I dont think you are allowed to create your own calendar on an app, since historically they get rejected with 'Duplicates functionality of iPhone OS' message.
So, can you import the users calendar and display it?
And if so, can someone post a link to a tutorial or something please?
Thanks,
Sam
There is currently no API in the iPhone SDK that allows insertion of viewing of calendar information
Apple doesn't allow access to the calendar, similar to how there is no way to access the SMS database. I think their reasoning is that they don't want to give people the ability to write a basic functionality app to replace the phone's default app.
Maybe not though, because there is an address book API.
