UIDocumentInteractionController remove Actions Menu

I've been working with the Apple sample code for viewing documents from here:

https://developer.apple.com/library/ios/samplecode/DocInteraction/Listings/ReadMe_txt.html

I have removed all the bits I don't need and got it working pretty much how I would like it to. The problem is I don't want users to have access to the "Actions" menu on the top right of the Document Controller. This appears every time you select a document from the list:

Ideally I would like to remove the button all together, though if I could disable it or disable all the options inside it that would also suffice. I found this question:

Open in + UIDocumentInteractionController : how to filter options in SDK iOS 6 (canPerformActions is deprecated)

But I couldn't figure out how to use the suggestion to disable the options inside the menu. I have uploaded the modified sample code here:

One final note is this will not be going on the App Store it is for private, personal use, so if there is an unofficial way then I would be interested in knowing that too.

Any help would be greatly appreciated, thanks in advance.

Use UINavigationControllerDelegate

@interface DITableViewController () <UIDocumentInteractionControllerDelegate, UINavigationControllerDelegate>

Assign navigationController delegate to self

- (void)viewDidLoad {

    [super viewDidLoad];
    self.navigationController.delegate = self;
}

Change documentInteractionControllerViewControllerForPreview

- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)interactionController {

    return self.navigationController;
}

Add this UINavigationControllerDelegate method

// Called when the navigation controller shows a new top view controller via a push, pop or setting of the view controller stack.
- (void)navigationController:(UINavigationController*)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {

    if ([viewController isKindOfClass:[QLPreviewController class]]) {
        viewController.navigationItem.rightBarButtonItem = nil;
    }
}

Update for MP4 files

In MP4 files the action button is on the UIToolbar

- (void)navigationController:(UINavigationController*)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
    if ([viewController isKindOfClass:[QLPreviewController class]]) {
        viewController.navigationItem.rightBarButtonItem.customView = [[UIView alloc] init];
        UIBarButtonItem *item = viewController.toolbarItems.firstObject;
        item.customView = [[UIView alloc] init];
    }
}

N.B. This might not work in future versions of iOS
