在Swift中使用NSFileManager和createDirectoryAtPath [英] Using NSFileManager and createDirectoryAtPath in Swift

问题描述

我正在尝试创建一个新文件夹，但是我不知道如何正确使用createDirectoryAtPath.

I'm trying to create a new folder, but I can't figure out how to use createDirectoryAtPath correctly.

根据文档，这是正确的语法:

According to the documentation, this is the correct syntax:

NSFileManager.createDirectoryAtPath(_:withIntermediateDirectories:attributes:error:)

我尝试过:

let destinationFolder: String = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
let deliverablePath: NSURL = NSURL.fileURLWithPath("\(destinationFolder)/\(arrayOfProjectIDs[index])")!
NSFileManager.createDirectoryAtPath(deliverablePath, withIntermediateDirectories: false, attributes: nil, error: nil)

但这给了我错误

通话中额外的参数"withIntermediateDirectories"

Extra argument 'withIntermediateDirectories' in call

我也尝试了很多变体，删除了参数等等，但是我不能让它没有错误地运行.有什么想法吗?

I've also tried a lot of variations, removing parameters and so on, but I can't get it to run without an error. Any ideas?

推荐答案

您忘记添加defaultManager()并将NSURL转换为String.

You forgot to add defaultManager() and to convert the NSURL to String.

您可以尝试更换

NSFileManager.createDirectoryAtPath(deliverablePath, withIntermediateDirectories: false, attributes: nil, error: nil)

与此(将您的NSURL转换为字符串)

with this (converting your NSURL to String)

var deliverablePathString = deliverablePath.absoluteString

NSFileManager.defaultManager().createDirectoryAtPath(deliverablePathString, withIntermediateDirectories: false, attributes: nil, error: nil)
