how do I protect my iOS app from being cracked?
I'm trying to make my first app and it should cost about 10$. I'm afraid, that a lot of 'hackers' would crack my app and make it totally free. I found a lot of cracked apps in the web. Have you any ideas, how I can fix this problem?

Old question: how do I protect my iOS app from being cracked?
Answer:
It's very easy with little class, which I implemented: https://github.com/itruf/crackify
Just import Crackify.h and check:
BOOL cracked = [Crackify isCracked];
