cocos2dx引用计数和autorelease

概述cocos2dx实现引用计数 GameObject.h #ifndef __GameObject_H__#define __GameObject_H__class GameObject{public: GameObject(); ~GameObject(); int _iCount; void myFree(); };#endif GameObject.cpp #i

cocos2dx实现引用计数

GameObject.h

#ifndef __GameObject_H__#define __GameObject_H__class GameObject{public:	GameObject();	~GameObject();	int _iCount;	voID myFree();	};#endif

GameObject.cpp

#include "GameObject.h"#include "cocos2d.h"USING_NS_CC;GameObject::GameObject(){	_iCount = 1;}GameObject::~GameObject(){}voID GameObject::myFree(){	--_iCount;	if (_iCount<=0)	{		delete this;	}		log("====shuchu _iCount = %d",_iCount);}

下面是c++和c语言的申请内存和释放内存的用法示例

cocos2dx实现引用计数//C++:如果调用delete就一定会去调用析构函数//如果调用new就一定会去调用构造函数	GameObject* gameObject = new GameObject();	gameObject->_iCount = 1;	delete gameObject; //调用delete就会马上去执行析构函数	GameObject* gameObject2 = new GameObject[5];	delete[] gameObject2;	//new/delete	//new[]/delete[]//内存出错	GameObject* gameObject = new GameObject();	GameObject* gameObject2 = gameObject;  //引用同一块内存地址	gameObject->_iCount = 6;	delete gameObject;	gameObject2->_iCount = 0;	//C:malloc和free不执行构造函数和析构函数	GameObject* gameObject = (GameObject*)malloc(sizeof(GameObject));	gameObject->_iCount = 0;	free(gameObject);//这是实现引用计数	GameObject* gameObject = new GameObject();	GameObject* gameObject2 = gameObject;	gameObject->_iCount+=1;	gameObject->myFree();	gameObject->_iCount = 6;	gameObject2->_iCount = 5;	gameObject2->myFree();//autorelease是在析构的时候把所有的指针都赋为null，这样就不会//导致内存泄露
