fileManager的基本应用：查看列表
NSFileManager *fileManager=[NSFileManager defaultManager];
NSArray *documentPaths=NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory,NSAllDomainsMask , YES);
for (NSString *str in documentPaths) {
NSLog(@"documentPaths:%@",str);
}
NSString *documentDir=[documentPaths objectAtIndex:0] ;
NSLog(@"documentDir:%@",documentDir);
结果如下：
2013-06-14 16:30:48.253 helloword[1092:c07] documentPaths:/Users/qing/Library/Application Support/iPhone Simulator/6.1/Applications/A3EEDA4B-0F5E-49E5-91D8-FBCCD388B539/Library/Documentation 2013-06-14 16:30:48.258 helloword[1092:c07] documentPaths:/Library/Documentation 2013-06-14 16:30:48.258 helloword[1092:c07] documentPaths:/Network/Library/Documentation 2013-06-14 16:30:48.259 helloword[1092:c07] documentPaths:/System/Library/Documentation 2013-06-14 16:30:48.260 helloword[1092:c07] documentDir:/Users/qing/Library/Application Support/iPhone Simulator/6.1/Applications/A3EEDA4B-0F5E-49E5-91D8-FBCCD388B539/Library/Documentation
NSSearchPathForDirectoriesInDomains：
NSArray *documentPaths=NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory,NSUserDomainMask , YES);
//documentPaths:/Users/qing/Library/Application Support/iPhone Simulator/6.1/Applications/A3EEDA4B-0F5E-49E5-91D8-FBCCD388B539/Library/Documentation
documentPaths=NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory,NSAllDomainsMask , YES);
///Users/qing/Library/Application Support/iPhone Simulator/6.1/Applications/A3EEDA4B-0F5E-49E5-91D8-FBCCD388B539/Downloads
