RotateWorldTest对层动作

init()和onEnter()这俩个方法都是CCNode的方法。其区别如下：

 

1.其被调用的顺序是先init()，后onEnter()。

 

2.init()在类的初始化时只会调用一次。

 

3.onEnter在该类被载入场景的时候被调用，可能会发生多次。

 

4.CCLayer* cclayer = new MyLayer();

这种情况下，只会触发onEnter。

 

5.CCLayer* cclayer = MyLayer::create();

这样情况下，既会触发init()方法，也会触发onEnter()方法。
