Swift 3-将包含内容的文件夹从主捆绑包复制到文档目录 [英] Swift 3 - Copy Folder w/ contents from Main Bundle to Documents Directory

问题描述

我的主捆绑包中有一些文件夹，其中有文件，我想在应用程序首次启动时将其复制/剪切到文档目录"中，以便从那里访问它们.我已经看过示例，但是它们全都在Obj-C中，并且我正在使用Swift3.如何做到这一点?

I have folders with files inside them in my main bundle, and I want to copy/cut them to the Documents Directory at first launch of the application to access them from there. I've seen examples but they're all in Obj-C and I'm using Swift 3. How can I do this?

推荐答案

我设法使用2个函数来做到这一点:

I managed to do it using 2 functions:

func copyFolders() {
    let filemgr = FileManager.default
    filemgr.delegate = self
    let dirPaths = filemgr.urls(for: .documentDirectory, in: .userDomainMask)
    let docsURL = dirPaths[0]

    let folderPath = Bundle.main.resourceURL!.appendingPathComponent("Test").path
    let docsFolder = docsURL.appendingPathComponent("Test").path
    copyFiles(pathFromBundle: folderPath, pathDestDocs: docsFolder)
}

func copyFiles(pathFromBundle : String, pathDestDocs: String) {
    let fileManagerIs = FileManager.default
    fileManagerIs.delegate = self

    do {
        let filelist = try fileManagerIs.contentsOfDirectory(atPath: pathFromBundle)
        try? fileManagerIs.copyItem(atPath: pathFromBundle, toPath: pathDestDocs)

        for filename in filelist {
            try? fileManagerIs.copyItem(atPath: "\(pathFromBundle)/\(filename)", toPath: "\(pathDestDocs)/\(filename)")
        }
    } catch {
        print("\nError\n")
    }
}
