在Cocoa中使用Spotlight [英] Using Spotlight in Cocoa

问题描述

我可以使用Cocoa中的Spotlight API（它们存在，对吗？）来确定Spotlight（在右上角）是否匹配给定的filePath和给定的字符串？

Can I use the Spotlight APIs (they exist, right?) in Cocoa to determine if Spotlight (in the upper-right corner) would match a given filePath with a given string?

换句话说，给定一个filePath（如/Users/enchilada/Desktop/MapOfUSA.pdf）和一个字符串（如Virginia），我如何知道Spotlight会在Virginia将在右上角Spotlight搜索中键入？ （你可以想象，在所示的例子中，它可能匹配，因为美国的PDF地图可能包含Virgina。）

In other words, given a filePath such as "/Users/enchilada/Desktop/MapOfUSA.pdf", and a string such as "Virginia", how would I tell if Spotlight would show this file when "Virginia" would have been typed in the upper-right Spotlight search? (As you can imagine, in the example shown, it would probably be matched, because a PDF map of the USA probably contains Virgina.)

如果可能，一个简单的代码

If possible, a simple code piece to do this would be appreciated.

推荐答案

您可以使用 NSMetadataQuery 类或其基础CFType MDQuery 。 O'Reilly发布了一个示例。
