How to set iPhone alarm programmatically?

Question

This is a very straightforward question. I am developing an iphone app in which I am using a custom calendar. The user can set an alarm in this app. The events which the user adds to the calendar should not be visible in the default calendar application, which means I can't use default calendar application.

How do I set the alarm programmatically without replicating changes in default calendar?

Edit: I have used the iphonecal application by tinyfool for the calendar. If there is any way in that application to add timely alerts then please tell me. I couldn't find such functionality in that app.

Use local notifications to set up alarms for a certain time.
