在Swift中使用NSFileManager和createDirectoryAtPath

Question

我正在尝试创建一个新文件夹,但我无法弄清楚如何正确使用createDirectoryAtPath.

根据文档,这是正确的语法:

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

我试过这个:

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

调用中的额外参数'withIntermediateDirectories'

我也尝试过很多变化,删除参数等等,但我无法在没有错误的情况下运行它.有任何想法吗？

Answer 1

Swift 2.0方式:

do {
    var deliverablePathString = "/tmp/asdf"
    try NSFileManager.defaultManager().createDirectoryAtPath(deliverablePathString, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
    NSLog("\(error.localizedDescription)")
}

Answer 2

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

你可以尝试更换

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

用此(将NSURL转换为String)

var deliverablePathString = deliverablePath.absoluteString

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

希望这可以帮助
