Can I hide the Action button on the UIDocumentInteractionController view?

Question

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?

Answer 1

I found something that works for me well enough:

- (BOOL)documentInteractionController:(UIDocumentInteractionController *)controller   canPerformAction:(SEL)action{
    return false;
}

It still shows the button but the popover that appears only has the print form but the print button is disabled.

Answer 2

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).
