I am implementing iOS Share Extension for my app, and I want to be able to get any kind of file into my app extension (e.g. a binary file of any type shared from Dropbox).
How can I achieve this behavior? loadItemForTypeIdentifier:options:completionHandler: expects a UTI, I've tried providing an empty string but it didn't work.
Solved my own problem. I've tried public.data for the UTI and it seems to work perfectly with any kind of file that I've tried.
