问题
I was wondering how I can change the icons that show up in the table view.
I looked at the documentation for UIDocumentInteractionController on apple.com but I didn't have any success editing my plist. If someone knows how to do this please help.
Thank you

Registering the File Types Your App Supports describes how to register custom file types together with their icons in an app.
So if you use "com.example.myformat" as UTI type in the LSItemContentTypes array of the plist, and set the UTI property of the document interaction controller to the same string "com.example.myformat", then your icon should be used.
