In my iOS app, I create a directory in the user’s Documents directory, and then later iterate the contents of that directory. The problem is that on iOS, that directory has a path like “/var/stuff/Documents/Dir”, and when I iterate it, the resulting contents have paths like “/private/var/stuff/Documents/Dir/item”.
This is fine, except that there comes a point where I have to compare my original “/var/…” path to one of the ones I've found, and get the relative part. This fails, since my path starts with "/var", and the items' paths start with "/private". Is there a way to normalize a path such that any symbolic links in it are resolved and the "real" path is created? I tried -[NSURL URLByResolvingSymlinksInPath], but that either doesn't work, or strips off the "/private" of the result. That is, I get a "/var" path. Alternatively, I can strip "/private" off any path I get while iterating, but that strikes me as fragile. Oh, it turns out I can use -URLByResolvingSymlinksInPath on the items returned while iterating the directory. Whatever it is, it's messy. -- Rick
