如何在SwiftUI中为textField制作“编辑”按钮？

@State private var isEditing = false

Button(action: {
    isEditing.toggle()
}) {
    Text("编辑")
}

TextField("输入文本", text: $text)
    .disabled(!isEditing)

import SwiftUI

struct ContentView: View {
    @State private var isEditing = false
    @State private var text = ""

    var body: some View {
        VStack {
            TextField("输入文本", text: $text)
                .disabled(!isEditing)
                .padding()
            
            Button(action: {
                isEditing.toggle()
            }) {
                Text(isEditing ? "完成" : "编辑")
                    .padding()
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(10)
            }
        }
    }
}

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