在ios15的导航栏添加阴影

Question

我试图在导航栏上应用阴影，但是我所有的尝试都失败了。我找到了一个有效的解决方案，但它不能在ios 15....上工作谁能解决类似的问题，并分享一个可行的解决方案吗?

它不能在ios 15上运行:

navigationController?.navigationBar.layer.shadowColor = UIColor.baseGray.cgColor
navigationController?.navigationBar.layer.shadowOffset = CGSize(width: 0.0, height: 2.0)
navigationController?.navigationBar.layer.shadowRadius = 10.0
navigationController?.navigationBar.layer.shadowOpacity = 0.25
navigationController?.navigationBar.layer.masksToBounds = false

我找到了一个解决办法，也许有人会觉得有用

func setupShadowNavigationBar() {
if #available(iOS 15, *) {
let navigationBarAppearance = UINavigationBarAppearance()
navigationBarAppearance.configureWithDefaultBackground()
UINavigationBar.appearance().standardAppearance = navigationBarAppearance
UINavigationBar.appearance().compactAppearance = navigationBarAppearance
UINavigationBar.appearance().scrollEdgeAppearance = navigationBarAppearance
}

navigationController?.navigationBar.layer.shadowColor = UIColor.baseGray.cgColor
navigationController?.navigationBar.layer.shadowOffset = CGSize(width: 0.0, height: 2.0)
navigationController?.navigationBar.layer.shadowRadius = 10.0
navigationController?.navigationBar.layer.shadowOpacity = 0.25
navigationController?.navigationBar.layer.masksToBounds = false
}
