Ios FCM推送通知如何获取数据和显示自定义横幅

我正在开发小应用程序，我想向我的应用程序发送推送通知。一切都安排好了。而且工作很好。但是现在我想发送自定义通知，并显示接收fcm推送通知时显示的自定义横幅

我在安卓系统中很容易做到这一点，但在iOS中我有一些困惑。这里有一些我没有得到的东西，我不知道该做什么

我想要的：以下是我的应用程序要求：

• 我想展示定制横幅
• 我想解析服务器发送的数据并保存在UserDefaults中

我在做什么：我正在从服务器发送推送并接收横幅，但它显示了正文中的所有数据，下面是我的应用程序代理

我的服务器发送的结构如下，我想显示来自{body}标记的一些数据

注意：我希望该应用程序在前台、后台甚至关闭时显示相同的横幅

没人知道吗？你能告诉我你是如何为android制作横幅的吗

    extension AppDelegate: UNUserNotificationCenterDelegate {

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print("Did Receive")
    completionHandler()
}

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    print("Will Present")
}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    print("Did Receive remote notification")
}


func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    print("Did Receive device token")
}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

}

/// Register for push notifications
func registerForPushNotification(){

    if #available(iOS 10.0, *) {
        let center  = UNUserNotificationCenter.current()
        center.delegate = self
        center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
            if error == nil{
                DispatchQueue.main.async {
                    UIApplication.shared.registerForRemoteNotifications()
                }
            }
        }
    } else {

        let settings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        UIApplication.shared.registerUserNotificationSettings(settings)
        UIApplication.shared.registerForRemoteNotifications()
    }
}
