1、继承自CCObject

class CC_DLL CCArray : public CCObject

2、如果通过create创建，会加入自动释放池，通过new创建则不会，所以使用时要记得retain，然后释放时 使用release。

CCArray* CCArray::create(){    CCArray* pArray = new CCArray();    if (pArray && pArray->init())    {        pArray->autorelease();    }    else    {        CC_SAFE_DELETE(pArray);    }        return pArray;}

3、addObject 增加一个，会调用retain

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);}--》ccArrayAppendObject/** 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(); //retain对象	arr->arr[arr->num] = object;	arr->num++;}

4、 移除其中一个，默认会release

/** Remove a certain object */void removeObject(CCObject* object, bool bReleaseObj = true);//实现：void CCArray::removeObject(CCObject* object, bool bReleaseObj/* = true*/){    ccArrayRemoveObject(data, object, bReleaseObj);}-->>/** Searches for the first occurrence of object and removes it. If object is not found the function has no effect. */void ccArrayRemoveObject(ccArray *arr, CCObject* object, bool bReleaseObj/* = true*/){	unsigned int index = ccArrayGetIndexOfObject(arr, object);	if (index != CC_INVALID_INDEX)    {		ccArrayRemoveObjectAtIndex(arr, index, bReleaseObj);    }}-->>ccArrayRemoveObjectAtIndex/** Removes object at specified index and pushes back all subsequent objects. Behavior undefined if index outside [0, num-1]. */void ccArrayRemoveObjectAtIndex(ccArray *arr, unsigned int index, bool bReleaseObj/* = true*/){    CCAssert(arr && arr->num > 0 && index < arr->num, "Invalid index. Out of bounds");    if (bReleaseObj)    {        CC_SAFE_RELEASE(arr->arr[index]); //release    }    	arr->num--;		unsigned int remaining = arr->num - index;	if(remaining>0)    {		memmove((void *)&arr->arr[index], (void *)&arr->arr[index+1], remaining * sizeof(CCObject*));    }}

5、移除全部，都会release

void CCArray::removeAllObjects(){    ccArrayRemoveAllObjects(data);}-->>/** Removes all objects from arr */void ccArrayRemoveAllObjects(ccArray *arr){	while( arr->num > 0 )    {		(arr->arr[--arr->num])->release();    }}

6、析构

CCArray::~CCArray(){    ccArrayFree(data);}-->>/** Frees array after removing all remaining objects. Silently ignores NULL arr. */void ccArrayFree(ccArray*& arr){    if( arr == NULL )     {        return;    }	ccArrayRemoveAllObjects(arr);		free(arr->arr);	free(arr);    arr = NULL;}
