import SwiftUI

struct ContentView: View {
    @State private var buttonColors: [Color] = [.red, .green, .blue]

    var body: some View {
        VStack {
            ForEach(buttonColors.indices, id: \.self) { index in
                Button(action: {
                    // 在此处更改按钮颜色
                    self.buttonColors[index] = .yellow
                }) {
                    Text("按钮 \(index + 1)")
                        .foregroundColor(.white)
                        .padding()
                        .background(buttonColors[index])
                        .cornerRadius(10)
                }
                .padding()
            }
        }
    }
}

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