ios – Firebase(FCM)无法获取APNS令牌错误Domain = com.firebase.iid代码= 1001

我正在尝试使用FCM通知.
但是< FIRInstanceID / WARNING>无法获取APNS令牌错误Domain = com.firebase.iid代码= 1001“(null)”发生,所以我无法获得通知.
有什么问题？

在控制台,
无法获取APNS令牌错误Domain = com.firebase.iid代码= 1001“(null)”

以下是我的App Applegate代码

    }

        // If your application supports background execution,this method is called instead of applicationWillTerminate: when the user quits.

        FIRMessaging.messaging().disconnect()
        print("disconnected from FCM.")
    }

    func applicationWillEnterForeground(application: UIApplication) {
        // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
    }

    func applicationDidBecomeActive(application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was prevIoUsly in the background,optionally refresh the user interface.

        self.saveContext()

>如果我通过使用软件包ID发送通知,我可以从Firebase控制台获取通知.但是如果我们的服务器通过令牌将通知发送到特定设备,我无法得到.
