Obtengo un "Desaparecido el contexto para la declaración de método" para mi método de descripción reemplazado. ¿Puedes decir lo que está mal con el código?"Falta el contexto para la declaración de método" para el método de descripción reemplazado
#import <Foundation/Foundation.h>
#import "BNRItem.h"
int main(int argc, const char * argv[])

Gracias. He movido el método de descripción a BNRItem.m, pero ahora tengo un conjunto diferente de problemas. Han pegado en BNRItem.m arriba. – pdenlinger
