From the little information provided, I would proceed like the following :

Look at NSUserDefaults to see what was the previous iteration
Define a start time based on that previous iteration (if any)
Schedule a local notification using the Local Notifications provided in the iOS SDK.
Save that same date/time in the NSUserDefaults.
Once we reach that time, the notification will be sent (by iOS), and we can execute code to repeat this sequence.
