iOS - 使用相同的消息和有效负载同时从同一服务器向多个应用程序发送推送通知的正确方法

Question

I have two separate applications in "development", lets call them App A and App B , that are supposed to receive the exact same message and payload from the same server as a push notification. Both have different application ids, certificate requests, provisioning profiles, development APN certificates, and produce different tokens.

If I send a push notification to either application individually each application will receive a notification. But if I try to send a push notification to each application concurrently, only the fist application will receive the notification. But I will receive no errors for the other application.

I have tried to delay the push notification by up to 10 seconds between sending the push notification to the last application without success. Is there some way that I need to handle the connections to the apple server to enable this type of push notifications?

Also note that there is another question that is having the exact same issue, but without any answers. Limitations on push notifications for multiple apps from the same server

I was able to get the notifications to be delivered to both of the applications successfully by closing the previous connection. This is not recommended by Apple, and they state that I should keep them open, as there is a potential to have a lot of notifications pushed per day to each application.

Keep your connections with APNs open across multiple notifications; don't repeatedly open and close connections. APNs treats rapid connection and disconnection as a denial-of-service attack

try to use two instance of your server , and keep your connection open while sending.

Connect each instance to a different port: 2195, 2196
