如何让一个按钮(或任何其他元素)在点击时显示SwiftUI的DatePicker弹出窗口？

@State private var isShowingDatePicker = false

Button(action: {
    isShowingDatePicker.toggle()
}) {
    Text("Show DatePicker")
}

if isShowingDatePicker {
    Group {
        DatePicker(selection: $selectedDate, in: ...Date(), displayedComponents: .date) {
            Text("Select a date")
        }
        .padding()
        .background(Color.white)
        .cornerRadius(10)
        .shadow(radius: 5)
        .transition(.opacity)
        .animation(.easeInOut)
    }
}

import SwiftUI

struct ContentView: View {
    @State private var isShowingDatePicker = false
    @State private var selectedDate = Date()
    
    var body: some View {
        VStack {
            Button(action: {
                isShowingDatePicker.toggle()
            }) {
                Text("Show DatePicker")
            }
            .padding()
            
            if isShowingDatePicker {
                Group {
                    DatePicker(selection: $selectedDate, in: ...Date(), displayedComponents: .date) {
                        Text("Select a date")
                    }
                    .padding()
                    .background(Color.white)
                    .cornerRadius(10)
                    .shadow(radius: 5)
                    .transition(.opacity)
                    .animation(.easeInOut)
                }
            }
        }
    }
}

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