I have one application that connects to a network device (in LAN) over UDP and listen for new messages using GCDAsyncUdpSocket. It works fine in foreground but in background it is not able to respond. I want to show a local notification when I receive a message from UDP. Please suggest how we can achieve this by following Apple policies.

Thanks & Regards, Amit

All sockets are set to sleep when the app is in background.

The option you have is to do Fetching Small Amounts of Content Opportunistically

In case your app is a VoIP app, you can keep a TCP socket live and the OS will inform you when data is received. This way you can set a "wake up" message to be sent over TCP and then use UDP for the actual data transfer.
