【问题描述】：

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。

这是说我的注册令牌没有注册。在查看了 firebase 文档后，我看到了：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而被取消注册，包括：

客户端应用从 FCM 中取消注册 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，则会发生这种情况。） 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，请移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）

【问题讨论】：

直接通道已被弃用，但在 Firebase 6 中仍然有效。它与您的问题无关。

【参考方案1】：

设备令牌会随着时间而改变，因此如果您存储设备令牌，则需要确保每次启动应用时您都refresh the token。
