如何获取块的属性？

AcDbObjectIterator *

attributeIterator() const;

This function creates a new AcDbObjectIterator set to iterate over the attributes of the block reference, and then returns a pointer to the iterator object just created. The calling application is responsible for deallocating the iterator object using the C++ delete operator.

看这个行吗！
