iphone - Saving game score locally on iOS device...is security needed? -


do need store score hash, ie protect being edited/cheated user? newb knowledge, user unable view , manipulate locally stored data, plist files example. can elaborate?

[edit] i'm storing scores locally , periodically uploading them game center leaderboards. if device jailbroken i'd have security prevent scores being manipulated user. approach?

i this:

save in nsdictionary , convert nsdata object. comes cool part:

encrypt aes using class:

this military standard encryption return encrypted nsdata object. save file , read/write whenever necessary. i've had experiences class , user can't it.

much better storing in plain sight using nsuserdefaults.

give go!
