swift - 在 iOS 应用程序中查找文件

Question

我知道我的文件在 data/Containers/Bundle/Application 中

我想列出来试试

let documentsUrl =  FileManager.default.urls(for: .applicationDirectory, in: .allDomainsMask).first!

do {
    // Get the directory contents urls (including subfolders urls)
    let directoryContents = try FileManager.default.contentsOfDirectory(at: documentsUrl, includingPropertiesForKeys: nil)
    print(directoryContents)

} catch {
    print(error)
}

但是我收到消息:

Error Domain=NSCocoaErrorDomain Code=260 "The file “Applications” couldn’t be opened because there is no such file."

那么如何按捆绑列出文件？

Answer 1

您可以获得您的包 url Bundle.main.bundleURL，获取其父目录并列出其内容:

extension URL {
    var parentDirectory: URL? {
        return (try? resourceValues(forKeys: [.parentDirectoryURLKey]))?.parentDirectory
    }
}

if let bundleDirectory = Bundle.main.bundleURL.parentDirectory {
    print(bundleDirectory)
    do {
        let directoryContents = try FileManager.default.contentsOfDirectory(at: bundleDirectory, includingPropertiesForKeys: nil)
        print(directoryContents)
    } catch {
        print(error)
    }
}
