变速类行为

这类行为的作用就是改变另一行为的速度，基类是CCEaseAction，继承自CCActionInterval。

CCEaseIn  由慢至快

CCEaseOut  由快至慢

CCEaseInOut  由快至慢再由慢至快

CCEaseSineIn  由快至慢

CCEaseSineOut  由慢至快

CCEaseSineInOut  由快至慢再由慢至快

CCEaseExponentianIn  由极快至慢

CCEaseExponentianOut  由慢至极快

CCEaseExponentianInOut  由极快至慢再由慢至极快

CCActionmanager

这个类其实并不属于行为类，它的父类是NSObject，而不是CCAction，但它又与CCAction密不可分，因此在这里单独介绍下。

CCActionmanager是个标准的单例类，它的作用顾名思义，就是管理行为类的对象，工作原理是：当节点执行runAction时，会把action通过addAction方法将对象传递给CCActionmanager的单例，该实例再把这个action添加到自己的行为序列中。CCActionmanager通过schedule定时刷新自己的update方法，在这个方法中去调用行为序列中每个action的step（会有一些筛选条件，比如暂停的行为不会update），这些step方法再根据自身的完成进度去update或是结束行为。就是说实际上是由CCActionmanager驱动的每个action去更新自己的逻辑，而runAction方法只是将行为对象添加进CCActionmanager的更新队列罢了。当节点被清除或是行为结束时，CCActionmanager会自动将action从队列中剔除，无需开发者操心。
