在APNs Cert更改后，推送通知不会从FCM发送
在我的某个证书过期之前，我没有将从FCM发送推送通知到我的iOS应用程序的问题。更改后，FCM不再提供消息。我读过这篇文章（https://firebase.googleblog.com/2017/01/debugging-firebase-cloud-messaging-on.html），这是迄今为止我所经历过的验证步骤，但现在我正在敲打我的脑袋......
- 注释掉任何connectToFCM功能
- 已下载Pusher并成功使用APNs证书向设备发送通知
- 成功完成了对FCM的卷曲调用（下面的回复）
- {＆＃34; multicast_id＆＃34;：7774794018682407760，＆＃34;成功＆＃34;：1，＆＃34;失效＆＃34;：0，＆＃34; canonical_ids＆＃34;：0，＆＃ 34;结果＆＃34;：[{＆＃34; MESSAGE_ID＆＃34;：＆＃34; 0：1493321644068397％b76e8527b76e8527＆＃34;}]}
- 尝试重新创建开发和生产证书
- 尝试使用和不使用密码从钥匙串导出它们
任何人都有过这种令人沮丧的事情的经验，并就如何继续提出建议？
同样值得注意的是，我无法删除APNs证书，我看到了选项，但它显示为灰色，我无法选择它。

您可以创建一个APNs密钥，并将其用于所有应用程序，而不是使用APNS证书进行推送通知。
的APN 使用Apple推送通知服务来处理通知请求。一键用于所有应用。有关更多信息，请参阅本地和远程通知编程指南。
即使FCM支持这一点。现在，您可以避免为每个应用程序ID创建APNS证书。

这有助于理解流程。

您已经测试过APN发送给应用程序。所以证书很好。
从您关联的the blog，通过拨打电话获得成功回复意味着FCM正在接收该消息。这并不意味着消息正在传递给APN。
使用Firebase通知面板直接发送消息，以查看FCM是否正在与APN进行通信。
如果可行，那么您的邮件格式就会出现问题。
如果它不起作用。
确保：
-
邮件优先级设置为
high，因此会立即发送。 -
＆＃34; content_available＆＃34;：true
-
卸载并重新安装应用
-
检查您的服务器代码。

请在YourProjectSetting =＆gt; cloudmessaging =＆gt;中更新您的APNs证书（制作和开发）。 iOS应用配置。 Firebase Cloud Messaging可以使用APNs身份验证密钥或APNs证书与APN连接
注意：确认您的项目凭据（SenderID，旧服务器密钥，服务器密钥）。
HTTP POST请求：用于发送通知。
