ios - What happens if the user closes an app that is already in the background? -


during background task execution happen if user kills app (which in background mode)?

picture this:

the app starts task x (with 10 min background support , expiration handler has called). then, app goes background , user kills app.

i'm confused on happen task x after app killed. still have background time execute? expiration handler ever gets called?

if app "already in background", user has already "closed app"! can question mean? you've gone background, , if called beginbackgroundtaskwithexpirationhandler: did so, things proceed normally.

do mean user forcibly kills app in background, summoning "recent apps" interface , going jiggy mode , deleting app "recent apps" interface? app summarily killed; no notification , whatever doing interrupted.

moreover, thing expiration handler block supposed call endbackgroundtask:. if summarily killed, fact unable make call unimportant!
