1.使用方法：
1）如果尚未建立场景（即游戏中的第一个场景），就是用pDirector->runWithScene(pScene);即可以使用相应场景，
CCDirector *pDirector = CCDirector::sharedDirector();
pDirector->setOpenGLView(CCEGLView::sharedOpenGLView());
pDirector->setDisplayStats(true);
CCScene * pScene = CCScene::create();
CCLayer * pLayer = new TestController();
pLayer->autorelease();
pScene->addChild(pLayer);
pDirector->runWithScene(pScene);
2）如果是替换场景，则使用CCDirector::sharedDirector()->replaceScene(this);替换相应的场景即可
void AccelerometerTestScene::runThisTest()
{
CCLayer* pLayer = new AccelerometerTest();
addChild(pLayer);
pLayer->release();
<span style="color:#ff0000;"> CCDirector::sharedDirector()->replaceScene(this);</span>
}而如果要使用场景间的切换效果来切换场景，则需要使用相应的切换方法即transitionWithDuration（当然不同效果的使用方法略有不同）生成相应场景，然后再通过CCDirector::sharedDirector()->replaceScene(this)来启动场景，也就是说这个给这个场景加了一个外包装，然后再启动，那么，这个场景就不是直接显示了，而是在场景的效果使用完了以后进入场景，起到过渡的效果。
一般此函数有两个参数，第一个是特效的切换时间，直接生成一个CCTime即可，例子中设定的时间是1.2s，对于很多场景的显示都很舒服，第二个是要进入的场景，有的会有第三个参数，会在下面介绍
2.test中的效果总结 CCTransitionJumpZoom::transitionWithDuration(t,s);//跳跃式，本场景先会缩小，然后跳跃进来 CCTransitionFade::transitionWithDuration(t,s);//淡出淡入，原场景淡出，新场景淡入 CCTransitionFade::transitionWithDuration(t,s,ccWHITE);//如果上一个的函数，带3个参数，则第三个参数就是淡出淡入的颜色 CCTransitionFlipX::transitionWithDuration(t,kOrientationLeftOver);//x轴左翻 CCTransitionFlipX::transitionWithDuration(t,kOrientationRightOver);//x轴右翻 CCTransitionFlipY::transitionWithDuration(t,kOrientationUpOver);//y轴上翻 CCTransitionFlipY::transitionWithDuration(t,kOrientationDownOver);//y轴下翻 CCTransitionFlipAngular::transitionWithDuration(t,kOrientationLeftOver);//有角度转的左翻 CCTransitionFlipAngular::transitionWithDuration(t,kOrientationRightOver);//有角度转的右翻 CCTransitionZoomFlipX::transitionWithDuration(t,kOrientationLeftOver);//带缩放效果x轴左翻 CCTransitionZoomFlipX::transitionWithDuration(t,kOrientationRightOver);//带缩放效果x轴右翻 CCTransitionZoomFlipY::transitionWithDuration(t,kOrientationUpOver);//带缩放效果y轴上翻 CCTransitionZoomFlipY::transitionWithDuration(t,kOrientationDownOver);//带缩放效果y轴下翻 CCTransitionZoomFlipAngular::transitionWithDuration(t,kOrientationLeftOver);//带缩放效果/有角度转的左翻 CCTransitionZoomFlipAngular::transitionWithDuration(t,kOrientationRightOver);//带缩放效果有角度转的右翻 CCTransitionShrinkGrow::transitionWithDuration(t,s);//交错换 CCTransitionRotoZoom::transitionWithDuration(t,s);//转角换 CCTransitionMoveInL::transitionWithDuration(t,s);//新场景从左移入覆盖 CCTransitionMoveInR::transitionWithDuration(t,s);//新场景从右移入覆盖 CCTransitionMoveInT::transitionWithDuration(t,s);//新场景从上移入覆盖 CCTransitionMoveInB::transitionWithDuration(t,s);//新场景从下移入覆盖 CCTransitionSlideInL::transitionWithDuration(t,s);//场景从左移入推出原场景 CCTransitionSlideInR::transitionWithDuration(t,s);//场景从右移入推出原场景 CCTransitionSlideInT::transitionWithDuration(t,s);//场景从上移入推出原场景 CCTransitionSlideInB::transitionWithDuration(t,s);//场景从下移入推出原场景 以下三个需要检测opengl版本是否支持CCConfiguration::sharedConfiguration()->getGlesVersion() <= GLES_VER_1_0如果为真则为不支持 CCTransitionCrossFade::transitionWithDuration(t,s);//淡出淡入交叉，同时进行 CCTransitionRadialCCW::transitionWithDuration(t,s);//顺时针切入 CCTransitionRadialCW::transitionWithDuration(t,s);//逆时针切入 以下两个需要先设置摄像机，使用CCDirector::sharedDirector()->setDepthTest(true); CCTransitionPageTurn::transitionWithDuration(t,false);//翻页，前翻 CCTransitionPageTurn::transitionWithDuration(t,true);//翻页，后翻 CCTransitionFadeTR::transitionWithDuration(t,s);//向右上波浪 CCTransitionFadeBL::transitionWithDuration(t,s);//向左下波浪 CCTransitionFadeUp::transitionWithDuration(t,s);//向上百叶窗 CCTransitionFadeDown::transitionWithDuration(t,s);//向下百叶窗 CCTransitionTurnOffTiles::transitionWithDuration(t,s);//随机小方块 CCTransitionSplitRows::transitionWithDuration(t,s);//按行切 CCTransitionSplitCols::transitionWithDuration(t,s);//按列切
