[Q] Do subclasses implementing same Protocol as super class also need to include it in declaration?

I have a class D that derives from class S. S derives from NSObject<NSCoding>. Do I need to declare D as:

	@interface D : S<NSCoding>

or can I leave off the <NSCoding> for the derived classes, and still get appropriate warnings?

TIA,

Rick
