iOS silent push notification cancelled

问题

In my application, I use silent push notification in order to communicate regularly, but I am in trouble because the silent push notification I received while not launching the application is not processed. OS version is iOS12. I am using FCM to send push notifications. Is there anyone with the same problem?

Below is the console log when you receive a notification silent push notification.

回答1:

I had a similar issue. I eventually discovered that disabling background refresh also disables the delivery of silent notifications to suspended apps.

In this case, if you enable background refresh, does iOS launch your app and deliver the notification to your app delegate?

回答2:

In my case the problem was the lake of other properties in the payload. I was using this payload at the beggining:

{"aps":{"content-available":1}}

but adding the Sound property fixed the problem:

{"aps":{"content-available":1, "sound":""}}
