Depends on your requirements… If performance isn’t critical, just call -rangeOfData: on each search string, then pick the match with the minimum location. (If you don’t know whether performance will be critical, do it this way anyway and then profile the app to see if it’s fast enough.) If that’s not fast enough, and the data is text, NSRegularExpression might be faster. You’ll need to construct a regex of the form “foo|bar|baz”, i.e. the search strings separated with “|”. Metachars in the search strings need to be escaped. The actual search should be fast, but constructing the regex will have some overhead. If neither of those is good enough, then you may have to crack open some books (or search Github) to find a multiple string search algorithm. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
