cocos2d-x开启IOS多点触控

参考资料：http://www.cocos2d-x.org/projects/cocos2d-x/wiki/How_to_Enable_Multi-Touch/diff/4

在初始化代码中，开启当前层接受触摸

this->setTouchEnabled(true);

在AppController.mm文件中，设置开启多点触控

[__glView setMultipleTouchEnabled:YES];

测试一下，重写ccTouchesMoved函数，打印多点触控的位置

void HelloWorld::ccTouchesMoved(CCSet *pTouches, CCEvent *pEvent){    if(pTouches->count() >= 2)  //多点触控    {        CCSetIterator itor;        for( itor = pTouches->begin(); itor != pTouches->end(); ++itor)        {            CCTouch *pTouch = dynamic_cast<CCTouch *>(*itor);            //获得游戏坐标位置            CCPoint ccp = pTouch->getLocation();            printf("%f\t%f\n", ccp.x, ccp.y);        }        printf("\n");    }    else    //单点触控    {        CCTouch *pTouch = dynamic_cast<CCTouch *>(pTouches->anyObject());        CCPoint ccp = pTouch->getLocation();        printf("%f\t%f\n", ccp.x, ccp.y);    }}
