代码示例：

/// home沙盒主目录路径
let pathHome = NSHomeDirectory();
print("home沙盒主目录路径：\(pathHome)")

/// temp临时目录
let pathTemp = NSTemporaryDirectory();
print("temp临时目录：\(pathTemp)")

/// document文档目录
let array = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory,NSSearchPathDomainMask.UserDomainMask,true);
let pathDecument = array.first!;
print("document文档目录：\(pathDecument)")

/// cache缓存目录
let arrayCache = NSSearchPathForDirectoriesInDomains(.CachesDirectory,.UserDomainMask,true);
let pathCache = arrayCache.first!;
print("cache缓存目录：\(pathCache)")

/// library目录
let arrayLibrary = NSSearchPathForDirectoriesInDomains(.LibraryDirectory,true);
let pathLibrary = arrayLibrary.first!;
print("library目录：\(pathLibrary)")

/// home主目录自定义文件路径
var pathHomeWithName = NSHomeDirectory() as NSString
pathHomeWithName = pathHomeWithName.stringByAppendingPathComponent("devZhang")
print("home主目录自定义文件路径：\(pathHomeWithName)")

/// temp临时目录自定义文件路径
var pathTempWithName = NSTemporaryDirectory() as NSString
pathTempWithName = pathTempWithName.stringByAppendingPathComponent("devZhang")
print("temp临时目录自定义文件路径：\(pathTempWithName)")

/// document文档目录自定义文件路径

print("document文档目录自定义文件路径：\(pathDocumentWithName)")

/// cache缓存目录自定义文件路径
var pathCacheWithName = pathCache as NSString
