如何触发远程推送通知，当使用批处理的iOS开发时，用户对Firebase数据库节点值进行了更改?

I am using a Firebase database for my iOS Swift app. After going through a volume of material online, I decided to try Batch+Firebase to provide remote push notifications to a logged-in, authenticated user within an app, whenever node values in his/her database changes. I save the logged-user UID like so:

我正在为我的iOS Swift应用使用一个Firebase数据库。在网上查阅了大量资料后，我决定尝试Batch+Firebase，在一个应用中为登录的、经过验证的用户提供远程推送通知，只要他/她的数据库中的节点值发生变化。我将登录用户UID保存为:

 override func viewDidLoad(){
      super.viewDidLoad()
      //...
     editor = BatchUser.editor
     editor.setIdentifier("uid" as String!)
     editor.save()
 }

Of course, I have done the necessary background work for enabling push notifications for my app. Also, have installed pods of both Firebase and Batch, and I get user to activate notification settings.

当然，我已经做了必要的后台工作，为我的app启用推送通知。另外，我已经安装了Firebase和Batch的pods，我让用户激活通知设置。

I am not certain how to write the changed database values into a push notification and deliver to a user. I searched a lot for relevant tutorials online, but to no avail.

我不确定如何将修改后的数据库值写入push通知并交付给用户。我在网上搜索了很多相关的教程，但都没用。

Any direction on how to implement the Batch APIs in Swift for Firebase will be greatly appreciated.

对于如何在Swift中为Firebase实现批处理api，我们将非常感激。

If you want to send push notifications directly from the app (users to users), you'll have to use Batch Transactional API with custom_ids (Firebase UID) in the recipients list instead of push tokens.

如果您想要直接从应用程序(用户到用户)发送推送通知，您必须在收件人列表中使用带有custom_id (Firebase UID)的批处理API，而不是推送令牌。

You'll have to learn how to call a REST API from Swift code.
