Xamarin iOS-Firebase Analytics不可用 [英] Xamarin iOS - Firebase Analytics is not available

问题描述

我已经从以下链接下载了示例项目和库: Xamarin Firebase 但配置2天后，启动应用程序时出现此错误:

I have download the example project and library from this link: Xamarin Firebase but after 2 days of configuration i get this error when i launch the app:

[Firebase/Core] [I-COR000022] Firebase Analytics不可用.

[Firebase/Core][I-COR000022] Firebase Analytics is not available.

我没有找到与Xamarin iOS Firebase Analytics的此错误相关的文档，也找不到解决方案.

I did not find documentation related to this error for Xamarin iOS Firebase Analytics and can not find a solution.

我引用了示例项目的相同库，检查了 GoogleService-Info.plist 并将其作为文档插入项目中，称为App.Configure ();.

I have reference the same library of the example project, checked the GoogleService-Info.plist and insert it in the project as documentation, called the App.Configure ();.

无事可做，有人有什么主意吗?

Nothing to do, does anyone have any idea?

推荐答案

已解决！

Firebase Analytics需要3个引用才能工作:

Firebase Analytics requires 3 references to work:

1. .Core
2. .Analytics
3. .IstanceID

仅遵循文档中的代码，在启动时仅加载项目 .Core ，而跳过其他两个，则将导致错误.

Following only the code in the documentation the project at start-up load only .Core skipping the other two, this causes the error.

要变通解决此问题，我添加了 AppDelegate :

To work around this problem, I added in AppDelegate:

using Firebase.Analytics;
using Firebase.InstanceID;

和App.Configure ();之前，我添加了以下两行以强制应用程序加载两个程序集:

and before of App.Configure (); i have add this two line to force the app to load the two assemblies:

Firebase.Analytics.Loader loader1 = new Firebase.Analytics.Loader();
Firebase.InstanceID.Loader loader2 = new Firebase.InstanceID.Loader();

当然，如果稍后使用这两个程序集实现其他指令，则将不需要这两个指令.

Of course, if you implement other instructions later using these two assemblies, you will not need these two instructions.
