在 Swift 3.0 中创建目录 [英] Create Directory in Swift 3.0

问题描述

我是 9 年级的新生，学习 swift，正在创建一个学校项目.

I am a new student in 9th grade learning swift, creating a school project .

我正在尝试创建一个目录，我想在其中将扫描的文件保存为 pdf 格式.

I am trying to create a directory where I want to save a scanned file into pdf format.

在创建目录时出现以下错误.

While creating directory I am getting error below.

错误 1:

不能在属性初始值设定项中使用实例成员filemgr"；属性初始值设定项在 'self' 可用之前运行.

Cannot use instance member 'filemgr' within property initializer; property initializers run before 'self' is available.

错误 2:

预期声明

代码:

let filemgr = FileManager.default


let dirPaths = filemgr.urls(for: .documentDirectory, in: .userDomainMask)

let docsURL = dirPaths[0]

let newDir = docsURL.appendingPathComponent("data").path

do{
    try filemgr.createDirectory(atPath: newDir,withIntermediateDirectories: true, attributes: nil)
} catch {
    print("Error: (error.localizedDescription)")
}

请帮助我解决这个问题.

Please assist me in resolving this issue.

谢谢.

推荐答案

请使用此代码:

Swift 5.0、Swift 4.0 和Swift 3.0

let DocumentDirectory = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0])
let DirPath = DocumentDirectory.appendingPathComponent("FOLDER_NAME")
do
{
    try FileManager.default.createDirectory(atPath: DirPath!.path, withIntermediateDirectories: true, attributes: nil)
}
catch let error as NSError
{
    print("Unable to create directory (error.debugDescription)")
}
print("Dir Path = (DirPath!)")
