使用SwiftUI。单击后，“我的滑块/侧面菜单”会启动新视图，但单击按钮，现在所有选项均为'dead'

Question

使用SwiftUI和我增加的滑块/侧边菜单教程，以便对每个侧边菜单选择进行操作。

显示侧边菜单并点击菜单选项时，它的效果很好，可将我带到带有菜单项的新视图。但是，当我点击并看到侧面菜单仍然存在时，所有菜单项都没有消失。菜单项仍然可以使点击动起来（闪烁），但是什么也没有发生。我必须关闭侧面菜单，然后重新打开，然后菜单项再次起作用-一次。

谁能告诉我为什么会这样吗？

这里是漂亮的contentview，mainview和sidemenu视图。

//ContentView.swift

import SwiftUI

struct ContentView: View {

    @State var showMenu = false

var body: some View {

    let drag = DragGesture()
        .onEnded {
            if $0.translation.width < -100 {
                withAnimation {
                    self.showMenu = false
                }
            }
        }

    return NavigationView {
        GeometryReader { geometry in
            ZStack(alignment: .leading) {
                MainView(showMenu: self.$showMenu)
                    .frame(width: geometry.size.width, height: geometry.size.height)
                    .offset(x: self.showMenu ? geometry.size.width/2 : 0)
                    .disabled(self.showMenu ? true : false)
                if self.showMenu {
                    MenuView()
                        .frame(width: geometry.size.width/2)
                        .transition(.move(edge: .leading))
                }
            }
                .gesture(drag)
        }
            .navigationBarTitle("Side Menu", displayMode: .inline)
            .navigationBarItems(leading: (


                   Button(action: {
                        withAnimation {
                            self.showMenu.toggle()
                        }
                    }) {
                        Image(systemName: "line.horizontal.3")
                            .imageScale(.large)
                    }
                ))
        }
    }
}

struct MainView: View {

    @Binding var showMenu: Bool

    var body: some View {
        Button(action: {
            withAnimation {
               self.showMenu = true
            }
        }) {
            Text("Show Menu")
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

这是侧面菜单视图。

//MenuView.swift

import SwiftUI


struct PlayerView: View {
    @State var showMenu = true
    //@EnvironmentObject var session: SessionStore

    var body: some View {
        VStack{
            //self.showMenu = true
            Text("Manage Players Here").foregroundColor(.red)

         }
    }
}


struct MenuView: View {
    @State var showMenu = true


    var body: some View {

        VStack(alignment: .leading) {

            HStack() {

                NavigationLink(destination: PlayerView()) {
                    HStack(){
                        Image(systemName: "person")
                           .foregroundColor(.gray)
                           .imageScale(.large)
                        Text("Players")
                        .foregroundColor(.gray)
                        .font(.headline)
                    }
                }
            }
            .padding(.top, 100)

            }
            .padding()
            .frame(maxWidth: .infinity, alignment: .leading)
            .background(Color(red: 32/255, green: 32/255, blue: 32/255))
            .edgesIgnoringSafeArea(.all)
    }
}


struct MenuView_Previews: PreviewProvider {
    static var previews: some View {
        MenuView()
    }
}
