Many iOS apps are able to share documents with other apps using the ‘Open in…’ command. For example, if an email includes a PDF as an attachment, the ‘Open In…’ menu will be populated with a list of all the apps that can view PDFs. If you would rather keep your apps sandboxed, iOS 7.0 now allows you to restrict which apps appear in the ‘Open In…’ menu, so you could, for example, ensure that only the PDF viewer you have installed can be used for viewing and saving PDFs and vice versa, so that data from corporate apps can never go public.
