iOS 6 UIGestures (Tap) stops working with QLPreviewController

Currently I'm using a QLPreviewController in a navigation controller. (pushViewController)

To hide the navigationbar I use a UITapGestureRecognizer. The user can show/hide the navigation bar by a single touch (tap). This worked well in iOS5

- (void)viewWillAppear:(BOOL)animated {
   [super viewWillAppear:animated];

   UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)];
   [tapRecognizer setNumberOfTapsRequired:1];
   [tapRecognizer setDelegate:self];
   [[self view] addGestureRecognizer:tapRecognizer];
   [tapRecognizer release];
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    return YES;
}

- (void)tapped:(UIGestureRecognizer*)gestureRecognizer
{
    //hide -/- show navigation bar
    [[self navigationController] setNavigationBarHidden:![[[self navigationController] navigationBar] isHidden] animated:YES];
}

But in the released version of iOS 6 the taps are now completely ignored, so I can't hide my navigation bar anymore.

Reason why I want to hide the navigation bar?

If you open a .numbers document, the navigationbar hides the 'sheet-buttons' under the navigation bar.

since ios 6 the QLPreviewController is actually a completely seperate app (seperate process and everything)

Apple uses XPC for that:

=> so when you push that, your whole app moves to the bg, including its window and gesture recognizers
