You could salt and encrypt the data before putting it in NSUserDefaults. Or use the iOS keychain. But nothing is secure against someone capable of disassembling and reverse engineering your app's code.

Thanks!!!

Ok, i think i will do that encrypting the data before saving it...But how can i do that??

Btw I've googled how to and can't find the solution for that( But I really want to know this because it's the final thing I gotta do with my app before submitting it...

i appreciate it!

Edit: I got it... I wanted to save my integers, so I converted so integers to strings and then to data which I encrypted, then saved it and it can't really be changed by the users.. So thanks for the tip Firewood!
