Calendar event attached to email

Hi
I am wondering how to attach a calendar event to an email in xcode...

I created an EKEventStore and then added a EK Event in that event store.
I am trying to add the event to the email using this code

Code:

        [controller addAttachmentData:myData mimeType:@"fileType" fileName:eventStartDateTitle];

My question is how can I take the EKEvent and put it into an object that will be compatible with addAttachmentData.

 

Creating an .ics file

Does anybody know the best route to take to create an .ics file in Xcode ?

 

Yes I am talking about a iCalendar Event. I am trying to attach the event to an email...
