apple-push-notifications

问题 I cannot seem the have my head around this. APNS as stated in the documentation has best-effort delivery, i.e. delivery is not guaranteed. However, if I am to use the push-notification model in my client/server application, I have to use them somehow.

If I disconnect the device from the charger (or Mac)

If the app is in the background, all the posts suggest to use application:didReceiveRemoteNotification: and check the application state. But as I experimented (and also as the name of

问题 I know this is covered in a lot of places, but I cannot figure this out. I use Urban Airship for push notifications. Everything seems to be fine except that when my app is in the background - didReceiveRemoteNotification is not getting called. It works when in the foreground - I am able to properly process messages. And I am able to get to messages from launch options if message is tapped from notifications center. But when in the background, a message it send - iOS displays the alert -
