使用SwiftUI将单个图钉添加到Mapkit

import SwiftUI
import MapKit

struct MapView: UIViewRepresentable {
    var coordinate: CLLocationCoordinate2D
    
    func makeUIView(context: Context) -> MKMapView {
        MKMapView(frame: .zero)
    }
    
    func updateUIView(_ view: MKMapView, context: Context) {
        let annotation = MKPointAnnotation()
        annotation.coordinate = coordinate
        view.addAnnotation(annotation)
        
        // 设置地图的显示区域
        let span = MKCoordinateSpan(latitudeDelta: 0.2, longitudeDelta: 0.2)
        let region = MKCoordinateRegion(center: coordinate, span: span)
        view.setRegion(region, animated: true)
    }
}

struct ContentView: View {
    let coordinate = CLLocationCoordinate2D(latitude: 37.332, longitude: -122.031)
    
    var body: some View {
        MapView(coordinate: coordinate)
            .frame(height: 300)
    }
}
