Ios 如何使firebase推送通知工作

我花了大约2天的时间浏览Firebase文档，询问问题，查看其他人，并关注youtube/medium教程等

但我还没有弄清楚如何从firebase云消息发送通知消息。我已经设置了苹果推送服务，并将认证密钥输入firebase，并在我的应用程序中编写了代码

有人能让我知道我需要做什么才能让它工作吗？我错过了什么？

以下是我的

didRegisterForRemoteNotificationsWithDeviceToken

方法：

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Messaging.messaging().apnsToken = deviceToken
    let tokenParts = deviceToken.map { data in String(format: "%02.2hhx", data) }
    let token = tokenParts.joined()
    print("Device Token: \(token)")

}

更新：

显然，代码正在运行，因为我有两行代码将令牌保存到firebase，并成功地保存了令牌

假设您在firebase控制台中正确配置了APNS Auth密钥，并且考虑到您提供的appDelegate实现，我看到缺少的唯一一段代码是创建的FIRInstanceId

根据Firebase文档：

实例ID为每个应用程序实例提供唯一标识符，并提供一个机制>，用于验证和授权操作（例如，发送FCM消息）

生成InstanceID后，库会定期向Firebase>后端发送有关应用程序及其运行设备的信息>

及

要发送或接收消息，应用程序必须从>FIRInstanceID获取注册令牌。此令牌授权应用服务器向app>实例发送消息

在应用程序中注册远程通知的位置之前，请在应用程序之前添加此项。registerforremotentifications（）

让我知道这是否有帮助：）

我以前遇到过类似的问题，我解决的方法是检查auth key和fire项目以及Xcode中的

捆绑ID是否相同

此外，要确保应用程序代理代码正确，只需使用：

您是否使用DeviceToken实现了DidRegisterForRemotionTifications
DidRegisterForRemotionTifications
？你能提供这段代码吗？检查更新…别忘了检查生产/开发模式我在哪里找到这个@firebase的Vyacheslavcheck证书和管理面板
InstanceID.instanceID().instanceID { (result, error) in
    if let error = error {
        print("Error fetching remote instange ID: \(error)")
    } else if let result = result {
        print("Remote instance ID token: \(result.token)")
    }
}
