swift - 从swift设置查找器标签？

Question

我可以使用以下代码在 swift 中获取 finder 标签:

if let tagArray = try url.resourceValues(forKeys:[.tagNamesKey]).tagNames {
    ...
}

但是设置会报错:

var values = URLResourceValues()
values.tagNames = finderTags

给出错误:

Compile Swift Module 'tagsync' (1 sources)
main.swift:104:20: error: cannot assign to property: 'tagNames' is a get-only property
                    values.tagNames = finderTags
                    ~~~~~~~~~~~~~~~ ^

如何在 swift 中编写标签？

Answer 1

您可以使用 NSURL(而非 URL)轻松编写 Finder 标签:

let myPath = "any POSIX path; spaces ok"  
var myFinderTags = ["a", "b", "c"]  
try NSURL(fileURLWithPath: myPath).setResourceValues([.tagNamesKey: myFinderTags])
