You're using local notifications, which is a good start, but you should know that local notifications are only displayed if your app is in the background. If your app is running in the foreground when the time comes you will need to display the notification yourself (UIView / UIAlertView).

You can schedule the local notification whenever you want, it really depends what editing you allow the user to do and, therefore, how much you might need to cancel the local notification and schedule a new version.

Few other things:

  • Consider using 'NSDate -dateByAddingTimeInterval' (it's just less code for your use case)
  • You're adding a minute to your date, so the alarm will be after the event (and say the appointment is in 30 minutes time ?)
  • Use NSLocalizedString for any string that will be displayed to the user
  • In the future, store less data in the appDelegate, that ins't what that class is for :)
