objective c - Transfer/Copy files from one iPad app to another iPad app for Editing -


i wondering if there way in objective c have ipad app copy file in it's documents folder app's documents folder , have app open file editing , copy file documents folder. or better yet, can have app open file documents folder, edit file, , save documents folder?

so far know can have app open file in documents folder app i'm handing document off seems making local copy , editing copy. know each app's document folder shared folder users can drag , drop stuff itunes i'm not sure if same can done in code.

i pretty sure trying impossible. ios applications "sandboxed" means each app has own documents directory. no application has access file system outside own "sandbox" i.e. outside own local documents directory.
