本实例演示了同时使用CCRotateTo，CCSkewTo,CCScaleTo来实现动态效果，代码如下

    CCSize boxSize = CCSizeMake(100.0f, 100.0f);
    //在场景中添加一个背景为黄色的矩形
    CCLayerColor *box = CCLayerColor::create(ccc4(255, 255, 0, 255));
    box->setAnchorPoint(ccp(0, 0));
    box->setPosition(ccp(190, 110));
    box->setContentSize(boxSize);

    //在上面的黄色矩形左上角添加一个矩形
    static float markrside = 10.0f;
    CCLayerColor *uL = CCLayerColor::create(ccc4(255, 0, 0, 255));
    box->addChild(uL);
    uL->setContentSize(CCSizeMake(markrside, markrside));
    uL->setPosition(ccp(0.f, boxSize.height - markrside));
    uL->setAnchorPoint(ccp(0, 0));

    //在上面的黄色矩形右上角添加一个矩形
    CCLayerColor *uR = CCLayerColor::create(ccc4(0, 0, 255, 255));
    box->addChild(uR);
    uR->setContentSize(CCSizeMake(markrside, markrside));
    uR->setPosition(ccp(boxSize.width - markrside, boxSize.height - markrside));
    uR->setAnchorPoint(ccp(0, 0));
    addChild(box);

    //使用CCRotateTo，CCSkewTo,CCScaleTo来实现动态效果
    CCActionInterval *actionTo = CCSkewTo::create(2, 0.f, 2.f);
    CCActionInterval *rotateTo = CCRotateTo::create(2, 61.0f);
    CCActionInterval *actionScaleTo = CCScaleTo::create(2, -0.44f, 0.47f);

    CCActionInterval *actionScaleToBack = CCScaleTo::create(2, 1.0f, 1.0f);
    CCActionInterval *rotateToBack = CCRotateTo::create(2, 0);
    CCActionInterval *actionToBack = CCSkewTo::create(2, 0, 0);

    box->runAction(CCSequence::create(actionTo, actionToBack, NULL));
    box->runAction(CCSequence::create(rotateTo, rotateToBack, NULL));
    box->runAction(CCSequence::create(actionScaleTo, actionScaleToBack, NULL));

效果图如下：
