Create a Transparent NavigationBar

Question

I am wondering how do we create a UINavigationBar that is totally transparent (alpha = 0) but the BarButton Item is still visible.

I would like to have an Invisible NavigationBar but I need the BarButtonItem to be visible.

Screenshot

Swift

self.navigationController?.navigationBar.setBackgroundImage(UIImage.new(), forBarMetrics: UIBarMetrics.Default)
self.navigationController?.navigationBar.shadowImage = UIImage.new()

OC

[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setShadowImage:[UIImage new]];
