SwiftUI 与 UIKit框架的交互

MapView

struct MapView: UIViewRepresentable {
    
    func makeUIView(context: Context) -> MKMapView {
        MKMapView(frame: CGRect.zero)
    }
    
    func updateUIView(_ uiView: MKMapView, context: Context) {
        let coordinate = CLLocationCoordinate2D(
          latitude: 34.011286, 
          longitude: 116.166868
        )
        let span = MKCoordinateSpan(latitudeDelta: 2, longitudeDelta: 2)
        let region = MKCoordinateRegion(center: coordinate, span: span)
        uiView.setRegion(region, animated: true)
    }
}

struct MapView_Preview: PreviewProvider {
    static var previews: some View {
        MapView()
    }
}
