将返回按钮添加到 UINavigationBar SwiftUI

Question

出于 this post 中概述的原因，我必须自定义导航栏，但 SwiftUI 现在不会自动为我生成后退按钮。如何添加它们？

查看我的示例代码：

struct ContentView: View {

init() {
    
    let coloredAppearance = UINavigationBarAppearance()
    coloredAppearance.configureWithOpaqueBackground()
    coloredAppearance.backgroundColor = .white
    coloredAppearance.titleTextAttributes = [.foregroundColor: UIColor.black]
    coloredAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.black]
    
    UINavigationBar.appearance().standardAppearance = coloredAppearance
    UINavigationBar.appearance().compactAppearance = coloredAppearance
    UINavigationBar.appearance().scrollEdgeAppearance = coloredAppearance
    
    UINavigationBar.appearance().tintColor = .white
}
    var body: some View {
        NavigationView {
            NavigationLink(destination: NavigationLink(destination: Color.purple) {
                Text("Continue")
                    .navigationTitle("Nav Title 2")
                    .navigationBarTitleDisplayMode(.inline)
            }) {
                Text("Continue")
                    .navigationTitle("Nav Title 1")
                    .navigationBarTitleDisplayMode(.inline)
            }
        }
    }
}

在您的示例代码中，生成了后退按钮，但颜色为白色，因此它们在导航栏中不可见。

要显示后退按钮更改：

UINavigationBar.appearance().tintColor = .white

收件人：

UINavigationBar.appearance().tintColor = UIColor(.accentColor)
