How to create an OSX Calendar event with an "open file" alarm

Hello Devs!

I have searched the doco and the Internet for a few days now....

I must be missing something? - I cant, for the life of me, find a way to create an OSX calendar event with an "open file
alarm using code (Objective-C) from my Cocoa app.

I'm actually getting the feeling it cant be done!


(For my current use-case, the Calendar really does make sense - so I would much prefer it over other options like Launchd etc)


As a side note: I have found some examples for Applescript (but even those fail on OSX >= 10.9)

Cheers for any tips!

Dan
