iOS Running in background/trigger by alarm

[norbjarte]

Case: Need a way to trigger a notification every X minutes (like 15, 20) to my program, which plays a notification.

Pros: Experienced programmer
Cons: Learning iPhone and OSX programming.

Solution A: Run program in background? How?
Solution B: Create a crontab simular event to trigger a event? How?

PS: The interval (X minutes) should be able to be set from the program.

Anyone could help point me in the right direction to look for a solution, if its possible?

Not possible at the moment. Apple will supply a push notification service later this year (hopefully, the timetable has already slipped) which would allow you to prompt the user to run the program. But you can't automatically trigger it ever X minutes, even with the push notification service.

Using the SDK API's, there is no way to run any program or process in the background. And you can't access cron because it's outside your application's sandbox.

And you can't access cron because it's outside your application's sandbox.

Less that and more the fact that you can't fork processes because of the sandbox's limitations.
