请教各位一个问题：
删除图块对应的属性，下面的程序是否正确
AcDbObjectPointer spBlkRef(objId,AcDb::kForWrite);
if(spBlkRef.openStatus() != Mcad::eOk)  return;
AcDbObjectIterator* pAttribIter = spBlkRef->attributeIterator();
if(pAttribIter != NULL)
{
      for(;!pAttribIter->done();pAttribIter->step() )
      {
            AcDbObjectPointer spAttribute(pAttribIter->objectId(),AcDb::kForWrite);
            if (spAttribute.openStatus() != Mcad::eOk)
            {
                     continue;
            }
            spAttribute->erase(true);
            spAttribute->close();
      }
      delete pAttribIter;
}
spBlkRef->close();
按照上面的程序删除后，再用鼠标选择上面的实体会报错，而且再遍历此图块的属性时，它的属性并没有被删除掉，只是spAttribute.openStatus() != Acad::eOk了

采用如下的方式添加的属性：
                           AcDbAttribute* pAttrib2 = new AcDbAttribute;
                              AcGePoint3d start1 = spBlkRef->position();
                              AcGePoint3d start3(start1.x,start1.y-13,0);
                              pAttrib2->setTag(_T("attrBH"));
                              pAttrib2->setAlignmentPoint(start3);
                              pAttrib2->setHorizontalMode(McDb::kTextCenter);
                              pAttrib2->setTextString(tmpBh);
                              pAttrib2->setHeight(5);
                              pAttrib2->setWidthFactor(1);
                              pAttrib2->setTextStyle(wordsId);
                              pAttrib2->setInvisible(FALSE);
                              spBlkRef->appendAttribute(pAttrib2);
                              pAttrib2->close();
