限制NSMetadataQuery的范围(Limit scope of NSMetadataQuery)

限制NSMetadataQuery的范围(Limit scope of NSMetadataQuery)

我试图限制NSMetadataQuery项的范围。 我知道有-setSearchScope：方法（参见文档 ），但它只允许我决定项目将搜索哪些目录。

如果我需要从作用域中排除一个或多个目录怎么办？

I was trying to restrict the scope of an NSMetadataQuery item. I know there's the -setSearchScope: method (see the docs), but it lets me only decide in which directories the item will search.

What if I need to exclude one or more directories from the scope?

最满意答案

不幸的是，我不相信这是可能的，因为kMDItemPath属性没有被Spotlight索引，因此在查询中不可用。

提交错误 。

Unfortunately, I don't believe this is possible, since the kMDItemPath attribute is not indexed by Spotlight, and is therefore not usable in a query.
