推送通知正在发送但未收到 iOS - 云功能

Question

我正在尝试向我用于测试的 iPhone 6s 发送推送通知。我已经阅读了 Firebase 文档，但我似乎无法收到通知到达手机。当我尝试使用注册后获得的 FCM 令牌发送测试通知时，它在 firebase 控制台上被归类为“已发送”，而不是“已接收”。

该应用的最低软件版本为 iOS 13，因此我没有为通知服务添加已弃用的功能。

我试过了：

• 在 xcode 中禁用和重新启用推送通知和后台任务功能
• 使用功能创建了新证书和配置文件
• 从手机中卸载应用并重新安装
• 在 Info.plist 文件中将 FirebaseAppDelegateProxyEnabled 设置为 NO 和 YES
• 编写并运行云函数，用于发送根据 Firebase 控制台运行为“ok”的通知
• 清理构建文件夹
• 使用注册时返回的所有令牌

任何帮助将不胜感激， 在此先感谢:)

终于！我试图通过从头开始并开始创建另一个应用程序来解决这个问题。在该过程进行到一半时，我发现我没有将 .p8 文件上传到 Firebase 以用于我试图获取通知的应用程序（我以为我有，但显然没有）。

如果您有同样的问题，请检查您的应用是否已在控制台上正确注册 Firebase 以进行云消息传递！
