I wanted to know if I can hide the Action button on the UIDocumentInteractionController so a user couldn\'t actually open the document in another app?
The whole purpose of the UIDocumentInteractionController is to show the user which applications can handle a file and give them a way to 'send' the file to the app they choose. Since hiding/disabling the button would confuse the user, I doubt it is possible (at least not without resorting to undocumented method calls).
