SwiftUI -如何在编辑模式下更改列表的背景

import SwiftUI

struct ContentView: View {
    @State private var items = ["Item 1", "Item 2", "Item 3"]
    @State private var isEditing = false
    
    var body: some View {
        NavigationView {
            List {
                ForEach(items, id: \.self) { item in
                    Text(item)
                }
                .listRowBackground(Color.blue) // 在编辑模式下设置列表的背景为蓝色
            }
            .navigationBarTitle("List")
            .navigationBarItems(trailing: EditButton())
            .environment(\.editMode, $isEditing)
        }
    }
}

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