iOS开发之查找目录

NSArray *path1=NSSearchPathForDirectoriesInDomains(NSCachesDirectory,
NSUserDomainMask, YES);//数据所在缓存的绝对路径

NSArray
*path2=NSSearchPathForDirectoriesInDomains(NSDesktopDirectory,
NSUserDomainMask, YES);//数据所存桌面的绝对路径

NSArray
*path3=NSSearchPathForDirectoriesInDomains(NSCachesDirectory,
NSLocalDomainMask, YES);//数据所在缓存的相对路径

NSArray
*path4=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);//数据所在文件documents的绝对路径

NSArray
*path5=NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory,
NSUserDomainMask, YES);//数据所在文件Library/Documentation的绝对路径

NSArray
*path6=NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,
NSUserDomainMask, YES);//数据所在文件Library的绝对路径

NSArray
*path7=NSSearchPathForDirectoriesInDomains(NSAllLibrariesDirectory,
NSUserDomainMask, YES);//数据所在文件Library的绝对路径

NSString
*destPath = NSHomeDirectory();

打印的结果:

path1=(

"/Users/yinsuke/Library/Application
Support/iPhone Simulator/6.0/Applications/FB3B8EAF-63D9-4CFE-878C-2692093CC763/Library/Caches"

得出的结论：

NSSearchPathForDirectoriesInDomains（“想要查找的目录”，“想要从哪个路径区域保护区查找”）

查找的区域：

typedef NS_OPTIONS(NSUInteger, NSSearchPathDomainMask) {

NSUserDomainMask
= 1, //
用户的主目录

NSLocalDomainMask
= 2, //
当前机器的本地目录

NSNetworkDomainMask
= 4, //
在网络中公开可用的位置

NSSystemDomainMask
= 8, //
被苹果系统提供的，不可更改的位置 (/System)

NSAllDomainsMask
= 0x0ffff // 上述所有及未来的位置

};

想要查找的目录：

NSApplicationDirectory = 1, //
到applications (Applications)目录下

NSDemoApplicationDirectory, //
到Applications/Demos目录下

NSDeveloperApplicationDirectory, //
到Developer/Applications目录下.

NSAdminApplicationDirectory, //
到Applications/Utilities目录下

NSLibraryDirectory, //
到Library目录下

NSDeveloperDirectory, //
到Developer目录下.

NSUserDirectory, //
到用户的主目录下

NSDocumentationDirectory, //
到documentation (Documentation)的目录下

NSDocumentDirectory, //
到documents (Documents)目录下

NSCoreServiceDirectory, //
CoreServices目录的位置 (System/Library/CoreServices)

NSAutosavedInformationDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 11, //
自动保存的文档位置 (Documents/Autosaved)

NSDesktopDirectory
= 12, //
本地用户的桌面

NSCachesDirectory
= 13, //
本地缓冲区目录(Library/Caches)

NSApplicationSupportDirectory
= 14, //
本地应用支持文件目录 (plug-ins, etc) (Library/Application Support)

NSDownloadsDirectory
NS_ENUM_AVAILABLE(10_5, 2_0) = 15, //
本地下载downloads目录

NSInputMethodsDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 16, //
输入方法目录 (Library/Input Methods)

NSMoviesDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 17, //
电影目录 (~/Movies)

NSMusicDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 18, //
音乐目录 (~/Music)

NSPicturesDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 19, //
图片目录 (~/Pictures)

NSPrinterDescriptionDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 20, //
PPDs目录 (Library/Printers/PPDs)

NSSharedPublicDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 21, //
本地用户分享目录 (~/Public)

NSPreferencePanesDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 22, //
PreferencePanes目录的位置使用系统的偏好设置 (Library/PreferencePanes)

NSApplicationScriptsDirectory
NS_ENUM_AVAILABLE(10_8, NA) = 23, //
本地用户 scripts 文件夹，对于所需的应用(~/Library/Application Scripts/code-signing-id)

NSItemReplacementDirectory
NS_ENUM_AVAILABLE(10_6, 4_0) = 99, //
For use with NSFileManager's URLForDirectory:inDomain:appropriateForURL:create:error:

NSAllApplicationsDirectory
= 100, //
应用能够发生的所有路径

NSAllLibrariesDirectory
= 101, //资源可以发生的所有目录

NSTrashDirectory
NS_ENUM_AVAILABLE(10_8, NA) = 102 //
垃圾存放目录

};

NSHomeDirectory（）只能到达用户的主目录

打印结果： /Users/yinsuke/Library/Application Support/iPhone Simulator/6.0/Applications/FB3B8EAF-63D9-4CFE-878C-2692093CC763

NSString *tempPath = NSTemporaryDirectory();

/Users/yinsuke/Library/Application Support/iPhone Simulator/6.0/Applications/FB3B8EAF-63D9-4CFE-878C-2692093CC763/tmp/

NSString *fullName=NSFullUserName();

当前用户的一个完整用户名，在需要的路径下可以插入进去。

NSString *userName=NSUserName();

返回当前用户的登陆用户名

NSString * NSHomeDirectoryForUser ( NSString *userName );

返回指定用户名的用户根目录（home）

NSString * NSOpenStepRootDirectory (void);

返回当前用户的系统根目录
