正文:
UIViewAnimationOptionLayoutSubviews//提交动画的时候布局子控件,表示子控件将和父控件一同动画。
UIViewAnimationOptionAllowUserInteraction//动画时允许用户交流,比如触摸
UIViewAnimationOptionBeginFromCurrentState//从当前状态开始动画
UIViewAnimationOptionRepeat//动画无限重复
UIViewAnimationOptionAutoreverse//执行动画回路,前提是设置动画无限重复
UIViewAnimationOptionOverrideInheritedDuration//忽略外层动画嵌套的执行时间
UIViewAnimationOptionOverrideInheritedCurve//忽略外层动画嵌套的时间变化曲线
UIViewAnimationOptionAllowAnimatedContent//通过改变属性和重绘实现动画效果,如果key没有提交动画将使用快照
UIViewAnimationOptionShowHideTransitionViews//用显隐的方式替代添加移除图层的动画效果
UIViewAnimationOptionOverrideInheritedOptions//忽略嵌套继承的�选项
//时间函数曲线相关
UIViewAnimationOptionCurveEaseInOut//时间曲线函数,缓入缓出,中间快
UIViewAnimationOptionCurveEaseIn//时间曲线函数,由慢到特别快(缓入快出)
UIViewAnimationOptionCurveEaseOut//时间曲线函数,由快到慢(快入缓出)
UIViewAnimationOptionCurveLinear//时间曲线函数,匀速
//转场动画相关的
UIViewAnimationOptionTransitionNone//无转场动画
UIViewAnimationOptionTransitionFlipFromLeft//转场从左翻转
UIViewAnimationOptionTransitionFlipFromRight//转场从右翻转
UIViewAnimationOptionTransitionCurlUp//上卷转场
UIViewAnimationOptionTransitionCurlDown//下卷转场
UIViewAnimationOptionTransitionCrossDissolve//转场交叉消失
UIViewAnimationOptionTransitionFlipFromTop//转场从上翻转
UIViewAnimationOptionTransitionFlipFromBottom//转场从下翻转
