spdocumentlibrary 存储的文件存在物理路径吗

　　1、模拟器沙盒目录
文件都用户名文件夹隐藏文件夹文叫资源库目录其实Library

应用沙箱（sandbox）文件读写权限受限制能几目录读写文件：
Documents：应用用户数据放iTunes备份恢复候包括目录
tmp：存放临文件iTunes备份恢复目录目录文件能应用退删除
Library/Caches：存放缓存文件iTunes备份目录目录文件应用退删除

iTunes与iPhone同步备份所DocumentsLibrary文件
iPhone重启丢弃所tmp文件

查看：
1、设置显示隐藏文件Finder直接打设置查看隐藏文件：打终端输入命名
(1)显示Mac隐藏文件命令：defaults write com.apple.finder AppleShowAllFiles -bool true
(2)隐藏Mac隐藏文件命令：defaults write com.apple.finder AppleShowAllFiles -bool false
(3)输完单击Enter键退终端重新启Finder 重启Finder：鼠标单击窗口左角苹标志-->强制退-->Finder-->
现能看资源库文件夹
打资源库找/Application Support/iPhone Simulator/文件夹面模拟器各程序沙盒目录
2、种更便Finder点->前往->前往文件夹输入/Users/username/Library/Application Support/iPhone Simulator/ 前往
username写用户名
　　
　　代码查看目录：

　　NSString *path = NSHomeDirectory();//主目录
NSLog(@"NSHomeDirectory:%@",path);
NSString *userName = NSUserName();//与面相同
NSString *rootPath = NSHomeDirectoryForUser(userName);
NSLog(@"NSHomeDirectoryForUser:%@",rootPath);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory=[paths objectAtIndex:0];//Documents目录
NSLog(@"NSDocumentDirectory:%@",documentsDirectory);

return NO;
}
这种提问感觉没有意义
这个可以自己找下资料
