Detect if application: didReceiveRemoteNotification: fetchCompletionHandler: was called by tapping on a notification in Notification Center

Question

application: didReceiveRemoteNotification: fetchCompletionHandler:

is different from

application: didReceiveRemoteNotification:
         


        

Answer 1

Application State is not reliable because if you have control center or Apple's notification center open over your app, application: didReceiveRemoteNotification: fetchCompletionHandler: will get called and the application state will be Inactive.

I'm having the same issue trying to respond to a click on the notification while the app is in the background and there doesn't seem to be a reliable way to solely identify this.
