UIView动画补充
我自己的总结:
// 第一种: Duration 时间 animations:动画体
/*
[UIView animateWithDuration:4 animations:^{
CGRect rect = redView.frame;
rect.origin.y += 25;
redView.frame = rect;
}];
*/
// 第二种: Duration 时间 animations:动画体 动画优点卡顿 相比第一种动画结束增加了一个回调
/*
[UIView animateWithDuration:4 animations:^{
CGRect rect = redView.frame;
rect.origin.y += 25;
redView.frame = rect;
} completion:^(BOOL finished) {
//动画结束
CGRect rect = redView.frame;
rect.origin.y -= 25;
redView.frame = rect;
}];
*/
//第三种:相比前两种增加一个延时,
/*
[UIView animateWithDuration:2 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
CGRect rect = redView.frame;
rect.origin.y += 100;
redView.frame = rect;
} completion:^(BOOL finished) {
}];
*/
//第四种: 弹簧效果动画
//usingSpringWithDamping:弹簧动画的阻尼值,也就是相当于摩擦力的大小,该属性的值从0.0到1.0之间,越靠近0,阻尼越小,弹动的幅度越大,反之阻尼越大,弹动的幅度越小,如果大道一定程度,会出现弹不动的情况。
// initialSpringVelocity:弹簧动画的速率,或者说是动力。值越小弹簧的动力越小,弹簧拉伸的幅度越小,反之动力越大,弹簧拉伸的幅度越大。这里需要注意的是,如果设置为0,表示忽略该属性,由动画持续时间和阻尼计算动画的效果。
/*
[UIView animateWithDuration:2 delay:0 usingSpringWithDamping:0.1 initialSpringVelocity:0.5 options:UIViewAnimationOptionCurveLinear animations:^{
CGRect rect = redView.frame;
rect.origin.y += 100;
redView.frame = rect;
} completion:^(BOOL finished) {
}];
*/
/**
UIViewAnimationOptionTransitionNone = 0 << 20, // default
UIViewAnimationOptionTransitionFlipFromLeft = 1 << 20,
UIViewAnimationOptionTransitionFlipFromRight = 2 << 20,
UIViewAnimationOptionTransitionCurlUp = 3 << 20,
UIViewAnimationOptionTransitionCurlDown = 4 << 20,
UIViewAnimationOptionTransitionCrossDissolve = 5 << 20,
UIViewAnimationOptionTransitionFlipFromTop = 6 << 20,
UIViewAnimationOptionTransitionFlipFromBottom = 7 << 20,
*/
//第五种: 翻页,旋转
/*
[UIView transitionWithView:redView duration:2 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
} completion:^(BOOL finished) {
}];
*/
//第六种: 页面反动
/*
[UIView transitionFromView:blueView toView:redView duration:5 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) {
[UIView transitionFromView:redView toView:blueView duration:5 options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) {
}];
}];
*/
//第六种: 页面反动,系统动画performSystemAnimation只有一种删除动画,不知道为什么
/*
[UIView performSystemAnimation:UISystemAnimationDelete onViews:@[redView] options:UIViewAnimationOptionTransitionNone animations:^{
} completion:^(BOOL finished) {
}];
*/
[UIView animateKeyframesWithDuration:5 delay:0 options:UIViewKeyframeAnimationOptionAutoreverse animations:^{
[UIView addKeyframeWithRelativeStartTime:0 relativeDuration:1 animations:^{
CGRect rect = redView.frame;
rect.origin.y += 500;
redView.frame = rect;
}];
[UIView addKeyframeWithRelativeStartTime:1 relativeDuration:3 animations:^{
CGRect rect = redView.frame;
rect.origin.y -= 700;
redView.frame = rect;
}];
[UIView addKeyframeWithRelativeStartTime:3 relativeDuration:5 animations:^{
CGRect rect = redView.frame;
rect.origin.y += 1000;
redView.frame = rect;
}];
} completion:^(BOOL finished) {
}];

谢谢二爷的示范,经典的表情也勾起很多人的回忆。好,我们回到现实,以上的3个例子,大家不难发现共同的特点和重复性。
1.都是改变UIView的属性就可以产生动画
2.都是带有block做结束回调,对结束监控
3.动画大小和位置变化可以通过多种方式实现
“佛爷,是不是很好奇我们并没有使用Tom先生很多图片组逐一显示?来,也请您下矿一走!”。“哈哈,好!不过那碗河水我还是要倒的”,“行,随你翻腾~”。

卓先生,停停停,来,回到我们舞台中间来。就以上5中都能让您玩的这么愉快,以上都是仅仅修改本身的属性值,我再介绍剩下三种基于UIView特别的动画,一个是Keyframe,一个Spring和Transition动画。一人一个轮着来,卓先生你先。

就UIView的动画而言,UIViewKeyframeAnimationOptions紧在Keyframes,其余的都是UIViewAnimationOptions。
十.总结和扩展
1.UIView动画主要是变化UIView的自带属性
2.UIView动画可以有很多种方式实现同一效果
3.Spring动画iOS 7.0以上才有
4.UIViewKeyframeAnimationOptions用着Keyframes动画,其余都用UIViewAnimationOptions枚举
