Scheduling iOS tasks

[Mark Schonewille]

Hi,

Push notifications would solve this problem, theoretically. Unfortunately, I'm not sure how LiveCode apps would handle push notifications, because LiveCode apps on iOS always shut down completely. They simply don't run in the background. I wonder if it were possible to start a LiveCode app when a push notification arrives. That might solve it.
