Ios 如何删除NavigationView中的默认透明标头

在iOS 16中，您可以使用此修饰符隐藏Destination上的导航栏:

.toolbarBackground(.visible, for: .navigationBar)

并使其具有如下所示的定制 colored颜色 :

.toolbarBackground(.red, for: .navigationBar)

以下是完整的代码:

struct Home: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: DetailView().toolbarBackground(.hidden, for: .navigationBar)) {
                    Text("Go to detail view (hidden navigation)")
                }
                NavigationLink(destination: DetailView().toolbarBackground(.orange, for: .navigationBar)) {
                    Text("Go to detail view (orange navigation)")
                }
            }
        }
    }
}

struct DetailView: View {
    var body: some View {
        VStack {
            ScrollView(.vertical, showsIndicators: false) {
                Circle().fill(.red)
                Circle().fill(.blue)
                Circle().fill(.yellow)
                Circle().fill(.green)
            }
        }
    }
}
