快速递归列出文件夹中的所有文件 [英] listing all files in a folder recursively with swift

问题描述

我正在学习快速，想知道在目录中列出具有绝对路径的所有文件的最佳方法是什么，包括子文件夹(仅文件)中的文件

I'm learning swift and wondering what's the best way to list all files with absolute path in a directory including ones from subfolders(files only)

我尝试了以下操作，但似乎列出了所有内容名称，甚至没有完整路径的文件夹名称.

I tried with following, but it seems listing all contents names even folder names without full paths.

let paths = FileManager.default.subpaths(atPath: folderPath)
    for p in paths! {
       print p
    }
}

以及

让项目=尝试fm.contentsOfDirectory(atPath:folderPath)

搜索没有任何可行的方法.

googling didn't come out with any working methods.

这是针对macOS 10.14

感谢您的帮助！

推荐答案

FileManager 还有一种用于深度搜索的方法:

FileManager has also a method for a deep search: enumerator(at:includingPropertiesForKeys:options:errorHandler:)

要仅获取文件，您必须迭代枚举器并过滤文件

To get only the files you have to iterate the enumerator and filter the files

let url = URL(fileURLWithPath: "/path/to/directory")
var files = [URL]()
if let enumerator = FileManager.default.enumerator(at: url, includingPropertiesForKeys: [.isRegularFileKey], options: [.skipsHiddenFiles, .skipsPackageDescendants]) {
    for case let fileURL as URL in enumerator {
        do {
            let fileAttributes = try fileURL.resourceValues(forKeys:[.isRegularFileKey])
            if fileAttributes.isRegularFile! {
                files.append(fileURL)
            }
        } catch { print(error, fileURL) }
    }
    print(files)
}

强烈建议使用URL而不是字符串路径.

It's highly recommended to use URLs rather than string paths.
