Delete Double Pointer for the CCSprite?

I am using double pointer for the CCSprite. For the pointer to pointer I am doing new and for then creating then using cocos2d usual method create How should I delete the double pointer in following case

 CCSprite **mCBg;

 mCBg = new CCSprite*[mNumberBackgound];

//for loop for creating sprites 
 mCBgLayer[i]= CCSprite::create("Sprites/level1.png");

Since Create automatically adds to the memory pool

What about the Objects created using 'new' how to delete them in destructor 

 if(mCBg)
{
    CC_SAFE_DELETE_ARRAY(mCBgLayer);
}

If I do this I get crash in destructor Please give answer with explanation. So i can understand the memory management of cocos2d-x

Solution

  • Cocos2d-x use Reference Count and AutoReleasePool to manage memory.

    The function CCSprite::create() 's implementation used autorelease().You do not need to release the memory, or the reference count will be smaller than 0;More detail see: http://www.cocos2d-x.org/projects/cocos2d-x/wiki/Reference_Count_and_AutoReleasePool_in_Cocos2d-x
