UIview简单动画

一 Core Animation
    核心动画是分三层进行的-动画层树（CALayer Tree）M、展示树（Presentation Tree）、以及渲染树（Render Tree）。
    每一个动画层有着自己的坐标系，这个坐标系独立于其父动画层。在iOS上，动画层的坐标系原点在左上角，坐标轴向右向下延伸。
    动画有隐式和显示之分。隐式动画指的是，无须创建动画对象，只需改变动画层的属性，让核心动画自己去完成动画效果。显示动画指的是，需要自己创建和管理动画对象，并且将它们应用到动画层，才能显示动画效果。
    UIImageView有animationImages属性，如果将一个UIImage对象构成的NSArray数组赋值给它，UIImageView将轮流显示这些图像。给UIImageView发送startAnimating消息，那么它就开始逐帧显示动画了。animationDuration属性标明了每一帧动画占用的时间，默认1/30秒。animationRepeatCount属性标明了动画重复次数，缺省为0，表示不断重复下去。
方法：
    +beginAnimations:context:标志动画代码开始
    +commitAnimations:标志动画代码结束，程序会创建新的线程，并准备运行动画
    +setAnimationStartDate:设置动画开始时间。
    +setAnimationsEnabled:可以用来开启或禁止动画显示。
    +setAnimationDelegate:设置代理，可以接收到UIView的代理方法。
    +setAnimationWillStartSelector:设置动画开始前将发送给代理的方法。
    +setAnimationDidStopSelector:设置动画停止后将发送给代理的方法。
    +setAnimationDuration:设置动画持续时间。
    +setAnimationDelay:设置一段时间，动画将在这段时间后开始执行。不建议使用
    +setAnimationCurve:设置动画曲线，如开始慢，后面快。
    +setAnimationRepeatCount:设置动画重复次数。
    +areAnimationEnabled:检查是否已经启动动画。
