Cocos2dx 内存管理机制(3)

③所以最后的release是为了将引用计数重新变成为1。这样的话，从对象创建，到被放到对象自动管理池，引用计数依然为1，被管理值也为1（表征对象是自动管理）。

不信的话，下面我们来跟踪一下m_pManagedObjectArray->addObject(pObject)

void CCArray::addObject(CCObject* object)
{
    ccArrayAppendObjectWithResize(data, object);
}

/** Appends an object. Capacity of arr is increased if needed. */
void ccArrayAppendObjectWithResize(ccArray *arr, CCObject* object)
{
	ccArrayEnsureExtraCapacity(arr, 1);
	ccArrayAppendObject(arr, object);
}

/** Appends an object. Behavior undefined if array doesn't have enough capacity. */
void ccArrayAppendObject(ccArray *arr, CCObject* object)
{
    CCAssert(object != NULL, "Invalid parameter!");
    object->retain();
	arr->arr[arr->num] = object;
	arr->num++;
}
