每次导航到另一个屏幕时，我都会在控制台中收到此消息：

[Assert] displayModeButtonItem is internally managed and not exposed for DoubleColumn style. Returning an empty, disconnected UIBarButtonItem to fulfill the non-null contract.

目前我在应用程序的入口点设置了导航视图，就像这样

NavigationView {
        KeyboardView(matrixVM: matrixVM, isNavigationBarHidden: $isNavigationBarHidden)
            .background(Color("background")
            .edgesIgnoringSafeArea(.all))
            .navigationBarTitle("Workspace")
            .navigationBarHidden(self.isNavigationBarHidden)
            .onAppear {
                self.isNavigationBarHidden = true
        }
    }

然后在 KeyboardView 里面我有导航链接

NavigationLink(destination: NotebookView(isNavigationBarHidden: $isNavigationBarHidden, saved: matrixVM), label: {
                            Text("Notebooks")
                                .font(.system(size: 14, design: .rounded))
                                .fontWeight(.medium)
                                .foregroundColor(Color("text"))
                                .padding(.trailing, 10)
                        })

在 NotebookView 中，我有一个导航链接列表（每个笔记本链接到其详细信息页面）

ScrollView(showsIndicators: false) {
                        ForEach(notebooks, id: \.self) { notebook in
                            
                            NavigationLink(destination: ExpandedSnippet(matrixVM: saved ,notebook: notebook)
                                            .navigationBarTitle("Notebook", displayMode: .inline)) …
