The advice from Technote 2277 "Networking and Multitasking" still applies. <https://developer.apple.com/library/ios/#technotes/tn2277/_index.html> iOS has no special support for UDP networking in the background, so the only way to do this is to prevent your app from suspending (-beginBackgroundTaskWithName:xxx is one way to do that). There's good news and bad news on that front: * The good news is that, if you prevent your app from suspending, there's no difference between networking in the background vs the foreground. * The bad news is that the system puts strict limits on how long you can run in the background (to preserve device standby time).
