在第一节中我们演示了资源规范工具的写法。在上一节中我们遇到了强制Sprite图片的命名规范的情况（不按照规范命名的Sprite加载不出来），这一节就来实现一个检测命名规范的工具。

TextureSetting

修改TextureSetting，增加检测指定文件夹路径内文件名的逻辑

public class TextureImportSetting : AssetPostprocessor
{
    private static FolderData _playerData;//Editor环境下的变量必须是静态的
    private void OnPreprocessTexture()
    {
        NamingConvention();

    }

            string pattern = @"^\d+_\d+$";
            if (!Regex.IsMatch(name, pattern))
            {
                if (_playerData == null)
                {
                    _playerData = new FolderData()
                    {
                        FolderPath = Path.PLAYER_PICTURE_FOLDER,
                        NameTip = "0_0"
                    };
                }

                Debug.LogError("当前导入资源命名不规范：" + name);
                NameMgrWindowData.Add(_playerData, assetPath);
                NameMgrWindow.ShowWnd();
            }

        }
    }
    private void SetTexturePara()
    {
        TextureImporter importer = assetImporter as TextureImporter;
        importer.textureType = TextureImporterType.Sprite;
        importer.mipmapEnabled = false;
    }
}

@"^\d+_\d+$"表示必须是“数字_数字”的格式，例如“2_7”、“12_18”。“^”和“$”代表定位开头和结尾，“\d”表示09，“\d+”表示09这些数字至少出现一次。“_”表示中间的字符必须是“_”。

EditorWindow.GetWindow<NameMgrWindow>()方法能够生成NameMgrWindow的实例。

NameMgrWindowData：用来缓存NameMgrWidow内需要显示的数据的类，里面有一个字典，key值是需要设置命名规范的文件夹信息类，value是一个列表，保存了当前命名不规范的图片资源的全路径。

FolderData：用来保存需要强制命名的文件夹路径，以及正确命名的提示
