Use the various NSBundle methods (bundleForClass: is good).
Given that you are looking at localization the function NSLocalizedStringFromTableInBundle might also be helpful.
Table placed in ImageIO, no classes there, so i cant use bundleForClass:. May be i dont need to point ImageIO bundle? Another one?Did you look at the method I suggested? Given the name bundleForClass: what do you think it does (hint if you supply a class what do you think it returns)? I'm not going to spoon-feed you answers any further than that.
