Question

我对导航链接和SwiftUI有问题。导航栏消失，我的滚动视图上升。我已在以下链接的Facebook上上传了有关该问题的视频：the link of the video

这是我主要视图的代码：

    struct MainView: View {

    let date = Date()
    let calendar = Calendar.current


    static let formatter: DateFormatter = {


        let formatter = DateFormatter()

        formatter.dateStyle = .medium

        formatter.timeStyle = .short

        return formatter

    }()

    //MARK: Properties
    @ObservedObject var session = FirebaseSession()

    let user = Auth.auth().currentUser

    @State private var showModal = false

    var body: some View {
        NavigationView{
           // Group {

                ZStack {
                if session.session != nil {
                    ScrollView {
                        VStack{
                            ScrollView(.horizontal, showsIndicators: false){
                                HStack{
                                    NavigationLink(destination: RedactorView()) {
                                    RedactorListItem()
                                             }.buttonStyle(PlainButtonStyle())
                                     RedactorListItem()
                                     RedactorListItem()
                                     RedactorListItem()
                                     RedactorListItem()
                                     RedactorListItem()
                                }//.padding()
                            }
                            VStack(alignment: .leading, spacing: 5) {
                                HStack {
                                    Text("Les derniers médias")
                                    .font(.largeTitle)
                                    .bold()

                                MediaListRow()
                                    .frame(width: UIScreen.main.bounds.width/1.15)

                                    .scaledToFit()
                                MediaListRow()
                                    .frame(width: UIScreen.main.bounds.width/1.15)
                                    .scaledToFit()
                                MediaListRow()
                                    .frame(width: UIScreen.main.bounds.width/1.15)
                                    .scaledToFit()

                            }
                        }
                        Text("Ses Articles :")
                            .font(.largeTitle)
                            .bold()
                            .padding(.leading)

                        ArticleListRow()
                        ArticleListRow()
                        ArticleListRow()
                    }
                }.navigationBarTitle("Redactor")

           }
       // }//.padding(.top, -20)
    }
}

我不知道该怎么解决，我希望它能正常打开，但找不到，并且所有滚动视图都相同。请帮我。

在navigationView上缺少.edgesIgnoringSafeArea(.top)，可以为您提供safeArea防护。
