Firebase FCM Instance ID is nil (running quickstart app on real device)

objective-ciphonexcodefirebase-cloud-messaging

提问by IanS

Running the FCM demo app on my iPhone doesn't work - The Firebase ID is nil.

在我的 iPhone 上运行 FCM 演示应用程序不起作用 - Firebase ID 为nil。

Steps to reproduce:

重现步骤：

  1. pod try Firebase, and run 10: quickstart-ios/messaging/FCM.xcodeproj
  2. Copy my GoogleService-Info.plistfile into the project
  3. Run the app on an iPhone 5s (iOS 9.3.2)
  4. Accept the dialog requesting permission to send notifications
  5. Click the buttons
  6. The Instance Id token is nil
  1. pod try Firebase，并运行 10: quickstart-ios/messaging/FCM.xcodeproj
  2. 将我的GoogleService-Info.plist文件复制到项目中
  3. 在 iPhone 5s (iOS 9.3.2) 上运行该应用程序
  4. 接受请求发送通知权限的对话框
  5. 单击按钮
  6. 实例 ID 令牌为零

My Mac has the appropriate certificates to develop and deploy apps:

我的 Mac 拥有相应的证书来开发和部署应用程序：

  1. I have both iOS distribution and iOS development provisioning profiles, chosen using the 'automatic' settings.
  2. I have both iOS distribution and iOS development certificates installed, code-signed using the 'automatic: iPhone developer' option
  3. I have the 'Production' SSL certificate installed: "Apple Push Notification service SSL (Sandbox & Production)"
  1. 我有 iOS 发行版和 iOS 开发配置文件，使用“自动”设置选择。
  2. 我安装了 iOS 发行版和 iOS 开发证书，使用“自动：iPhone 开发人员”选项进行了代码签名
  3. 我安装了“生产”SSL 证书：“Apple 推送通知服务 SSL（沙盒和生产）”

I see lots of noise in the logs, but the most significant error is this one:

我看到日志中有很多噪音，但最重要的错误是这个：

As well as installing the APNs SSL certificates on your dev machine, you also need to upload them to the Firebase Console!

除了在您的开发机器上安装 APNs SSL 证书外，您还需要将它们上传到 Firebase 控制台！

Try updating Firebase/Core to v3.4.4, it fixed unexpected errors for me. Otherwise the typical fixes are:

尝试将 Firebase/Core 更新到 v3.4.4，它为我修复了意外错误。否则，典型的修复是：

  • Enabling Push Notificationsunder the app's Capabilities
  • Avoid calling unregisterForRemoteNotifications. After this call, you can't register the device anymore to push notifications.
  • Setting FirebaseAppDelegateProxyEnabledto NOin your info.plist file. I think there are bugs with their method swizzling.
  • Calling [[FIRMessaging messaging] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeUnknown]in the method didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
  • Push Notifications在应用程序下启用Capabilities
  • 避免调用unregisterForRemoteNotifications。此调用后，您无法再注册设备以推送通知。
  • 在 info.plist 文件中设置FirebaseAppDelegateProxyEnabled为NO。我认为他们的方法存在错误。
  • [[FIRMessaging messaging] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeUnknown]在方法中调用didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken

I just ran the same code on the simulator (iPhone 5, iOS 9.3), and I get a token without any trouble.

我只是在模拟器（iPhone 5、iOS 9.3）上运行了相同的代码，并且毫无问题地获得了令牌。

I do see lots of the same warnings, though...

不过，我确实看到了很多相同的警告......

The issue was due to my use of the 'Production' SSL certificate, instead of the 'Development' one. Installing that seemed to fix things.

问题是由于我使用了“生产”SSL 证书，而不是“开发”证书。安装它似乎可以解决问题。

I had wrongly assumed that both development and production versions would be handled by the "Apple Push Notification service SSL (Sandbox & Production)" certificate. That may be the case for native APNs, but it doesn't work for Firebase.

我错误地认为开发和生产版本都将由“Apple Push Notification service SSL (Sandbox & Production)”证书处理。原生 APN 可能就是这种情况，但它不适用于 Firebase。

If you have ever happened to run this command:

如果你曾经碰巧运行过这个命令：

[[UIApplication sharedApplication] unregisterForRemoteNotifications],

your app will not be able to register for remote notifications.

您的应用将无法注册远程通知。

registerusernotificationsettings not work after using unregisterForRemoteNotifications

使用 unregisterForRemoteNotifications 后 registerusernotificationsettings 不起作用

You need to uninstall the app to get it working again...

您需要卸载该应用程序才能使其再次运行...

回答by Ng?c Nguy?n

For me, If happened when i do not use FIRAuth before get values from Firebase.

对我来说，如果在从 Firebase 获取值之前我不使用 FIRAuth 时发生了这种情况。

FIRAuth.auth()?.signIn(withEmail: "[email protected]", password: "123456", completion: { (user, error) in
if(error != nil){
    print(error)
    return
}


let ref = FIRDatabase.database().reference(fromURL: "https://firdemo-84b6b.firebaseio.com/").child("users")

ref.observe(.value, with: { (snapshot) in
    print(snapshot.key)
    print(snapshot.value)
    }, withCancel: { (error) in
        if(error != nil){
            print(error)
            return
        }
    })

})

Please try it. And let me know if it does not work.

请尝试一下。如果它不起作用，请告诉我。
