🌰
<code>
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
要执行的动画
[UIView commitAnimations];
</code>
+(void)animateWithDuration:(NSTimeInterval)duration//时间 delay:(NSTimeInterval)delay//延迟 options:(UIViewAnimationOptions)options//动画方式 animations:(void (^)(void))animations//变换内容 completion:(void (^)(BOOL finished))completion//变换结束
动画效果
跟父类作为一个整体一起动画，此方式为默认方式
default
UIViewAnimationOptionLayoutSubviews
动画过程中 允许用户点击 比如button
turn on user interaction while animating
UIViewAnimationOptionAllowUserInteraction
从当前状态开始动画,父层动画运动期间,开始子层动画
start all views from current value, not initial value
UIViewAnimationOptionBeginFromCurrentState
执行动画后瞬间跳到初始状态继续无限次的执行同一动作
repeat animation indefinitely
UIViewAnimationOptionRepeat
反向执行一个动画,当动画执行完一遍后,沿原路径反向执行一遍.
if repeat, run animation back and forth
UIViewAnimationOptionAutoreverse
忽略继承自父层持续时间，使用自己持续时间（如果存在）
ignore nested duration
UIViewAnimationOptionOverrideInheritedDuration
忽略继承自父层的线性效果,使用自己的线性效果（如果存在）
ignore nested curve
UIViewAnimationOptionOverrideInheritedCurve
允许同一个view的多个动画同时进行
animate contents (applies to transitions only)
UIViewAnimationOptionAllowAnimatedContent
控制两个subview的显示示和隐藏(功能类似于addsubview和removefromsuperview),使用这个属性(一般在transitionFromView:toView:duration:options:completion:这个方法中使用),FromView会被隐藏toView会被显示
flip to/from hidden state instead of adding/removing
UIViewAnimationOptionShowHideTransitionViews
UIViewAnimationOptionCurveEaseInOut // default
UIViewAnimationOptionCurveEaseIn
UIViewAnimationOptionCurveEaseOut
UIViewAnimationOptionCurveLinear
UIViewAnimationOptionTransitionNone // default
UIViewAnimationOptionTransitionFlipFromLeft // 从左向右扭转翻页
UIViewAnimationOptionTransitionFlipFromRight // 从右向左扭转翻页
UIViewAnimationOptionTransitionCurlUp // 卷曲翻页，从下往上
UIViewAnimationOptionTransitionCurlDown // 卷曲翻页，从上往下
UIViewAnimationOptionTransitionCrossDissolve // 重叠，当一个view从一个位置到另一个位置时，当前的view会由透明状态逐渐到达显示到目的位置，原来的位置将会保留一个影子，并逐渐消失
UIViewAnimationOptionTransitionFlipFromTop // 从上向下扭转翻页
UIViewAnimationOptionTransitionFlipFromBottom // 从下向上扭转翻页
