CALayer almost certainly does, because it functions as an extensible KVC container (basically, it's like a dictionary in that you can call -setValue:forKey: with any key your heart desires). Graham, the docs for -valueForKey: imply that it will work with any type, object or not: http://developer.apple.com/library/ios/documentation/cocoa/conceptual/KeyValueCoding/Articles/DataTypes.html But CFTypes *are* NSObjects. So I'm not sure why your case isn't working. Can you be more specific? --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
