使用SwiftUI按钮操作切换Binding<Bool>

import SwiftUI

struct ContentView: View {
    @State private var isOn = false

    var body: some View {
        VStack {
            Text("Toggle: \(isOn.description)")
                .padding()

            Button(action: {
                self.isOn.toggle()
            }) {
                Text("Toggle Button")
                    .padding()
                    .background(Color.blue)
                    .foregroundColor(.white)
                    .cornerRadius(10)
            }
        }
    }
}

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