/** 以下为cocos2dx原码 先执行的是release,如果_data[index]与object是一个东西且ref等1

问题就来了，先删了_data[index],再retain崩溃*/

void replace(ssize_t index,T object)

{

CCASSERT(index >= 0 && index < size(),"Invalid index!");

CCASSERT(object != nullptr,"The object should not be nullptr");

_data[index]->release();

_data[index] = object;

object->retain();

}

应改为先retain再release

object->retain();

_data[index]->release();

_data[index] = object;

以上点，引用object基础编程
