Ios App&x27；s Firebase推送通知在iPhone上成功，但在iPad上失败

我正在将Firebase推送通知用于我的应用程序的推送通知。对于使用iphone的用户来说，一切正常，但对于使用ipad的用户来说，一切都失败了。下面是我如何实现它的。是否有一些错误或需要补充的内容？多谢各位

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
let db = SQLiteDB.shared
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    completionHandler([.alert, .badge, .sound])
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    _ = db.open()
    
    FirebaseApp.configure()
    UNUserNotificationCenter.current().delegate = self
    
    if #available(iOS 10.0, *) {
        // For iOS 10 display notification (sent via APNS)
        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization( options: authOptions,completionHandler: {_, _ in })
    } else {
        let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)
    }
    application.registerForRemoteNotifications()
    print("Messaging.messaging().fcmToken= ",Messaging.messaging().fcmToken)
    return true
}
........

}

扩展AppDelegate:MessagingDelegate{ func消息传递（u消息传递：消息传递，didReceiveRegistrationToken fcmToken:String）{ let dataDict:[String:String]=[“token”：fcmToken] NotificationCenter.default.post（名称：Notification.name（“FCMToken”），对象：nil，用户信息：dataDict） } func消息传递（uMessaging:messaging，didReceive remoteMessage:MessagingRemoteMessage）{ } func应用程序（application:UIApplication，DidRegisterForRemotionTificationswithDeviceToken deviceToken:Data）{ Messaging.Messaging（）.apnsToken=deviceToken } func userNotificationCenter（center:UNUserNotificationCenter，didReceive响应：UNNotificationResponse，withCompletionHandler completionHandler:@escaping（）->Void）{ 让application=UIApplication.shared 如果application.applicationState==.active{ 打印（“用户点击前台的通知”） } 如果application.applicationState==.inactive{ 打印（“用户在后台点击通知”） } 让userInfo=response.notification.request.content.userInfo guard let aps=userInfo[“aps”]as？Dictionary else{return} completionHandler（） } }

extension AppDelegate : MessagingDelegate {

func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
    let dataDict:[String: String] = ["token": fcmToken]
    NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
}
func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
    
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Messaging.messaging().apnsToken = deviceToken
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    let application = UIApplication.shared
    if application.applicationState == .active {
        print("user tapped the notification in foreground")
    }
    if application.applicationState == .inactive {
        print("user tapped the notification in background")
    }
    let userInfo = response.notification.request.content.userInfo
    guard let aps = userInfo["aps"] as? Dictionary<String, Any> else { return }
    completionHandler()
