How to encrypt to the savedata on iOS?
I think very nice if the AES Fusion object is usable. But, it's not compatible to iOS.
Is there available another string encryption object on iOS?

I tend to just save data to an array file. It is stored as binary, so it is not simple to read and modify. If the user is a hacker who can read it, they probably can break any encryption you have anyway.

Also, Game Center is very easy for hackers to post fake high scores. It is a problem you just need to accept, unfortunately.
