接着 努力 向你 看齐 ！！

没太理解你的思路… 不过

想ls,试试nsfilemanager就可以了, 我就在这个帖子后面的帖子里面有用,不过没尝试过在iphone上用.你可以尝试一下,可能会不好使, 因为iphone的沙箱设计, 试试吧

if ((dp = opendir(path)) == NULL) {
err_sys(“can`t open %s”, path);
}

while ((dirp = readdir(dp)) != NULL) {
printf(“%s\n”, dirp->d_name);
//打印出当前目录下的所有文件或文件夹，如果时文件夹的话，用户点一下，就把文件夹的路径作为当前的path，以后//的显示操作又是这样
}

closedir(dp);

PS:不知道这样行不行的通，上面那段代码是相当于unix的命令ls，我不了解iphone的文件目录结构，不知道行不行？

不过你可以自己写阿~~
如果只是string文件, 那也不过是[NSString stringWithContentsOfFile:< #(NSString *)path#> encoding:< #(NSStringEncoding)enc#> error:< #(NSError **)error#>].
如果是raw data, 就是[NSData dataWithContentsOfFile:< #(NSString *)path#> options:< #(NSDataReadingOptions)readOptionsMask#> error:< #(NSError **)errorPtr#>]
