is deprecated：FCM 直接通道已被弃用，请使用 APNs 进行下游消息处理

Question

我在为 IOS 构建时收到这些消息，它成功但 IOS 通知不起作用，我收到 FCM 未注册的消息/注册令牌，所以我认为这篇文章可能与此错误有关。

它说我的注册令牌未注册。在查看 firebase 文档后，我看到：https : //firebase.google.com/docs/cloud-messaging/send-message#admin_sdk_error_reference

消息/注册令牌未注册：

提供的注册令牌未注册。以前有效的注册令牌可能因多种原因被取消注册，包括：

客户端应用程序从 FCM 自行取消注册客户端应用程序已自动取消注册。（如果用户卸载应用程序，或者在 iOS 上，如果 APNS 反馈服务报告 APNS 令牌无效，就会发生这种情况。）注册令牌已过期。（例如，Google 可能决定刷新注册令牌，或者 iOS 设备的 APNS 令牌可能已过期。）客户端应用程序已更新，但新版本未配置为接收消息。对于所有这些情况，请删除此注册令牌并停止使用它来发送消息。

但我觉得我已经满足了所有要求（APNS 已经配置并添加到 Firebase 控制台中）

设备令牌可能会随着时间的推移而发生变化，因此，如果您存储设备令牌，则需要确保每次启动应用程序时刷新令牌。
