When you need to filter out some file types in a NSOpenPanel, you

So it seems strange to me that there is not a message in
NSFileManager to check that a file at a filePath matches one of
the fileTypes.
ex:
- (BOOL) fileMatchesTypes:(NSArray *) fileTypes;
No I don't think it has this but you can get a NSDictionary of the
file attributes at a file path with
fileAttributesAtPath:traverseLink: and use the NSFileManager's
fileType category addition to it to get the file type, which you
can then compare to your file types.
Am I missing something or is it a job for Bug Reporter
(Enhancement Request)?
Might be worth it but in the mean time you write your own category
to NSFileManager. I would use method signiture more like -
(BOOL)fileAtPath:(NSString *)path matchesTypes:(NSArray *)fileTypes.
That's what I did (though I like your method name better than mine).
I will file an enhancement request.
I'm looking forward to the enhancement request, but
fileAtPath:matchesTypes: is something we might actually implement, and
then we'd both have a problem.
Namespacing your selector via a prefix would also be a good idea; that
way any future Foundation implementation won't stomp on yours if we
happen to pick the same mellifluous name.
