1 Position 平移

[UIView animateWithDuration:1.0 animations:^{

_blueView.centerX = self.view.width -100;    _blueView.centerY = self.view.height -150;}];

2 Opacity 透明度

(void)viewDidLoad {

[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
_redView = [[UIView alloc]init];
_redView.backgroundColor = [UIColor redColor];
_redView.left = 100;
_redView.top = 100;
_redView.height = 100;
_redView.width = 100;
[self.view addSubview:_redView];
}

-(void)touchesBegan:(NSSet<UITouch > )touches withEvent:(UIEvent *)event {

[UIView animateWithDuration:1.0 animations:^{    _redView.alpha = 0.3;}];

}

3 Scale 尺寸

[UIView animateWithDuration:1.0 animations:^{    _yellowView.transform = CGAffineTransformMakeScale(0.3, 0.3);}];

4 Ratation 偏移

[UIView animateWithDuration:1.0 delay:0 options:UIViewAnimationOptionRepeat animations:^{

_grayView.transform = CGAffineTransformRotate(_grayView.transform, M_PI);} completion:nil];[UIView animateWithDuration:1.0 delay:0 options:UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse animations:^{    _blackView.left = self.view.width -_blackView.width -50;} completion:nil];

UIViewAnimationOption

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
