Question

这对我来说是一个奇怪的问题。

基本上，我正在构建一个应用程序，在登录并验证用户身份后，它将打开一个页面，从Firebase数据库加载数据并保存到领域。

一切正常，直到我尝试在没有登录的情况下验证用户身份（检查他们是否已经登录以便自动启动主页视图控制器）。

这是我的身份验证码

import Foundation
import FirebaseAuth

class AuthUser {

  func userCheck(completion:(message:String)->()){

    var message = ""

    let user = FIRAuth.auth()?.currentUser

    if (user != nil) {

        print("User is already logged in")

        message = "LoggedIn"

    } else {

        print("User is not logged in")
        message = "notLoggedIn"

    }

    completion(message: message)

  }
}

这是我的导入数据代码

import Foundation
import FirebaseDatabase
import FirebaseAuth
import RealmSwift

class MenuDataRealm {

  func importData(completion: (message:String)->()){

    print("Initiating Menu Data Import...")

    // Realm
    let realm = try! Realm()

    print("Importing...")

    let ref = FIRDatabase.database().reference()

    ref.child("Category").observeSingleEventOfType(.Value, withBlock: { (snapshot) in

        print("Start Menu Data Retrieval")
....

问题是，在记录时，日志在“导入...”之后停止打印并停在那里。如果我正常登录（而不是自动验证用户），它将完美地运行整个功能，并且不会停留在“导入...”

这是正常登录的日志

还有一件值得一提的事情是，它有时可以正常工作，并且在我自动进行身份验证时运行整个函数。

但是，这只会在我删除AuthUser.userCheck函数，重新启动应用程序，通过手动输入方法登录并重新添加该功能后立即发生。

似乎auth函数尽管显示用户已登录，但并不总是如此，因此数据库查询不起作用。

但是，我通过将数据库读写规则更改为true来测试它，允许访问而不进行身份验证，但它仍然停留在“导入...”，尽管这样做。

我希望这不会太混乱，如果您需要任何其他信息来了解我的问题，请告诉我。

尝试导入Firebase，因为它位于顶部。我相信您不再需要导入FireAuth以及所有这些。 Firebase应该保持原样。

import Firebase

^这就是我需要做的所有事情，以便进行身份验证，与数据库交谈，等等。

我不完全理解您的问题，但如果您在初始化用户时遇到问题并通过查询观察他的信息。这是我为了获取信息和更新当前用户的文本标签而做的。：

var user: FIRUser!
func authenticateUser() {
    self.user = FIRAuth.auth()?.currentUser
    FIRDatabase.database().reference().users.child(user!.uid).child("userInfo").observeEventType(.Value) { (snapshot: FIRDataSnapshot) in

        self.fullNameValue = snapshot.value!["fullName"] as! String

        }
}

我希望我能提供帮助。
