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

问题描述

我是9年级学习的新学生，敏捷，创建了一个学校项目.

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，要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，我在下面收到错误消息.

While creating directory I am getting error below.

错误1:

不能在属性初始化程序中使用实例成员'filemgr'；属性初始值设定项在自我"可用之前运行.

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

错误2:

预期的声明

Expected declaration

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)")
}

请协助我解决此问题.

谢谢.

推荐答案

请使用以下代码:

Swift 4.0 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!)")
