xcode - Saving Data on iCloud -

i have been able sync plist icloud user's level high scores.

i still haven't been able figure out how make people cannot go icloud docs folder , change values.

i know jetpack joyride saves game information icloud, when go documents folder, there nothing in there (do save own servers?)

another game have saves "game.sav" file.

is there folder can save in icloud users cannot access? ruin game if change high score or achievement numbers game center.

thanks in advance!

instead of document-saving feature of icloud, use key-value feature of icloud (nsubiquitouskeyvaluestore). users can't see that.
