Below is the detailed steps:

(For example, we have 2 Apps)

App1 creates a file anywhere in its sandbox.

App1 CILS docinteraction to display the "open in" GUI for that file

User picks "open in app2"

The IOS copies the file from one sandbox to the other and launches app2.

App2 implements didfinishlaunchingwithurl and loads the supplied URL (which is the copy in its sandbox)
