terminate called after throwing an instance of 'std::out_of_range' what(): _Map_base::at

描述：运行右边的代码代码：Uisystem uiSystemService(xmlPath); (调用此类Uisystem 的构造函数能够能够正常运行到最后一行，调用完成构造函数之后就报错，我找了好久都没有找到原因。。。)

错误码：terminate called after throwing an instance of ‘std::out_of_range‘   what():  _Map_base::at

修改代码：Uisystem* uiSystemService = new Uisystem(xmlPath);

原因：此类Uisystem的成员变量中有包含堆上的对象地址元素的map， 所以构造此类的对象需要在堆上进行。
