从 iOS 应用程序调用具有多个目的地的谷歌地图

import UIKit
import GoogleMaps

class ViewController: UIViewController {

  override func viewDidLoad() {
    super.viewDidLoad()

    // 设置谷歌地图 API 密钥
    GMSServices.provideAPIKey("YOUR_API_KEY")

    // 创建地图视图
    let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 6.0)
    let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
    view = mapView

    // 添加多个目的地
    let destination1 = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
    let destination2 = CLLocationCoordinate2D(latitude: -33.92, longitude: 151.28)

    // 创建标记
    let marker1 = GMSMarker(position: destination1)
    marker1.title = "Destination 1"
    marker1.map = mapView

    let marker2 = GMSMarker(position: destination2)
    marker2.title = "Destination 2"
    marker2.map = mapView
  }
}
