How do I associate file types with an iPhone application?

After some Googling, I found I was to change my plist file to include “Document Types” —> an array with two values in each spot: Document Type Name, Handler Rank.

I did this and wrote public.pdf, public.png, etc… as the document type names and I tried every available handler rank. However, when I test it on the iPad, my app still will not display in the “Open in…” list.

Can anyone help me to achieve this?

Answer 1

I have not tested, but does this work for you?
