Firebase FCM 实例 ID 为零（运行真实设备上的快速启动应用程序）

Question

运行在我的 iPhone 上安装 FCM 演示应用程序不起作用 - Firebase ID 是 nil。

重现步骤：

pod try Firebase 和运行 10: quickstart-ios/messaging/FCM.xcodeproj
将我的 GoogleService-Info.plist 文件复制到项目中
运行应用 iPhone 5 秒 (iOS 9.3.2)
接受请求发送通知权限的对话框
点击按钮
实例 ID 令牌是 nil

我的 Mac 有适当的证书来开发和部署应用程序：

我有 iOS 发行版和 iOS 开发配置配置文件，使用 'automatic' 设置选择。
我同时安装了 iOS 发行版和 iOS 开发证书，并使用 'automatic: iPhone developer' 选项
我安装了 'Production' SSL 证书：“Apple Push Notification 服务 SSL（沙盒和生产）"

我在日志中看到很多噪音，但最重要的错误是这个：

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

这里是完整的控制台输出：

我只是运行模拟器上的相同代码（iPhone 5，iOS 9.3），我很顺利地得到了一个令牌。

不过我确实看到了很多相同的警告...

Answer 2

问题是由于我使用的是 'Production' SSL 证书，而不是 'Development' 证书。安装似乎可以解决问题。

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。本机 APN 可能是这种情况，但它不适用于 Firebase。

Answer 3

如果你遇到过运行这个命令：

[[UIApplication sharedApplication] unregisterForRemoteNotifications],

您的应用将无法注册远程通知。

您需要卸载该应用程序才能使其再次运行...

Answer 4

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！

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

Answer 5

对我来说，如果发生在我从 Firebase 获取值之前不使用 FIRAuth 的情况下。

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 6

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 Capabilities

Push Notifications

避免调用 unregisterForRemoteNotifications。此调用后，您将无法再注册设备以推送通知。
在您的 info.plist 文件中将 FirebaseAppDelegateProxyEnabled 设置为 NO。我认为他们的方法 swizzling 存在错误。
在方法didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken中调用[[FIRMessaging messaging] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeUnknown]

在 Firebase 的 Cloud Messaging 选项卡中添加您的 APNS.p12
