1、常用属性:
frame bounds center alpha Transition 过渡 transform 动画效果
2、常用方法:
+(void)setAnimationDelegate:(id)delegate;
+(void)setAnimationWillStartSelector:(SEL)selector; 当动画结束的时候,执行delegate对象的selector,并且把beginAnimations:context:中传入的参数传进selector
+ (void)setAnimationDidStopSelector:(SEL)selector; 当动画结束时,执行delegate对象的selector,并且把beginAnimations:context:中传入的参数传进selector
+ (void)setAnimationDuration:(NSTimeInterval)duration; 动画的持续时间,秒为单位
+ (void)setAnimationDelay:(NSTimeInterval)delay; 动画延迟delay秒后再开始
+ (void)setAnimationStartDate:(NSDate *)startDate; 动画的开始时间,默认为now
+ (void)setAnimationCurve:(UIViewAnimationCurve)curve; 动画的节奏控制(过渡)
+ (void)setAnimationRepeatCount:(float)repeatCount; 动画的重复次数
+ (void)setAnimationRepeatAutoreverses:(BOOL)repeatAutoreverses; 如果设置为YES,代表动画每次重复执行的效果会跟上一次相反
+ (void)setAnimationTransition:(UIViewAnimationTransition)transition forView:(UIView *)view cache:(BOOL)cache; 设置视图view的过渡效果, transition指定过渡类型, cache设置YES代表使用视图缓存,性能较好
