The Apple guidelines say:
Apps that read or write data outside its designated container area will be rejected
What is their designed container area?
回答1:
Basically, it means that you should not write or read data to/from any other directory other than your own applcations directory.
e.g. you can update the sqlite DB of your another app from your own app unless there is a public API that allows that
回答2:
Each Application is bound by its directory where it is installed. Apple restricts you from accessing the contents of another App through its directory from your App.
