Sounds like homework, you should take the first move: http://en.wikipedia.org/wiki/Objective-C

look at 2.2 Interfaces and implementations

MyClass extends Class

 @interface MyClass : Class { }
 @end

MyClass extends Class implements Interface1 & Interface2

 @interface MyClass : Class <Interface1, Interface2> {}
 @end
