SwiftUI:用MapPin作为按钮替换自定义地图按钮？

import SwiftUI
import MapKit

struct MapView: View {
    var body: some View {
        Map(coordinateRegion: .constant(MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 37.331516, longitude: -122.03118), span: MKCoordinateSpan(latitudeDelta: 0.2, longitudeDelta: 0.2))))
    }
}

struct MapView: View {
    @State private var showDetails = false
    
    var body: some View {
        Map(coordinateRegion: .constant(MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 37.331516, longitude: -122.03118), span: MKCoordinateSpan(latitudeDelta: 0.2, longitudeDelta: 0.2)))) {
            MapPin(coordinate: CLLocationCoordinate2D(latitude: 37.331516, longitude: -122.03118), tint: .red)
                .onTapGesture {
                    self.showDetails.toggle()
                }
                .sheet(isPresented: $showDetails) {
                    // 在此处添加显示详情的代码
                }
        }
    }
}
