透明導航欄 iOS 13

Question

無法創建透明 NavigationBar iOS 13。

我有自定義 UINavigationBar，我在其中配置 UINavigationBarAppearance

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

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

配置代碼：

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

並將其設置為：

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

結果我有這個：

預期結果：NavigationBar 應該是透明的

Answer 1

為我工作：

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

Answer 2

將外觀代碼修改為：-

let appearance = UINavigationBarAppearance()
appearance.configureWithTransparentBackground()
appearance.shadowColor = .clear
appearance.backgroundColor = .clear
appearance.backgroundImage = nil
appearance.shadowImage = nil
