The problem is that it is a private class that you can't test against.

Fortunately _UIPopoverSlidingChromeView is the subclass of UIPopoverBackgroundView that is public (because in regular popover implementation flow client may customize the popover background chrome by providing a class which subclasses UIPopoverBackgroundView).

for (UIView *subview in self.viewController.view.superview.superview.subviews) {

        subview.alpha = 0.0;
    }
}
