I don't understand that. The search pattern for valueForKey: is documented very clearly and if you have a myColor method or a _myColor instance variable, as you surely must, it should find it and return it. The only question from reading the documentation is .. what should it return it as? Were that the issue, it having a problem converting a CGColorRef to something it can return, I'd not expect valueForUndefinedKey: but some other exception. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
