如何从我自己的原生应用程序中启动Google Maps iPhone应用程序？

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let openMapsButton = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
        openMapsButton.setTitle("打开Google Maps", for: .normal)
        openMapsButton.addTarget(self, action: #selector(openMaps), for: .touchUpInside)
        
        self.view.addSubview(openMapsButton)
    }
    
    @objc func openMaps() {
        if let url = URL(string: "comgooglemaps://") {
            if UIApplication.shared.canOpenURL(url) {
                UIApplication.shared.open(url, options: [:], completionHandler: nil)
            } else {
                // 提示用户未安装Google Maps应用程序
            }
        }
    }
}
