Here is a small code sample to list the names and arguments of all methods  
an object can respond to. Note that method_name is a selector, which is  
then mapped to the ASCII name with sel_getName. method_types has a complex  
encoding mechanism that includes the return value type, followed by a list  
of argument coding characters and distances from the stack pointer. It's  
better to use the runtime method_xxx() calls to get this information.

       }
      classInfo = classInfo->super_class;
    }
    return self;
  }
