如何根据推流通知的类型打开Viewcontroller？

// 监听推流通知的回调函数
func handlePushNotification(notification: PushNotification) {
    switch notification.type {
    case .liveStreamStarted:
        // 推流开始通知，打开直播界面
        let liveViewController = LiveViewController()
        navigationController?.pushViewController(liveViewController, animated: true)
    case .liveStreamEnded:
        // 推流结束通知，返回上一个界面
        navigationController?.popViewController(animated: true)
    case .liveStreamError:
        // 推流错误通知，显示错误提示界面
        let errorViewController = ErrorViewController()
        present(errorViewController, animated: true, completion: nil)
    default:
        break
    }
}
