ios - Firebase Cloud Messaging 通知未显示在 iOS 设备上(前台和后台)

Question

我正在使用 FCM 为我的 iOS 应用创建和发送推送通知。

开发环境:

• Xcode 11.3

• 运行 iOS 13.3 的 iPhone X

• swift 5.2

Pod 版本:

• Firebase 6.14.0
• FirebaseMessaging 4.1.10
• FirebaseInstanceID 4.2.8

问题:

在遇到问题之前，我已将我的应用程序设置为能够在应用程序处于后台和前台时接收通知。我对自己提交了代码感到非常满意。在此之后，我无法在前台或后台接收通知。无论使用通知是从 Cloud Messaging 仪表板还是 POSTMAN 发送的，我都会收到成功的响应，但通知从未出现。

起初我以为我可能已经达到了通知配额，但现在已经是 2 天了。

为了排除故障我已经尝试过:

1. 卸载并重新安装应用(刷新设备 token )
2. 将 UIApplication.shared.registerForRemoteNotifications() 移动到 FirebaseApp.configure() 之前
3. 下载新的 GoogleService-Info.plist 并替换现有的
4. 检查包 ID 等是否全部匹配
5. 将 firebase pod 更新到最新版本(如果有帮助，FirebaseMessaging 是 4.1.9)
6. 设置 Messaging.messaging().shouldEstablishDirectChannel = true
7. 删除并重新添加所需的功能
8. 将 FirebaseAppDelegateProxyEnabled 设置为 YES 和 NO
9. 设置shouldEstablishDirectChannel = true
10. 设置useMessagingDelegateForDirectChannel = true
11. 将一些逻辑从 didFinishLaunchingWithOptions() 移到了 applicationDidBecomeActive()

代码:

注意:这是最初为我工作的未更改代码。

我能够通过移动来解决问题

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)

从 PushNotificationManager 到 AppDelegate。希望这对其他人有帮助!
