iOS更新推送内容扩展 [英] iOS update push in content extension

问题描述

iMessage在屏幕上显示丰富推送时会进行更新.您可以看到什么是用户现在输入RIGHT，消息将被添加到您的对话中.

iMessage updates the rich push when it's on the screen. You can see what is user is typing RIGHT NOW, and message will be added to your conversation.

所以问题是:当我已经在查看已打开的丰富推送时，如何捕获新的推送通知? UNNotificationContentExtension 中是否有任何事件可以捕获新事件并更新视图?我唯一知道的是:

So the question is: how i can catch new push notification, when i'm already looking at opened rich push? Is there any event in UNNotificationContentExtension to catch the new one and update view? The only one i know is:

- (void)didReceiveNotification:(UNNotification *)notification

，但是只有在您第一次打开推送时才会触发

but it is triggered only when you open the push first time

在UNNotificationContentExtension协议中发现了这一点:

Found that in UNNotificationContentExtension protocol:

// This will be called to send the notification to be displayed by
// the extension. If the extension is being displayed and more related
// notifications arrive (eg. more messages for the same conversation)
// the same method will be called for each new notification.
- (void)didReceiveNotification:(UNNotification *)notification;

所以它应该可以工作，但是我还是无法捕捉到此事件.也许我需要以某种方式使新通知与当前显示相关"?

So it should work but i can't catch this event anyway. Maybe i need somehow to make new notification "related" to currently displayed?

推荐答案

弄清楚问题出在哪里.

Apple文档:

显示通知时，系统以可视方式进行分组 具有相同线程标识符的通知.对于远程 通知，此属性的值设置为 aps字典中的thread-id键.

When displaying notifications, the system visually groups notifications with the same thread identifier together. For remote notifications, the value of this property is set to the value of the thread-id key in the aps dictionary.

在将密钥"thread-id"添加到aps字典后，此功能现在可以正确接收事件了

After adding key "thread-id" to aps dictionary, this func now receiving events correctly

- (void)didReceiveNotification:(UNNotification *)notification;
