iOS Swift GCM / FCM在后台接收通知

Question

关闭应用后，我无法进行通知。

我是从FCM / GCM（python服务器）发送的：

{
  "registration_ids": ["APA91bEDB9dVf-..."]
  "collapse_key": null,
  "content_available": true,
  "data": {
    "msg": "{\"model\":\"article\",\"data\":\"reload\"}"
  },
  "notification": {
    "body": "my body",
    "sound": "default",
    "title": "my title"
  },
  "priority": "high",
  "time_to_live": 3600
}

所以卷曲是这样的：

  

curl --header“授权：key = MYKEY”--header“Content-Type：   application / json“https://fcm.googleapis.com/fcm/send -d   '{“registration_ids”：[“APA91bEDB9dVf -...”]，“collapse_key”：   null，“content_available”：true，“notification”：{“body”：“my   body“，”sound“：”默认“，”标题“：”我的标题“}，”优先级“：   “high”，“time_to_live”：3600，“数据”：   { “msg” 中： “{\” 模型\ “：\” 文章\ “\ ”数据\“：\ ”重载\“}”}}“

终端的响应是：

  

{ “multicast_id”：6089491211057070352， “成功”：1， “失败”：0， “canonical_ids”：0 “结果”：[{ “MESSAGE_ID”： “0：1471474398816666％cc062fb9cc062fb9”}]}

iOS应用中的

Background Modes已开启且Remote notifications：

AppDelegate.swift ：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()

    FIRApp.configure()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil)

    return true
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
    let notification = UILocalNotification()
    notification.alertBody = "Test"
    notification.alertAction = "open"
    notification.fireDate = NSDate(timeIntervalSinceNow: 1)
    notification.soundName = UILocalNotificationDefaultSoundName
    notification.userInfo = ["UUID": 12312]

    UIApplication.sharedApplication().scheduleLocalNotification(notification)
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
}

但是当我发送该消息时仍然没有显示，但是当应用程序打开时，通知可以正常工作。

可能有什么问题？

{   “到”： “ID”，   “通知”：{
    “声音”：“默认”，     “头衔”： “TITLE”     “体”： “BODY”   }，   “优先”：“高” } 以此模式创建通知
