主题不会保存在Firebase中 [英] Topic Won't Save in Firebase

问题描述

我尝试让用户订阅某个主题并将其保存在Firebase中。我已经按照firebase.google.com的指南进行了操作，并在用户点击按钮时添加了以下代码：

  [ [FIRMessaging messaging] subscribeToTopic：@/ topics / sampletopic]; 
  

虽然当我测试点击这个按钮时没有任何反应。我已经添加了必要的pod文件。我错过了什么？

编辑：这些甚至在Firebase中显示？在哪里可以看到我保存的主题？

解决方案

主题自动创建，只要有订户。但是，对于FCM，在控制台中大约需要24小时才能使用，也可以在以下帖子中看到：

您可以在 Firebase控制台中发送新消息时查看>，然后在目标部分选择 主题 。

I'm trying to let a user subscribe to a Topic and save it in Firebase. I've followed the guides from firebase.google.com and have added the following code when a user taps a button:

[[FIRMessaging messaging] subscribeToTopic:@"/topics/sampletopic"];

Nothing happens though when I test clicking this button. I've added what is necessary to the podfile. What am I missing?

edit: where does this even show up in Firebase? Where can I see my saved topics?

解决方案

A topic is created automatically so long that there is a subscriber. However, for FCM, it takes about 24 hours for it to be available in the console, as also mentioned in the following posts:

You can view it when you are going to Send a New Message in the Firebase Console, then in the Target section, choose Topic.
