Question

My app is receiving remote notifications (APNS) and is working for all the common scenarios:

• App is not running (didFinishLaunchingWithOptions:)
• App is running and active (didReceiveRemoteNotification:)
• App is running, the phone is locked and I unlock the device as soon as I get the notification (didReceiveRemoteNotification:)

However, not if I in the last case choose not to unlock the device immediately (with the slider) and I wait until the screen goes black again. The message/notification is still shown in the lock screen, but the slider can now only unlock the device and when I do, didReceiveRemoteNotification: doesn’t get called at all.

Answer 1

I’m afraid this is the intended behaviour. Quote the Local and Push Notification Programming Guide, part Scheduling, Registering, and Handling Notifications:

If the action button is tapped (…), the system launches the
application and the application calls its delegate’s
application:didFinishLaunchingWithOptions: method (…); it passes in
the notification payload (…). If the application icon is tapped (…),
the application calls the same method, but furnishes no information
about the notification.
