获取文档文件夹中的文件列表 [英] Getting list of files in documents folder

问题描述

我的代码在文档文件夹中获取文件名有什么问题？

What is wrong with my code for getting the filenames in the document folder?

func listFilesFromDocumentsFolder() -> [NSString]?{
    var theError = NSErrorPointer()
    let dirs = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true) as? [String]
    if dirs != nil {
        let dir = dirs![0] as NSString
        let fileList = NSFileManager.defaultManager().contentsOfDirectoryAtPath(dir, error: theError) as [NSString]
        return fileList
    }else{
        return nil
    }
}

我以为我正确阅读了文档，我非常确定文档文件夹中的内容，但fileList没有显示任何内容？ dir显示文件夹的路径。

I thought I read the documents correctly and I am very sure about what is in the documents folder, but "fileList" does not show anything? "dir" shows the path to the folder.

推荐答案

这是一个适用于Swift 4 / Xcode 9.2的解决方案：

Here's a solution that will work with Swift 4/Xcode 9.2:

let fileManager = FileManager.default
let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
do {
    let fileURLs = try fileManager.contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil)
    // process files
} catch {
    print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
}
