为什么我'；我无法在iOS 10中处理收到的推送通知？

我已经进口了

import UserNotifications

和关联代表：

UNUserNotificationCenterDelegate

并将代理设置为自己：

UNUserNotificationCenter.currentNotificationCenter().delegate = self
FIRMessaging.messaging().remoteMessageDelegate = self

最后，我有以下功能：

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    //Handle the notification
    print("User Info = ",notification.request.content.userInfo)
    completionHandler([.Alert, .Badge, .Sound])
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
    //Handle the notification
    print("User Info = ",response.notification.request.content.userInfo)
    completionHandler()
}

但当我在真实设备上和后台模式下进行测试时，我的日志上没有任何打印

有什么问题

internal func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    print(userInfo)

    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {        
    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")

    // Print full message.
    print(userInfo)
}

请尝试以下代码。你只需要保存数据

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> ())
{
     let info : NSDictionary! = userInfo as! NSDictionary

     if info != nil
      {
          let aps = info["aps"] as? NSDictionary
          UserDefaults.standard.set(aps, forKey: "aps")
       }
   }

并在要使用的位置使用用户默认值。

必须使用断点调试代码。如果此方法未调用DidReceiveMotonification。然后你必须检查后端。只有当我在应用程序中时，它才会调试。但是当我处于后台模式时，我收到通知，但无法处理@amanpretp请检查下面的答案。为什么要使用两种“DidReceiveEmotentification”方法？必须使用断点调试代码。如果此方法未调用DidReceiveMotonification。然后你必须检查后端。只有当我在应用程序中时，它才会调试。但是当我处于后台模式时，我收到通知，但无法处理@amanpretp请检查下面的答案。你为什么要使用两种“DidReceiveMemotentification”方法？看看我更新了我的答案。你可以在这里检查，当然你必须打电话给完成处理3R？？检查我已经更新了我的答案。您可以在这里查看，当然您必须致电完成处理3R？？
