推送通知徽章自动增量 [英] Push-Notification Badge auto increment

问题描述

我一直在为我的应用程序实现推送服务，我一直在考虑应用程序的徽章。我的应用程序是一个邮件应用程序（sorta），我想通过推送通知用户添加到收件箱中的新邮件，我想要徽章=收件箱中新邮件的数量。

I've been implementing the push service to my application, and I've been thinking about the application's badge. My app is a mail app (sorta) and I want to notify the user via push for new messages added to the inbox, I want the badge = number of new messages in the inbox.

我想做服务器端（提供商）检查新邮件并将号码作为徽章发送。

I thought of doing it server sided (provider) checking for new messages and sending the number as the badge.

问题是：
是有没有办法自动增加应用程序的徽章，而不必计算服务器侧的徽章值，然后将其作为推送有效负载的一部分发送到APSN？

The question is: Is there a way to auto-increment the application's badge, without having to calculate the badge value server sided and afterwards sending it as a part of the push payload to the APSN?

也许有一种方法可以在JSON徽章字段中发送一些变量，如++或类似的东西。
任何黑客攻击？或者我是否需要使用服务器端的计数系统??

Maybe there's a way to send in JSON badge field some variable like "++" or something like that. Any hack for that? Or do I need to go with the counting system server-sided??

推荐答案

不，你必须跟踪这个服务器端。如果您没有包含徽章的任何值，它将被完全删除。

Nope, you'll have to track this on the server side. If you don't include any value for badge, it will get removed completely.

当然，这只是在用户收到通知且应用不是正在运行/他们选择不启动它。如果用户启动应用程序或已经运行该应用程序，您可以执行任何有关增量的操作。

Of course though this is only if the user receives the notification and the app isn't running/they choose not to launch it. If the user launches the app or already had it running you can do whatever you want in regards to incrementing.

更新2014年3月：查看评论可能的更新。几年后我没有做过推动，所以我自己也无法验证。

UPDATE March 2014: See comments for a possible update. I haven't done pushes in several years so haven't been able to verify this myself.
