ios - 发布到主题时 Apple 推送通知的 Amazon SNS 更新角标(Badge)计数器

Question

我知道在发布到单个设备时可以设置角标(Badge)计数器，但是在发布到订阅了特定主题 ARN 的所有 设备时是否可以设置独立于设备的计数器？

当前的用例是，可能有多达一百万的用户订阅了某个主题，并且必须将推送通知一个一个地发布到每个设备 ARN(与主题 ARN 相对)，从服务器端的角度来看，这似乎效率很低.

使用的框架

后端:Python 带有 BOTO AWS SDK 和 SQLAlchemy 的 Flask 框架

前端:iOS

简答

不，你不能。

Apple 不允许您发送“+1”作为角标(Badge)编号，因此向订阅特定主题的所有用户发送相同的角标(Badge)编号应该对您没有帮助。

AWS SNS 允许您针对同一主题为每个平台制作自定义负载，因此这应该不是问题:

To send a message to an app installed on devices for multiple platforms, such as GCM and APNS, you must first subscribe the mobile endpoints to a topic in Amazon SNS and then publish the message to the topic. The following example shows a message to send to subscribed mobile endpoints on APNS, GCM, and ADM

http://docs.aws.amazon.com/sns/latest/dg/mobile-push-send-custommessage.html#mobile-push-send-multiplatform

{ 
"default": "This is the default message which must be present when publishing a message to a topic. The default message will only be used if a message is not present for 
one of the notification platforms.",     
"APNS": "{\"aps\":{\"alert\": \"Check out these awesome deals!\",\"url\":\"www.amazon.com\"} }",
"GCM":"{\"data\":{\"message\":\"Check out these awesome deals!\",\"url\":\"www.amazon.com\"}}",
"ADM": "{ \"data\": { \"message\": \"Check out these awesome deals!\",\"url\":\"www.amazon.com\" }}" 
}
