Are NSUserDefaults hackable?

[sumosumo84]

I posted a similar thread on this and got a great answer, which was to hash the values i want to protect.

Well i made my own hash up and it works great!

But i am really afraid that if i release the app, there might be a glitch and the "before hash" and "after hash" values won't match when they are supposed to.

I really don't want to have to hash the values.

I won't need to either if i can be certain that an average person cannot hack NSUserdefault values.

I would rather let 100 people change their values than have 1 person get glitched and have to start over.
