I want to be able to provide a number of files which users can select and then load into my app. My app defines the extensions it can load and this works fine if a file with that extension is emailed to a user, they get the option to open it in the app. What I now want to do, is allow them to go to my web site and download files and open them in the app. However when I test a link I have embedded in my site Safari downloads it, and then just displays its contents (which text JSON). If I select the share icon I do not get my app as an option to share the file with. How can I set this up to work?
