如何在ios sdk中识别特定通知

import UserNotifications

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
    if granted {
        DispatchQueue.main.async {
            UIApplication.shared.registerForRemoteNotifications()
        }
    }
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    let userInfo = response.notification.request.content.userInfo
    if let aps = userInfo["aps"] as? [String: AnyObject], let alert = aps["alert"] as? [String: AnyObject], let title = alert["title"] as? String {
        // 处理特定通知
    }
    completionHandler()
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    if let userInfo = launchOptions?[.remoteNotification] as? [String: AnyObject] {
        // 处理特定通知
    }
    return true
}
