更换节点的父节点

 

 

1 child->retain();//引用计数+1
2 
3 child->removeFromParent(); 
4 
5 root->addChild();
6 
7 child->release(); //引用计数-1

需要注意的是retain()和release(),如果在卸载节点前不调用retain的话会导致报错

CCAssert( child->m_pParent == NULL, "child already added. It can't be added again");

 

release()要和retain()成对使用，否则会引起内存泄露
