I can't agree. _This_ is easy:
url = [url URLByResolvingSymlinksInPath];
_this_ is a PITA:
- (NSURL*)URLByResolvingSymlinksAndAliases
{
NSURL* resultURL = [self URLByResolvingSymlinksInPath];
NSError* error = nil;
NSNumber* isAliasFile = nil;
BOOL success = [resultURL getResourceValue:&isAliasFile
forKey:NSURLIsAliasFileKey
error:&error];
if (success && [isAliasFile boolValue])
{
NSData* bookmarkData = [NSURL
bookmarkDataWithContentsOfURL:resultURL
error:&error];
if (bookmarkData)
{
BOOL isStale = NO;
NSURLBookmarkResolutionOptions options =
(NSURLBookmarkResolutionWithoutUI |
NSURLBookmarkResolutionWithoutMounting);
NSURL* resolvedURL = [NSURL
URLByResolvingBookmarkData:bookmarkData
options:options
relativeToURL:nil
bookmarkDataIsStale:&isStale
error:&error];
if (resolvedURL)
{
resultURL = resolvedURL;
}
}
}
return resultURL;
}
Especially since, again, the Mac UI doesn't even let you create
symlinks, but does let you create aliases. It seems to me the symlink
case should be the convoluted case.
But, as you say, category methods are a nice thing to have!
Thanks,
