How to open a custom app from clicking 'view event' of calender reminder

I have set reminder event in a app using Eventkit framework. I used following link for creating 开发者_开发百科reminder in iCal. And also set alarm for the event. Now when alarm is displayed in alert view, while clicking 'View Event' button , nothing happens. How to open the app to show the notes saved when alert view button clicked? Thanks in advance.

Create a function that does that. And in action: just put the name of the function. That way, the action will be fired as soon as the alert button is tapped.
