cocos2d-x的CCArray用法

一.基本用法

1.声明初始化变量

C++

1 2 3

cocos2d :: CCArray * pArray ; pArray = CCArray :: createWithCapacity ( 100 ) ; pArray -> retain ( ; //如果保留成员变量的话,此处必须retain,否则会崩溃,因为标记了autorelease

2.添加元素到数组

C++

1 2	CCSprite * pRet = CCSprite :: create ( "test.png" ) ; pArray -> addObject ( pRet ; //将pRet添加到数组0位置,此处会调用一次pRet的retain

3.删除元素

1

2

3

//下面这两个函数都能够实现删除元素的效果

pArray removeObject ( pRet //第二参数为是否调用release,默认为true

pArray removeObjectAtIndex 0 //删除o位置上的元素

4.遍历

1).使用ccarray中的宏进行遍历
