Prohibit exporting or sharing documents in UIDocumentBrowserViewController

Question

Is there any way to prohibit exporting files in my UIDocumentBrowserViewController-based application that also provides a FileProvider?

• The user should only be allowed to view and edit files in the app.
• The user should be able to move files around within the FileProvider resource, add new folders, ...

Context:

• I'm building an enterprise app that grants access to a network file system with sensitive information.
• I'm using a FileProvider extension that only can be used inside my app.
• I thought of achieving this via the FPUIActionExtensionViewController by throwing authentication errors if the FileProvider is being accessed from other apps.
• I want to avoid building my own UI and use the one that Apple provides for free.

Answer 1

No, not really. Neither would it make sense to have such a control since taking a screenshot is trivial, and even if you could disable that, taking a photo of the screen is still possible.

Answer 2

Yes, this is built-in. Make your app a managed enterprise app ; then you can control access to the files with configuration profiles.
