Apps know when they're cracked

Lately i have noticed that many apps know when they have been cracked. (i was pm'd the screen shots of the errors received, i don't use cracked ipas). I am currently working on my own game for the app store and was wondering how to implement a "security" feature like this in my app. I was thinking it was made with the missing DRM file that is deleted during cracking but i am unsure. If anyone could provide some help i would greatly appreciate it.

You are not pretty enough to be that stupid.

I have read many threads on this, with developers suggesting its not worth it due to the fact that the crackers now have ways of patching the cracked version... Its up to you, but it will eventually get cracked by someone

Not sure how its done, something about using plist but here

Again, any of the apps listed will, guaranteed, be compromised in the next few days
