问题描述
1。我在firebase控制台中创建了项目。
2。在Apple帐户上创建用于推送通知的证书
3。添加了GoogleService-info.plist，作为BundleResource
这是我在AppDelegate中的代码
[Register("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate,IUNUserNotificationCenterDelegate,IMessagingDelegate

// This method is invoked when the application has loaded and is ready to run. In this

// visible.

Console.WriteLine(userInfo);
completionHandler();
}
}
坚持这一周。我不知道接下来要做什么。有什么建议吗？我从应用程序复制了fcmToken，然后将其粘贴到Firebase控制台中以获取测试消息。
