来自 Amazon SNS 的 VoIP 推送

Question

我正在尝试从 Amazon SNS 发送 VoIP 推送，有一个 firebase 函数可以在收到 VoIP_token 时创建 ARN 并使 SNS 推送 VoIP 推送。现在我面临一个问题。

=> 推送来自 didReceiveIncomingPushWith 负载，但是在这个委托方法中，我正在尝试更新 firebase 值，正如您在代码中看到的那样，这也有效，android 在 5 分钟后发送推送来自已在 firebase 功能中配置的 SNS，但问题是有时推送有时不推送，在开发版本中它工作正常但是当我投入试飞时它经常工作

Answer 1

您使用 Xcode 11 和 iOS13 吗？ Apple 对 VoIP 推送通知进行了重大更改。使用 VoIP 时，您需要向 CallKit 报告 "incoming call"。

On iOS 13.0 and later, if you fail to report a call to CallKit, the system will terminate your app. Repeatedly failing to report calls may cause the system to stop delivering any more VoIP push notifications to your app. If you want to initiate a VoIP call without using CallKit, register for push notifications using the UserNotifications framework instead of PushKit.

Answer 2

我已经查看了您的代码，我认为您需要对 VOIP 进行一些说明。

当您收到 VOIP 推送时，您的应用最多激活 30 秒。

我注意到您在收到推入 iOS 设备时执行了一些繁重的操作。我认为这是您代码中的主要问题。

解决这个问题

降低 GPS 的精度级别。

删除或优化您的代码（只需将所需数据存储或更新到 firebase，避免无用的操作）

还有一件事，我想澄清一下推送有时来有时不来

如果您尝试向同一台设备发送多个 Push，那么一些跳过推送。
