无法更改iOS 13中大标题的导航栏色调颜色

Question

代码：

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

        UINavigationBar.appearance().barTintColor = .red

        return true
    }

如果prefersLargetitles为false，则没有问题。但是，随着preferredsLargeTitles = true的出现，颜色不会改变。该功能过去曾在iOS 12上运行。但是，由于iOS 13不能正常运行。有人可以帮忙在iOS 13中自定义导航栏吗？

代码：func应用程序（_应用程序：UIApplication，didFinishLaunchingWithOptions launchOptions：[UIApplication.LaunchOptionsKey：任何]？）-> Bool {//自定义覆盖点...

Answer 1

if #available(iOS 13.0, *) {
    let appearance = UINavigationBarAppearance()
    appearance.backgroundColor = .purple
    UINavigationBar.appearance().compactAppearance = appearance
    UINavigationBar.appearance().scrollEdgeAppearance = appearance
} else {
    UINavigationBar.appearance().barTintColor = .purple
}
