一、大小动画（改变frame）
-(void)changeFrame{
CGRect originalRect = self.anView.frame;
CGRect rect = CGRectMake(self.anView.frame.origin.x-20, self.anView.frame.origin.y-120, 160, 80);
[UIView animateWithDuration:1 animations:^{
self.anView.frame = rect;
} completion:^(BOOL finished) {
[UIView animateWithDuration:1 animations:^{
self.anView.frame = originalRect;
}];
}];
}
二、拉伸动画（改变bounds）
-(void)changeBounds{
CGRect originalBounds = self.anView.bounds;
//尽管这个rect的x，y跟原始的不同，动画也只是改变了宽高
CGRect rect = CGRectMake(0, 0, 300, 120);
[UIView animateWithDuration:1 animations:^{
self.anView.bounds = rect;
} completion:^(BOOL finished) {
[UIView animateWithDuration:1 animations:^{
self.anView.bounds = originalBounds;
}];
}];
}
三、转移动画（改变center）
-(void)changeCenter{
CGPoint originalPoint = self.anView.center;
CGPoint point = CGPointMake(self.anView.center.x, self.anView.center.y-170);
[UIView animateWithDuration:0.3 animations:^{
self.anView.center = point;
} completion:^(BOOL finished) {
[UIView animateWithDuration:1 animations:^{
self.anView.center = originalPoint;
}];
}];
}
四、旋转动画(改变transform)
-(void)transform{
CGAffineTransform originalTransform = self.anView.transform;
[UIView animateWithDuration:2 animations:^{
//self.anView.transform = CGAffineTransformMakeScale(0.6, 0.6);//缩放
//self.anView.transform = CGAffineTransformMakeTranslation(60, -60);
self.anView.transform = CGAffineTransformMakeRotation(4.0f);
} completion:^(BOOL finished) {
[UIView animateWithDuration:2 animations:^{
self.anView.transform = originalTransform;
}];
}];
}
五、透明度动画(改变alpha)
-(void)alpha{
[UIView animateWithDuration:2 animations:^{
self.anView.alpha = 0.3;
} completion:^(BOOL finished) {
[UIView animateWithDuration:2 animations:^{
self.anView.alpha = 1;
}];
}];
}
六、背景颜色Keyframes动画（改变background）
-(void)changeBackground{
[UIView animateKeyframesWithDuration:9.0 delay:0.f options:UIViewKeyframeAnimationOptionCalculationModeLinear animations:^{
[UIView addKeyframeWithRelativeStartTime:0.f relativeDuration:1.0 / 4 animations:^{
self.anView.backgroundColor = [UIColor colorWithRed:0.9475 green:0.1921 blue:0.1746 alpha:1.0];
}];
[UIView addKeyframeWithRelativeStartTime:1.0 / 4 relativeDuration:1.0 / 4 animations:^{
self.anView.backgroundColor = [UIColor colorWithRed:0.1064 green:0.6052 blue:0.0334 alpha:1.0];
}];
[UIView addKeyframeWithRelativeStartTime:2.0 / 4 relativeDuration:1.0 / 4 animations:^{
self.anView.backgroundColor = [UIColor colorWithRed:0.1366 green:0.3017 blue:0.8411 alpha:1.0];
}];
[UIView addKeyframeWithRelativeStartTime:3.0 / 4 relativeDuration:1.0 / 4 animations:^{
self.anView.backgroundColor = [UIColor colorWithRed:0.619 green:0.037 blue:0.6719 alpha:1.0];
}];
[UIView addKeyframeWithRelativeStartTime:3.0 / 4 relativeDuration:1.0 / 4 animations:^{
self.anView.backgroundColor = [UIColor whiteColor];
}];
} completion:^(BOOL finished) {
NSLog(@"动画结束");
}];
}
七、Spring动画（iOS7.0起）
-(void)springAnimation{
CGRect originalRect = self.anView.frame;
CGRect rect = CGRectMake(self.anView.frame.origin.x-80, self.anView.frame.origin.y, 120, 120);
[UIView animateWithDuration:0.4 delay:0 usingSpringWithDamping:0.5 initialSpringVelocity:4 options:UIViewAnimationOptionCurveLinear animations:^{
self.anView.frame = rect;
} completion:^(BOOL finished) {
[UIView animateWithDuration:1 delay:1 usingSpringWithDamping:0.5 initialSpringVelocity:4 options:UIViewAnimationOptionCurveLinear animations:^{
self.anView.frame = originalRect;
} completion:^(BOOL finished) {
}];
}];
}
八、transition动画
-(void)transitionAnimation{
[UIView transitionWithView:self.anView duration:2.0 options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{
//self.anView.backgroundColor = [UIColor blueColor];
} completion:^(BOOL finished) {
[UIView transitionWithView:self.anView duration:2.0 options:UIViewAnimationOptionTransitionFlipFromRight animations:^{
//self.anView.backgroundColor = [UIColor greenColor];
} completion:^(BOOL finished) {
}];
}];
}
九、关于参数option选择说明
1.UIViewAnimationOptions
UIViewAnimationOptionLayoutSubviews //进行动画时布局子控件
UIViewAnimationOptionAllowUserInteraction //进行动画时允许用户交互
UIViewAnimationOptionBeginFromCurrentState //从当前状态开始动画
UIViewAnimationOptionRepeat //无限重复执行动画
UIViewAnimationOptionAutoreverse //执行动画回路
UIViewAnimationOptionOverrideInheritedDuration //忽略嵌套动画的执行时间设置
UIViewAnimationOptionOverrideInheritedCurve //忽略嵌套动画的曲线设置
UIViewAnimationOptionAllowAnimatedContent //转场：进行动画时重绘视图
UIViewAnimationOptionShowHideTransitionViews //转场：移除（添加和移除图层的）动画效果
UIViewAnimationOptionOverrideInheritedOptions //不继承父动画设置
UIViewAnimationOptionCurveEaseInOut //时间曲线，慢进慢出（默认值）
UIViewAnimationOptionCurveEaseIn //时间曲线，慢进
UIViewAnimationOptionCurveEaseOut //时间曲线，慢出
UIViewAnimationOptionCurveLinear //时间曲线，匀速
UIViewAnimationOptionTransitionNone //转场，不使用动画
UIViewAnimationOptionTransitionFlipFromLeft //转场，从左向右旋转翻页
UIViewAnimationOptionTransitionFlipFromRight //转场，从右向左旋转翻页
UIViewAnimationOptionTransitionCurlUp //转场，下往上卷曲翻页
UIViewAnimationOptionTransitionCurlDown //转场，从上往下卷曲翻页
UIViewAnimationOptionTransitionCrossDissolve //转场，交叉消失和出现
UIViewAnimationOptionTransitionFlipFromTop //转场，从上向下旋转翻页
UIViewAnimationOptionTransitionFlipFromBottom //转场，从下向上旋转翻页
2.UIViewKeyframeAnimationOptions
UIViewAnimationOptionLayoutSubviews //进行动画时布局子控件
UIViewAnimationOptionAllowUserInteraction //进行动画时允许用户交互
UIViewAnimationOptionBeginFromCurrentState //从当前状态开始动画
UIViewAnimationOptionRepeat //无限重复执行动画
UIViewAnimationOptionAutoreverse //执行动画回路
UIViewAnimationOptionOverrideInheritedDuration //忽略嵌套动画的执行时间设置
UIViewAnimationOptionOverrideInheritedOptions //不继承父动画设置
UIViewKeyframeAnimationOptionCalculationModeLinear //运算模式 :连续
UIViewKeyframeAnimationOptionCalculationModeDiscrete //运算模式 :离散
UIViewKeyframeAnimationOptionCalculationModePaced //运算模式 :均匀执行
UIViewKeyframeAnimationOptionCalculationModeCubic //运算模式 :平滑
UIViewKeyframeAnimationOptionCalculationModeCubicPaced //运算模式 :平滑均匀
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iOS7.0以上才有
4.UIViewKeyframeAnimationOptions用着Keyframes动画，其余都用UIViewAnimationOptions枚举
