我想在Unity上测试firebase初始应用程序.我在MacOS和xcode项目文件夹中使用Unity构建了一个版本,我已经成功运行了pod命令.

pod安装

在此之后我打开了xcode项目,然后点击构建按钮.在此之前,我发现框架未找到错误.我修好了,现在我得到了

我已经将库补丁添加到库搜索路径中.我添加了一些截图作为附件.

我的列表包括名为"ID","名称"和"类别"的类.列表中有6个项目.

List<MyData> list = 
{
    {0, "John", "Police"}, 
    {1,"Michael", "Police"},
    {2,"Alice", "Police"}, 
    {3, "Ferdinand", "Thief"}, 
    {4, "Jocas", "Thief"}, 
    {5, "Connor", "Thief"}
};

我想用LINQ的'Category'列出每组有限的数量.

示例:我想为每个'Cateogory'列出2项.列出的应该是:

John Police

Michael Police

Ferdinand Thief

Jocas Thief
