Swift 如何让 UITabBar 变得模糊

Question

我正在尝试使 UITabBar 看起来模糊。 I am trying to make something like this in this image 但我的观点现在看起来像这样 This is my view for tabbar

我在 UITabbarController 中尝试了这段代码 -

Code:
class TabBarViewController: UITabBarController { 
    override func viewDidLoad() {
        super.viewDidLoad()
        configureTabbar()
    }
    
    func configureTabbar(){
        
        
        let blurEffect = UIBlurEffect(style: .dark)
        let vibrancyEffect = UIVibrancyEffect(blurEffect: blurEffect)

        let vibrancyView = UIVisualEffectView()
        vibrancyView.frame = tabBar.bounds
        vibrancyView.autoresizingMask = .flexibleWidth
        vibrancyView.effect = vibrancyEffect
        tabBar.insertSubview(vibrancyView, at: 0)
        
        tabBar.isTranslucent = true
        tabBar.backgroundImage = UIImage()
        tabBar.backgroundColor = .clear
        tabBar.barStyle = UIBarStyle.black
        tabBar.barTintColor = UIColor.clear
}

Answer 1

UINavigationBar、UITabBar 和 UIToolbar 等系统栏默认是半透明的，您不需要添加任何额外的东西来获得这种效果。

您只需要确保您的视图在系统栏下扩展它的内容。您可以转到情节提要并确保为您计划在其上看到此效果的 UIViewController 检查 Extend Edges - Under Bottom Bars。
