本文详细介绍了在iOS环境中使用NSFileManager获取不同NSSearchPathDirectory时返回的具体路径，并对比了使用不同NSSearchPathDomainMask的区别。

参考：

1. http://stackoverflow.com/questions/13983091/nsfilemanager-urlsfordirectory-or-urlfordirectory

2. http://blog.youkuaiyun.com/enuola/article/details/8076221

目的：

其实参考里已经介绍了获取沙盒路径方法，但是我很想知道的是用NSUserDomainMask时，使用不同NSSearchPathDirectory 我的iOS返回是什么？

Environment: Mount Lion ,Xcode 4.5.3 , cocos2d-iphone V2.0

那么NSSearchPathDomainMask不是NSUserDomainMask时能使用urlForDirectoryxxx方法吗？？iOS下有啥不同？?

NSSearchPathDomainMask	URLForSearch=NSLibraryDirectory	URLForSearch=NSApplicationDirectory	URLForSearch=NSDemoApplicationDirectory
NSLocalDomainMask = 2	file://localhost/Library/	file://localhost/Applications/	file://localhost/Applications/Demos
NSNetworkDomainMask = 4	file://localhost/Network/Library	file://localhost/Network/Applications	file://localhost/Network/Applications/Demos
NSSystemDomainMask = 8	file://localhost/System/Library/	file://localhost/Applications/	file://localhost/Applications/Demos
NSAllDomainsMask = 0x0ffff	同NSUserDomainMake返回值	同NSUserDomainMake返回值	同NSUserDomainMake返回值
