We are trying to use local notifications in a new app we are working on. I need to know if we can use local notifications for alerts so that the user gets alerts when a scheduled one time event happens in the app. For example, if there is a holiday, the user needs to be notified about it. Can we use a custom calendar of custom events for this without merging this custom calendar into the iPhone's main calendar? About using push notifications instead of local notifications, is it true that Apple does not guarantee that alerts will be delivered at the expected time every time? This is our first app. Any assistance in helping us go with local/push notifications is greatly appreciated. Thank you.
