隐藏SwiftUI中的导航栏

Question

我在SwiftUI中使用NavigationView时遇到了问题。我添加了以下代码以隐藏导航栏，但是当滚动视图时，会出现粘性标题。如何删除它？谢谢！

NavigationView {
...
}
.navigationBarTitle("")
.navigationBarHidden(true)
.navigationBarBackButtonHidden(true)

将navigationBarTitle和navigationBarHidden放在NavigationView内部会取消粘性标题。以下是代码。

import SwiftUI

struct ContentView: View {
    let months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December","January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]

    var body: some View {
        NavigationView {
            List(months, id: \.self) { month in
                NavigationLink(destination: DetailView(month: month)) {
                        Text(month)
                }
            }
            .navigationBarTitle("")
            .navigationBarHidden(true)
        }
        //.navigationBarBackButtonHidden(true)
    }
}

struct DetailView: View {
    let month: String
    var body: some View {
        Text(month)
    }
}
