问题
Here's the problem, when the app is attached to xcode, didReceiveRemoteNotification:fetchCompletionHandler is called.
But when i detach it, it's not called even when the notification is received.
I attached app again (debug->attach to process) & send the notification, didReceiveRemoteNotification:fetchCompletionHandler called again.
Someone could explain why didReceiveRemoteNotification:fetchCompletionHandler was not called when i detach it from xcode ?
The app was not force closed. I just open it & put it to background.
Tested in iPhone 5 iOS 8.0.2
APNS Sandbox.
Thank you.
