How it works in background ? #45

I use the framework to develop a IM app, but when the app enter background, it can not receive messages! What should I do?

@LiangyongFShen we don't make any assumptions about backgrounding or activity. If you're developing a chat application I strongly recommend you implement the background activity API's or use push notifications to wake up the app and resume the socket connection.

Alternatively you can use the VOIP flag on the stream but you'd need to fork PocketSocket and set that yourself. It's not something we really are targeting since a WebSocket isn't normally VOIP.

Thanks a lot ! Are that any blogs about setting VOIP flag on the stream ?

robertjpayne commented 8 years ago

@LiangyongFShen you normally have to be a Voice Over IP phone calling app to get that background activity entitlement through Apple App Review.

NSStreamNetworkServiceTypeVoIP is the flag you have to set on the stream, again you'll have to fork PocketSocket as you'll need to configure the stream.

Alternatively you can just use the PSWebSocketDriver and BYO networking.
