I've followed this thread to implement VoIP push notifications, however I don't seem to be receiving any sort of notifications.
I've tried both with ssl://gateway.push.apple.com:2195
and ssl://gateway.sandbox.push.apple.com:2195
and I get the message 'Message successfully delivered'
in both cases, however pushRegistry:didReceiveIncomingPushWithPayload:forType:
is never executed.
I've added a simple background color change as well as a UIAlertController to be shown, yet still nothing.
Any idea how I could debug the cause of this problem?
