SwiftUI -如何检测按钮上的长按？

import SwiftUI

struct ContentView: View {
    @State private var isLongPressing = false
    
    var body: some View {
        Button(action: {
            // 按钮点击事件
        }) {
            Text("按钮")
                .padding()
                .background(isLongPressing ? Color.red : Color.blue)
                .foregroundColor(.white)
        }
        .gesture(
            LongPressGesture(minimumDuration: 1.0)
                .onChanged { _ in
                    isLongPressing = true
                    // 长按操作开始
                }
                .onEnded { _ in
                    isLongPressing = false
                    // 长按操作结束
                }
        )
    }
}

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