方法一：头尾式动画

- (IBAction)moveClick:(UIButton *) sender

{

CGPoint center = self.head.center;

switch (sender.tag)

{

case 1:

center.y -= 10;

break;

case 2:

center.x += 10;

break;

case 3:

center.y += 10;

break;

case 4:

center.x -= 10;

break;

default:

break;

}

[UIView beginAnimations:nil context:nil];

[UIView setAnimationDuration:1];

self.head.center = center;

[UIView commitAnimations];

}

方法二：通过block实现动画

- (IBAction)moveClick:(UIButton *) sender

{

CGPoint center = self.head.center;

switch (sender.tag)

{

case 1:

center.y -= 10;

break;

case 2:

center.x += 10;

break;

case 3:

center.y += 10;

break;

case 4:

center.x -= 10;

break;

default:

break;

}

[UIView animateWithDuration:1 animations:^{self.head.center = center;}];

}

总结：

self.head.transform = CGAffineTransformTranslate(self.head.transform, 0, 20);//平移

self.head.transform = CGAffineTransformScale(self.head.transform, 1.2, 1.2);//缩放

self.head.transform = CGAffineTransformRotate(self.head.transform, -M_PI_4);//旋转
