我的所有豆莢都已正確安裝。我的應用程序啓動，然後當我到達必須訪問Firebase的場景時，我注意到發生了崩潰。原因似乎是，Firebase向我發放了2個不同的uid，而Auth中的那個與數據庫中的不匹配。Firebase發出2個不同的uid's -Swift iOS
當我的應用程序在AppDelegate中啓動時，我得到了獲取當前uid的代碼。
//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'
下一個註冊的場景呈現，並在該視圖控制器我有
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'
當我訪問用戶！UID（來自用戶），我得到了最初是在AppDelegate中完全不同的UID 。
但是，我從用戶的FIRAuth.auth（）?. createUserWithEmail獲得的uid是Auth中的當前內容，但未在FirebaseDatabase中識別。
奇怪的是，在AppDelegate中打印的uid是FirebaseDatabase中的當前內容，但在Auth中無法識別。如果這個uid在註冊時改變了，那麼它不應該在數據庫中可用
我也有一個註銷場景，當我按下注銷按鈕時，我得到的註銷uid與FIRAuth.auth（）中創建的一樣。 ？.createUserWithEmail
任何想法，爲什麼我有2個不同的uid？這似乎是我的崩潰問題。

您應用程序的委託方法中設置myUserID沒有變化所以它在訪問數據庫時仍然使用該值。更改帳戶創建/登錄時的值 –
這就是你在做什麼： 1.一旦應用程序打開，你問火力基地爲一個uid 2。Firebase會創建並向您展示一個新的uid。我們稱之爲UID1 3.您將myUserID設置爲等於UID1 4.您創建一個新帳戶 5. Firebase爲該帳戶分配一個新的uid。我們稱之爲UID2 6.即使UID2現在已經登錄，您也可以使用UID1訪問數據庫，因爲您已經設置了該值 7.您註銷並詢問當前用戶的uid是什麼，這是我理解的UID2 –
你的邏輯，除了1件事情（不是你的邏輯，而是Firebase的）之外，它是完全合理的。你在AppDelegate中的說法我將myUserID設置爲UID1，我假設這是由常量設置的。但是我試圖完全刪除整個東西，這意味着我從來沒有設置它，所以我完全沒有使用該代碼。問題仍然存在。在這個項目中，myUserId與用戶！uid中創建的不一樣。我還有其他的vc在成功註冊後走到了線下，我使用FIRAuth.auth（）？currentUser？.uid來獲取uid，這是不匹配的。 –
