SwitchControl控制項起到了一個開關的作用類似於現實生活中的開關

由於控制項比較簡單，我就不做過多的解釋，直接上代碼

首先在工程目錄下的Resource檔案夾中添加三張圖片

在SwitchControl.h添加下面代碼

#ifndef   _SwitchControl_H_#define  _SwitchControl_H_#include "cocos2d.h"#include "cocos-ext.h"USING_NS_CC;USING_NS_CC_EXT;class SwitchControl : public CCLayer {public:    static CCScene* scene();CREATE_FUNC(SwitchControl);bool init();void switchValueChanged(CCObject*, CCControlEvent);};#endif

在SwitchControl.cpp中添加下面代碼

#include "SwitchControl.h"CCScene* SwitchControl::scene(){CCScene* s = CCScene::create();SwitchControl* layer = SwitchControl::create();s->addChild(layer);return s;}bool SwitchControl::init(){     CCLayer::init();    //得到視窗的大小    CCSize winSize = CCDirector::sharedDirector()->getWinSize();       //設定ControlSwitch控制項開啟的文字No"CCLabelTTF* on = CCLabelTTF::create("ON", "Arial", 16);    //設定ControlSwitch控制項關閉時的文字"OFF"    CCLabelTTF* off = CCLabelTTF::create("OFF", "Arial", 16);    //設定ControlSwitch控制項開啟的文字的顏色    on->setColor(ccc3(0, 0, 0));    //設定ControlSwitch控制項關閉時的顏色off->setColor(ccc3(0, 0, 0));    //建立ControlSwitch控制項    CCControlSwitch* control = CCControlSwitch::create(    CCSprite::create("switch-mask.png"),    CCSprite::create("switch-on.png"),    CCSprite::create("switch-off.png"),    CCSprite::create("switch-thumb.png"),    on,    off);        //添加ControlSwitch控制項        addChild(control);              //設定ControlSwitch控制項的位置        control->setPosition(ccp(winSize.width / 2, winSize.height / 2));// 註冊valuechange訊息，當valuechange時，調用switchValueChanged函數control->addTargetWithActionForControlEvents(this, cccontrol_selector(SwitchControl::switchValueChanged), CCControlEventValueChanged);return true;}void SwitchControl::switchValueChanged(CCObject* sender, CCControlEvent ev){if (ev == CCControlEventValueChanged){CCControlSwitch* control = (CCControlSwitch*)sender;if (control->isOn()){CCLog("Switch if ON");}else{CCLog("Swith is Off");}}else{CCLog("other events");}}

執行結果：
