/*
动画的属性:
animationImages;
highlightedAnimationImages;
animationDuration; 动画持续的时间
animationRepeatCount; 动画重复点击次数
动画的方法:
- (void)startAnimating;
- (void)stopAnimating;
- (BOOL)isAnimating; 是否正在播放动画

*/
/*
事件的响应
事件传递:物理屏幕 -->应用程序 -->再把事件传递给window-->视图控制器-- >view
(一旦事件阻隔比如用户交互关闭,就找不到应用程序了)
问题:如果遇到按钮点击不好用没反应,首先检查用户交互

BOOL userInteractionEnabled :表示用户交互
(UILabel,UIImageview,默认是NO,UIView默认是YES)
