有的同学建议先上图，好吧，先上效果图

再看代码，创建了两个CCControlSlider在主窗口中

// on "init" you need to initialize your instancebool ControlSlider01::init(){    //////////////////////////////    // 1. super init first    if ( !MenuLayer::init() )    {        return false;    }            CCSize screenSize = CCDirector::sharedDirector()->getWinSize();        // Add the slider    CCControlSlider *slider = CCControlSlider::create("extensions/sliderTrack.png","extensions/sliderProgress.png" ,"extensions/sliderThumb.png");    slider->setAnchorPoint(ccp(0.5f, 1.0f));    slider->setMinimumValue(0.0f); // Sets the min value of range    slider->setMaximumValue(5.0f); // Sets the max value of range    slider->setPosition(ccp(screenSize.width / 2.0f, screenSize.height / 2.0f + 16));    slider->setTag(1);        // When the value of the slider will change, the given selector will be call    slider->addTargetWithActionForControlEvents(this, cccontrol_selector(ControlSlider01::valueChanged), CCControlEventValueChanged);        CCControlSlider *restrictSlider = CCControlSlider::create("extensions/sliderTrack.png","extensions/sliderProgress.png" ,"extensions/sliderThumb.png");    restrictSlider->setAnchorPoint(ccp(0.5f, 1.0f));    restrictSlider->setMinimumValue(0.0f); // Sets the min value of range    restrictSlider->setMaximumValue(5.0f); // Sets the max value of range    restrictSlider->setMaximumAllowedValue(4.0f);    restrictSlider->setMinimumAllowedValue(1.5f);    restrictSlider->setValue(3.0f);    restrictSlider->setPosition(ccp(screenSize.width / 2.0f, screenSize.height / 2.0f - 24));    restrictSlider->setTag(2);    //same with restricted    restrictSlider->addTargetWithActionForControlEvents(this, cccontrol_selector(ControlSlider01::valueChanged), CCControlEventValueChanged);        addChild(slider);    addChild(restrictSlider);    return true;}void ControlSlider01::valueChanged(CCObject* obj, CCControlEvent){    CCControlSlider* slider = (CCControlSlider*)obj;    float val = slider->getValue();    CCLOG("%f", val);}

简单的创建了两个CCControlSlider
