Any object can be a key in an NSDictionary, but NSDictionary always copies its keys. Its toll--free bridged companion, CFDictionary, can be configured to just retain/release the keys instead. > [sourceButtonMap setObject:[NSString stringWithString:@"no"] > forKey:[unitButton description]]; This is a bad idea. Who knows what -description returns? Using a textual description of an object intended for debugging in place of the actual object is needlessly complex and just plain wrong. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
