how do I protect my iOS app from being cracked? [closed]

Question

I have $0.99 iOS app and I'm afraid someone would like to crack it. How can I protect my app from crackers?

Answer 1

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];

Answer 2

these are some check list to check whether your app is cracked.

1. checking plist size
2. checking signer identity
3. checking if binary is crypted
4. checking modified date of info.plist against modified date of package
