I (Basically) need to create a background timer on iOS 4 that will allow me to execute some code when a specific amount of time has passed. I have read that you can accomplish this using some [NSThread detachNewThreadSelector:
toTarget:
withObject:]; but how does that work in practice? How can I ensure that the thread remains in the background also. Local notifications will NOT work for me, as I need to execute code, not notify the user.

Help would be appreciated!
