Question

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

重现的步骤：

var dataset = {"nodes":[{"name":"Anglo American plc"},{"name":"Associated British Foods plc"},{"name":"Admiral Group plc"},{"name":"ARM Holdings plc"},{"name":"Aviva plc"},{"name":"BAE Systems plc"},{"name":"Barclays PLC"},{"name":"British American Tobacco p.l.c."},{"name":"The Berkeley Group Holdings plc"},{"name":"BHP Billiton plc"},{"name":"BP p.l.c."},{"name":"BT Group plc"},{"name":"Centrica plc"},{"name":"Compass Group PLC"},{"name":"Direct Line Insurance Group PLC"},{"name":"easyJet plc"},{"name":"International Consolidated Airlines Group, S.A."},{"name":"3i Group plc"},{"name":"Intertek Group plc"},{"name":"Lloyds Banking Group plc"},{"name":"Merlin Entertainments plc"},{"name":"Pearson plc"},{"name":"Reckitt Benckiser Group plc"},{"name":"Royal Dutch Shell plc"},{"name":"Rexam PLC"},{"name":"Rio Tinto plc"},{"name":"SABMiller plc"},{"name":"Schroders plc"},{"name":"Standard Life plc"},{"name":"SSE plc"},{"name":"Standard Chartered PLC"},{"name":"Tesco PLC"},{"name":"Whitbread PLC"}],"edges":[{"source":0,"target":29,"officers":["MEDORI, Rene"]},{"source":0,"target":30,"officers":["GROTE, Byron Elmer"]},{"source":0,"target":31,"officers":["GROTE, Byron Elmer"]},{"source":1,"target":13,"officers":["BASON, John George"]}]};，并运行pod try Firebase
将我的10: quickstart-ios/messaging/FCM.xcodeproj文件复制到项目中
在iPhone 5s（iOS 9.3.2）上运行该应用程序
接受请求发送通知权限的对话框
点击按钮
Instance Id令牌为 nil

我的Mac拥有适当的证书来开发和部署应用程序：

我同时拥有iOS发布和iOS开发配置配置文件，使用“自动”设置选择。
我安装了iOS发行版和iOS开发证书，使用“自动：iPhone开发者”选项进行代码签名
我安装了“Production”SSL证书：“Apple推送通知服务SSL（沙箱和生产）“

我在日志中看到很多噪音，但最重要的错误就是这个：

GoogleService-Info.plist

以下是完整的控制台输出：

Failed to fetch default token Error Domain=com.firebase.iid Code=0 "(null)"

Answer 1

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：

在应用的Push Notifications

Capabilities

避免致电unregisterForRemoteNotifications。拨打此电话后，您无法再注册设备以推送通知。
在info.plist文件中将FirebaseAppDelegateProxyEnabled设置为NO。我认为他们的方法有很多错误。
在方法[[FIRMessaging messaging] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeUnknown]

didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken

Answer 2

我刚刚在模拟器上运行了相同的代码（iPhone 5，iOS 9.3），我没有遇到任何麻烦。

我确实看到了很多相同的警告，但是......

Answer 3

除了在您的开发计算机上安装APNs SSL证书外，您还需要将它们上传到Firebase控制台！

https://console.firebase.google.com/project/your-project-name-here/settings/cloudmessaging

Answer 4

问题是由于我使用了“生产”SSL证书，而不是“开发”证书。安装它似乎解决了问题。

我错误地认为开发版和生产版都将由“Apple推送通知服务SSL（沙盒和生产）”证书处理。对于本机APN可能就是这种情况，但它对Firebase不起作用。

Answer 5

如果您碰巧运行此命令：

[[UIApplication sharedApplication] unregisterForRemoteNotifications],

您的应用无法注册远程通知。

registerusernotificationsettings not work after using unregisterForRemoteNotifications

您需要卸载该应用才能让它再次运行...

Answer 6

对我来说，如果我在从Firebase获取值之前没有使用FIRAuth，那就发生了。

FIRAuth.auth()?.signIn(withEmail: "test1@gmail.com", 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
        }
    })

})

请试一试。如果它不起作用，请告诉我。

Answer 7

在Cloud Messaging选项卡中的Firebase中添加APNS.p12

https://console.firebase.google.com/project/VBTechlabsApp(YOUR_APP_NAME)/settings/cloudmessaging

Firebase FCM实例ID为零（在真实设备上运行快速入门应用）
