我在应用程序中启用了推送通知。

​

​

在Firebase，我注册了我的Auth密钥

​

运行我的应用程序在设备上运行，我收到一个防火墙令牌。

​

但是当我从Firebase运行一条测试消息时，我不会在电话或控制台上收到通知。

我也有同样的问题，只是通过禁用方法swizzling来解决它。下面是关于如何做到这一点的链接：https://firebase.google.com/docs/cloud-messaging/ios/client

基本上你需要这样做：

不喜欢使用swizzling的

开发人员可以通过在应用程序的Info.plist文件中添加标志FirebaseAppDelegateProxyEnabled并将其设置为NO (布尔值)来禁用它。

然后：

func application(application: UIApplication,
             didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
             Messaging.messaging().apnsToken = deviceToken
}
