ios - 将导航栏标题文本更改为自定义颜色？

Question

我正在尝试在我的 appDelegate 中使用以下代码将标题栏文本更改为自定义淡紫色阴影

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor(red: 0.9069682956, green: 0.7839415669, blue: 0.9612388015, alpha: 1)]

    return true
}

但是标题栏文本仍然显示为黑色。有没有更好的方法来改变这个？

可能还为时过早，请尝试在 ContentView 的 init 中添加，并添加一些大标题(SwiftUI NavigationView 的默认值)，例如

struct ContentView: View {

    init() {
        UINavigationBar.appearance().titleTextAttributes = 
            [NSAttributedString.Key.foregroundColor: 
               UIColor(red: 0.9069682956, green: 0.7839415669, blue: 0.9612388015, alpha: 1)]
        UINavigationBar.appearance().largeTitleTextAttributes = 
            [NSAttributedString.Key.foregroundColor: 
               UIColor(red: 0.9069682956, green: 0.7839415669, blue: 0.9612388015, alpha: 1)]
    }

    // ... other code with NavigationView here
}

使用 Xcode 12.1/iOS 14.1 进行测试
