iOS透明导航栏13

Question

无法创建透明的NavigationBar iOS 13。

我有自定义UINavigationBar，在其中配置UINavigationBarAppearance

override init(frame: CGRect) {
    super.init(frame: frame)
    self.configure()
}

required init?(coder: NSCoder) {
    super.init(coder: coder)
    self.configure()
}

配置代码：

let appearance = UINavigationBarAppearance()
appearance.configureWithTransparentBackground()
appearance.shadowColor = .clear
appearance.backgroundColor = .clear

并将其设置为：

self.compactAppearance = appearance
self.standardAppearance = appearance
self.scrollEdgeAppearance = appearance

结果，我得到了这个：

预期结果：NavigationBar应该透明
