Apple推送通知折叠关键等效 [英] Apple Push Notification Collapse Key Equivalent

问题描述

使用Google推送通知时，我可以指定collapse_key值，这样设备就不会收到同一个collapse_key的多个通知。 APNS是否有类似的功能，或者是否有人知道模拟此功能的方法？

When using Google push notifications, I am allowed to specify a collapse_key value so a device will not receive multiple notifications of the same collapse_key. Does APNS have a similar feature or does anyone know a way to emulate this functionality?

推荐答案

iOS中没有这样的功能。但是，由于推送通知是由您控制的服务器发送的，因此您可以跟踪已发送到特定设备的通知，并决定是否发送新通知。换句话说，您将逻辑放在服务器代码中，而不是iOS应用程序代码中。

There is no such feature in iOS. However, since push notifications are sent by a server that is in your control, you can keep track of which notifications you've sent to a particular device, and decide whether or not to send new ones. In other words, you put the logic in your server code, not your iOS app code.
