被iOS 6上的EventKit框架欺负

Question

At first I though I had left my self this message, but then I started seeing more comments like this one. I just want to ask if Im the only one seeing messages like this ? I think its funny in some way, but it left me wondering if I'd got a rogue SDK

 2012-11-10 13:15:53.736 myApp[1419:907] *** -[__NSCFCalendar components:fromDate:]: date cannot be nil
I mean really, what do you think that operation is supposed to mean with a nil date?
An exception has been avoided for now.
A few of these errors are going to be reported with this complaint, then further violations will simply silently do whatever random thing results from the nil.

Answer 1

You are not the only one who has seen this. That's an official SDK message; programmer who wants to tell you what you're doing wrong, straight! You're safe to continue.
