The documentation for NSDictionary seems incomplete. Where can I find a complete version?
For instance, where do I find the documentation which fully explains keysSortedByValueWithOptions:usingComparator:. The docs with iOS 4.3 fail to define what “options” there are.
Those are the docs; you can often find other tidbits of information doing a web search (http://cocoadev.com is a good resource, as is SO, of course), but there’s no “more complete” version of the Apple documentation.
For this particular case, a search for “sort options” turns up the Foundation Constants Reference, which contains an
enumof Sort Options.Interestingly, I just noticed that
-[NSArray enumerateObjectsWithOptions:usingBlock:]does explain the available options, so this is definitely an oversight. You should send in a doc bug report
