UINavigationBar.appearance().shadowImage = UIImage() in swif

Question

如何在Swift 4或Xcode 9中实现此代码？

// Remove hairline between navigation bar and anything below such as search bar
UINavigationBar.appearance().shadowImage = UIImage()

我想删除Navbar下划线。

Answer 1

不用担心复制粘贴会起作用。

// Remove Bottom Shadow
UINavigationBar.appearance().shadowImage = UIImage()
UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .default)

Answer 2

请检查：

self.navigationController?.navigationBar.shadowImage = UIImage()
