錯誤：使用了NSDocumentDirectory，NSUserDomainMask，

Question

未解決的標識符我有一行代碼：

var path: NSArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, true) 

Xcode中拋出一個編譯時錯誤：

use of unresolved identifier : NSDocumentDirectory, NSUserDomainMask 

我想不出什麼錯誤。

Answer 1

試試這樣說：

var path: NSArray= NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true) 

Answer 2

let documentsUrl = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first as NSURL 
if let documentsPath = documentsUrl.path { 
    println(documentsPath) 
} 

Answer 3

let paths = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask) 
let documentsURL = paths[0] as NSURL
