Enter iOS system wifi page, app luanch by 'NEHotspotHelper', then request is ofen timeout.

but when app enter foreground, request is success.

What is the reason for this? Is there a restriction on the background of the system? What is the rule of restriction?

Are you talking about a network request. If so, and that request is targeting the hotspot itself, make sure to bind the request to the hotspot interface via

-[NSMutableURLRequest bindToHotspotHelperCommand:]

There’s no obvious way to do that. Most folks use NSURLSession to talk to their hotspot authentication subsystem, and that’s certainly what I recommend. Why do you need to use BSD Sockets for this? Does your hotspot vend a non-HTTP interface? Or are you trying to reuse some existing BSD Sockets code?

If the hotspot is still blocking outgoing requests, WWAN should still be the default route, in which case a standard NSURLSession request will go via WWAN.
