如何在用户未点击通知的情况下显示特定视图控制器

import UIKit
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // 注册远程通知和本地通知
        UNUserNotificationCenter.current().delegate = self
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
            // 处理授权结果
        }
        application.registerForRemoteNotifications()
        
        return true
    }

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        // 处理设备令牌
    }

    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        // 处理注册失败
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        // 获取通知内容
        let userInfo = notification.request.content.userInfo
        
        // 判断是否需要显示特定的视图控制器
        if let viewController = getSpecificViewController(userInfo: userInfo) {
            // 设置特定的视图控制器为根视图控制器
            window?.rootViewController = viewController
        }
        
        // 完成处理
        completionHandler([.alert, .sound, .badge])
    }
    
    func getSpecificViewController(userInfo: [AnyHashable: Any]) -> UIViewController? {
        // 根据通知的内容判断是否需要显示特定的视图控制器
        // 返回特定的视图控制器实例
        return nil
    }
}
