如何检查用户是否具有有效的Auth Session Firebase iOS? [英] How to check if user has valid Auth Session Firebase iOS?

问题描述

在展示应用程序的Home View控制器之前，我想检查用户是否仍然具有有效的会话.我使用最新的Firebase API.我想如果我使用旧版软件，我就能知道这一点.

I wanna check if the user has still a valid session, before I present the Home View controller of my app. I use the latest Firebase API. I think if I use the legacy, I'll be able to know this.

这是我到目前为止所做的:

Here's what I did so far:

• 我在Firebase的Slack社区上发布了我的问题，没有人回答.我找到了这个，但这是针对Android的: https: //groups.google.com/forum/?hl=el#!topic/firebase-talk/4HdhDvVRqHc

我尝试阅读iOS版Firebase的文档，但似乎无法理解: https://firebase.google.com/docs/reference/ios/firebaseauth/interface_f_i_r_auth

I tried reading the docs of Firebase for iOS, but I can't seem to comprehend it: https://firebase.google.com/docs/reference/ios/firebaseauth/interface_f_i_r_auth

我尝试这样输入Xcode:

I tried typing in Xcode like this:

FIRApp().currentUser()
FIRUser().getCurrentUser()

但是我似乎找不到该getCurrentUser函数.

But I can't seem to find that getCurrentUser function.

推荐答案

if FIRAuth.auth().currentUser != nil {
   presentHome()
} else {
   //User Not logged in
}

对于更新的SDK

if Auth.auth().currentUser != nil {

}
