You can’t just browse all the files on the phone from within your App.

As I said to you in the comment on your other questions (which, by the way is almost exactly the same as this one, but in the other question you ask about csv files rather than pdf), you need to read up about the App Sandbox.

In a nutshell, Apps can only see their own files and those that are written by the App. All apps have their own storage space and they can only see in that area.

Having said that, it is possible to pass some files around between apps, but they have to be written to support that. There is no such concept as a global file system on iOS devices.
