Cocos2d-场景切换-CCTransitionFlipX和CCTransitionFade和CCTransitionSlideInL

Cocos2d为我们提供了很多场景切换了方式。
我们只需要调用就好！
废话不多说，上代码：
1. CCTransitionFlipX场景切换
2. CCTransitionFade场景切换
3. CCTransitionSlideInL场景切换
还有很多方式，慢慢补上！
4. popScene退出场景
CCTransitionFlipX *transitionScene = [CCTransitionFlipX transitionWithDuration:1.0scene:[HelloWorldLayer scene]];
  [[CCDirector sharedDirector]replaceScene:transitionScene];
[[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:1.0scene:[HelloWorldLayer scene] withColor:ccWHITE]];
CCTransitionSlideInL *transitionScene = [CCTransitionSlideInLtransitionWithDuration:3.0 scene:[SoundSetting scene]];
    [[CCDirector sharedDirector]replaceScene:transitionScene];
[[CCDirector sharedDirector] popScene];
5. pushScene进入场景
 
[[CCDirector sharedDirector] pushScene:[HighScoreLayer scene]];
