Staying connected (or reconnecting) for background processes

[casparwylie]

My system involves accessing network data when the app is in background. After a while trying to work out the problem, it turns out the socket connection drops once a user enters background. I've been struggling to find a successful work around. Is there anything in Starscream that would help?

Same here. I'm updating an app that used to work without problems in background but now it stop sending "keep alive" messages when the app goes background. Any workaround for this?

BTW, I'm talking about having the app in background (just closing the app, not killing the process). I can't have background modes in the app, just regular background operation

The standard app lifecycle will cause the socket connection drop when entering the background. Nothing "official" can be done to prevent that. In the past people use to abuse the VOIP background mode to allow this (see #309 for more details), but Apple frowned on this as it isn't the intend use case. As that issue notes, this restriction is now strictly enforced in iOS 10. The recommend course of action is to have a server that does all the processing and wakes the app up with push notifications with the new data you need.
