NSFileManager:enumeratorAtURL: returns a different form of URL to NSFileManager:URLForDirectory

If I fetch my sandbox's Application Support directory using `NSFileManager:URLForDirectory` then I get back the following URL: ``` file://localhost/var/mobile/Applications/EA80DE91-394C-4EAB-B269-1081C859BB0F/Library/Application%20Support/ ``` However if I use `NSFileManager:enumeratorAtURL` to search the directory I get back URLs of the form: ``` file://localhost/private/var/mobile/Applications/EA80DE91-394C-4EAB-B269-1081C859BB0F/Library/Application%20Support/ ``` This is causing me problems because I'm doing URL search/replace manipulations and the difference causes a mismatch. I've run into this sort of difference elsewhere previously and my solution then was to use the path of the urls (using `NSURL:path`) instead of the raw URLs, however that won't work in this situation as the paths produced are: ``` /var/mobile/Applications/EA80DE91-394C-4EAB-B269-1081C859BB0F/Library/Application Support /private/var/mobile/Applications/EA80DE91-394C-4EAB-B269-1081C859BB0F/Library/Application Support/ ``` What I am trying to do is this: I can have any number of files in my Application Support directory with the same name but different locations, and I need to extract the path relative to the Application Support directory. i.e. if I have the following ``` /Application Support/abc/file.dat /ApplicationSupport/abc/def/file.dat ``` I want to be able to extract "abc" and "abc/def". I was doing this using the following code: ``` NSArray *keys = [NSArray arrayWithObject:NSURLIsRegularFileKey]; NSDirectoryEnumerator *dirEnumerator = [self.fileManager enumeratorAtURL:[MyManager appSupportDirectory] includingPropertiesForKeys:keys options:NSDirectoryEnumerationSkipsHiddenFiles errorHandler:nil]; for (NSURL *url in dirEnumerator) { if ( NSOrderedSame == [[url lastPathComponent] caseInsensitiveCompare:kFilename]) { NSString *appSupportPath = [[MyManager appSupportDirectory] path]; NSString *pathToFile = [url path]; pathToFile = [pathToFile URLByDeletingLastPathComponent]; NSString *subPath = [pathToFile stringByReplacingOccurrencesOfString:appSupportPath withString:@""]; ``` (MyManager:appSupportDirectory calls NSFileManager:URLForDirectory: using NSApplicationSupportDirectory) This works fine on the simulator where `enumeratorAtURL:` and `URLFOrDirectory:` return identical paths, but due to their differences on hardware it fails. Is there a way to get `enumeratorAtURL:` and `URLForDirectory:` to return identical paths, or if not is there an alternative elegant way of extracting the subpaths to what I am currently doing?
