Iphone: Event Creation using Kal

Hi i am in the process of making a tab bar application where one of the tabs is a calend开发者_如何学Goar..

To make the calendar i am using the Kal open source framework (http://github.com/klazuka/Kal)

I am currently trying to add an event creation button to add events (exactly like the "+" button on the original iphone calendar!)

Could someone please be kind enough to show how i should do this?

NOTE: In order to make my question as easy as possible, i am using the "NativeCal" example project that comes with the Kal framework, which does exactly what i want.
