推送通知不起作用 - Firebase 云消息传递

Question

我检查了我的代码，我不确定我发送消息时是否遗漏了任何东西，抛出了它发送的 Firebase，但在我的模拟器上它没有显示通知。我正在使用 apnsKey 我真的不知道出了什么问题无论如何要解决问题或发现活在这个问题上已经有一段时间了

从 Xcode 稳定版 11.3.* 开始，要在 iOS 上测试推送通知，您需要一台真实设备。无法在模拟器上进行测试。不过，如果手边没有真机，可以下载 Xcode 11.4 beta。

您可以在 Xcode 11.4 的官方 release notes 的 Simulator -> New Features 部分下找到以下内容

模拟器支持模拟远程推送通知，包括 背景内容获取通知。在模拟器中，拖放一个 APNs 文件到目标模拟器。该文件必须是 JSON 文件 有效的 Apple 推送通知服务负载，包括“aps” 钥匙。它还必须包含一个顶级“模拟器目标包”，其中包含 与目标应用程序包标识符匹配的字符串值。
