在 Firebase 中使用推送通知时在 Swift 3 中收到警告？

Question

我正在为我的演示应用程序使用推送通知服务。使用 Firebase，我可以将通知发送到设备。但是我的日志消息中出现了一些警告。我怎样才能删除它？还有一件事，我如何在 Swift 3.

中使用更新后的 Xcode 8 获取设备令牌

Appdelegate 代码：

    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]
    UIBarButtonItem.appearance().tintColor = UIColor.whiteColor()

Answer 1

首先在didFinishLaunchingWithOptions

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

然后在Appdelegate.M中添加这个方法Class

func tokenRefreshNotification(notification: NSNotification) {

  let refreshedToken = FIRInstanceID.instanceID().token()
  print("InstanceID token: \(refreshedToken)")
  print("InstanceID token: \(notification.Object)")


  connectToFcm()
}

然后检查是否调用了此方法 (tokenRefreshNotification)？

在这个方法中你得到令牌ID
