Disable action items in UIDocumentInteractionController's presentPreviewAnimated

I am using UIDocumentInteractionController's presentPreviewAnimated method to preview document. It works fine. But I wish to disable the action button while in the preview mode. I have the following two delegated methods to return NO. But these two methods never got called at all. The other delegated methods work fine. Any suggestion?

-(BOOL)documentInteractionController:(UIDocumentInteractionController *)controller canPerformAction:(SEL)action {
NSLog(@"canPerformAction");
return NO;
}

and

-(BOOL)documentInteractionController:(UIDocumentInteractionController *)controller performAction:(SEL)action {
NSLog(@"performAction");
return NO;
}
Solution

  • I finally switched to use the QLPreviewController class. Where you can subclass it and make the action button gone away. (With the help from the answer by rbrown of this SO.
