A protocol works. Declaring the methods without implementing them also works. For properties you can use @dynamic to tell the compiler that the property's implementation is handled elsewhere (via forwarding, in your case). > And what happens with synthesis for properties declared in protocols? Nothing. The class implementation must have some explicit code to get a property implementation. Merely conforming to a protocol never adds code to your class. -- Greg Parker gpar...@apple.com Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
