Xamarin.iOS exportará las interfaces con este atributo como protocolo a Objective-C, y las clases que implementen estas interfaces se marcarán como la implementación del protocolo correspondiente cuando se exporten a Objective-C.

// This will create an Objective-C protocol called 'IMyProtocol', with one required member ('requiredMethod')
[Protocol ("IMyProtocol")]
interface IMyProtocol
{
  [Export ("requiredMethod")]
  void RequiredMethod ();
}

// This will export the equivalent of "@interface MyClass : NSObject <IMyProtocol>" to Objective-C.
class MyClass : NSObject, IMyProtocol
{
  void RequiredMethod ()
  {
  }
}
