（）？。createUserWithEmail（self.emailTextField.text !,密码：self.passwordTextField.text !,完成：{
//你可以通过用户通过用户访问新发布的用户id
（user，err）
$ b print（SignUp：UID is \（user！uid）\ n）
//示例打印是'SignUp：UID是Vwxyz67890'
我访问用户！使用（从使用r）我从AppDelegate中得到了完全不同的uid。
然而，我从FIRAuth.auth（）中获得的用户名是什么？createUserWithEmail是什么目前在Auth中，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。如果这个uid在注册时发生了变化，那么它不应该在数据库中可用。
我也有一个注销场景，当我按下注销按钮时，我得到注销uid如同在FIRAuth.auth（）中创建的一样？createUserWithEmail
任何想法为什么我有2个不同的uid？这似乎是我的崩溃问题。

让字典= [String：AnyObject]（）

应用程序委托，而不检查用户是否登录。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，看看是否有多个帐户正在创建。
从App Delegate中删除代码并将let myUserID = FIRAuth.auth（）？。currentUser？.uid添加到注册控制器的createUserWithEmail函数中
I have all my pods correctly installed. My app launches and then when I get to scenes that have to access Firebase I've noticed there's a crash. The reason seems to be that Firebase is issuing me 2 different uid's and the one in Auth doesn't match the one in the Database.
When my app launches in AppDelegate I have code to get the current 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'
Next a SignUp scene is presented and in that view controller I have
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'
When I access user!uid (from user) I get a totally different uid from what is originally in the AppDelegate.
However the uid that I get from user in FIRAuth.auth()?.createUserWithEmail is what's current in Auth but is not recognized in FirebaseDatabase.
The odd thing is the uid that is printed in AppDelegate is what's current in the FirebaseDatabase but is not recognized in Auth. If this uid is changed upon signing up then it should not be available in the Database
I also have a logout scene and when I press the logout button I get the logout uid as the same one created in FIRAuth.auth()?.createUserWithEmail
Any ideas why I have 2 different uid's? This seems to be my crash issues.

You're asking firebase for a uid in the app delegate without checking if a user is logged in. It may be assigning a temporary/anonymous account to the user until they create an account. Check the "Auth" settings in the firebase console and see if multiple accounts are being created in the process.
Remove the code from the App Delegate and move "let myUserID = FIRAuth.auth()?.currentUser?.uid" into the 'createUserWithEmail' function in the signup controller
