objective-c - Firebase FCM 实例 ID 为零(在真实设备上运行快速启动应用程序)

Question

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

重现步骤:

1. pod try Firebase，然后运行 ​​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) 上运行应用
4. 接受请求允许发送通知的对话框
5. 点击按钮
6. 实例 ID 标记为nil

我的 Mac 有适当的证书来开发和部署应用程序:

1. 我同时拥有 iOS 分发和 iOS 开发配置配置文件，使用“自动”设置选择。
2. 我安装了 iOS 分发证书和 iOS 开发证书，并使用“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 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)"

这是完整的控制台输出:

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Capabilities
下启用 Push Notifications
• 避免调用 unregisterForRemoteNotifications。此调用后，您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。我认为他们的方法调配存在错误。
• 在 didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 方法中调用 [[FIRMessaging messaging] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeUnknown]
