So I have learned to make a blurred effect according to post link. But that post does not issue how to make a blurred effect that also covers the TabBarController and NavigationController elements.
How can I make a blurred effect that covers the whole screen, including the TabBarController and NavigationController elements?
It's doing exactly what you ask right now, which is covering the entire view. That view, however, is of a child
UIViewController, which has its real estate managed by a parent view controller. Only this parent has its view covering the entire screen. So in the case of embedding in a
UINavigationController, you'd do instead:
blurEffectView.frame = self.navigationController!.view.bounds self.navigationController!.view.addSubview(blurEffectView)
