如何在SwiftUI中隐藏选项卡栏特定视图中的导航栏？

struct HideNavigationBar: ViewModifier {
    func body(content: Content) -> some View {
        content
            .navigationBarTitle("")
            .navigationBarHidden(true)
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            TabView {
                FirstView()
                    .modifier(HideNavigationBar()) // 使用自定义修饰符隐藏导航栏
                    .tabItem {
                        Image(systemName: "1.circle")
                        Text("First")
                    }
                SecondView()
                    .tabItem {
                        Image(systemName: "2.circle")
                        Text("Second")
                    }
            }
        }
    }
}
