为什么我在控制台ios10.2上接收消息时没有收到横幅和后台模式推送通知

以下是我的设置：

我无法在后台获取横幅和通知，尽管我在控制台中获取消息，例如-voidapplicationReceivedRemoteMessage:firmMessageingRemoteMessage*remoteMessage已触发

也没有声音，所有配置文件都已完成，以防万一。

您需要在if语句之前调用[FIRApp configure]

好的，解决了。您需要在apple developer站点中设置应用程序ID，并在开发和分发时启用推送通知。捆绑包id必须与Xcode上的捆绑包id匹配。之后，您需要为该应用程序id创建一个配置文件，并将其安装到mac中。最后但并非最不重要的一点是，您需要将密钥链访问生成的p12文件放入Firebase控制台。在firebase控制台中，概览旁边有一个灰色齿轮按钮。您选择该选项，然后单击云消息选项卡，然后在扩展推送通知证书并导出p12文件时上载在keychain access中生成的p12证书文件。您需要输入密码并将其上载到firebase。

没有人对此有答案……我的死胡同丢失了，我已经搜索了所有相关主题，在ios10.2中，我没有收到应用程序在后台或关闭时的通知，也没有收到应用程序在前台时的横幅…我所能做的就是在控制台中显示消息时显示一个警报框…有人对此有任何想法…请帮助您检查了吗，来自ApplicationIDBecomeActive connectToFcm的成功响应？是的用户3585096，我正在连接到FCM，我得到了一个令牌…似乎内部通知机制根本不起作用…我现在也有同样的问题，如果我发现了，我会让你知道，visa也会告诉你，谢谢你。我以为它根本不起作用，但后来注意到控制台正在打印它：恐怕不是因为我在didFinishLaunchingWithOptions开始时移动了[FIRApp configure]，但仍然是一样的…实际上只是在我的iPhone 5,2上测试了firebase消息示例，它在那里也做了同样的事情…在控制台上没有收到横幅，没有背景通知。搞笑的是，在解决问题后，在开发模式下，当我发布应用程序的更新时，通知停止在那里工作……另一个噩梦开始了！三周前发布了一个后续问题，因为推送通知现在只能在开发模式下工作，而不能在生产模式下工作。。。。。
