Set the Transform property of the View object to achieve a variety of animation effects.
1, moveIn the same plane, the control translates a certain distance in a straight line direction.

//每次都从当前位置平移self.imageView.transform = CGAffineTransformTranslate(self.imageView.transform, -2.1, -2.1)//每次都从最开始的位置计算平移self.imageView.transform = CGAffineTransformMakeTranslation(2.3, 2.3) |
2, rotate

//连续旋转UIView.beginAnimations(nil, context: nil)UIView.setAnimationDuration(3.0) //设置动画时间self.imageView.transform = CGAffineTransformRotate(self.imageView.transform, CGFloat(-M_PI/2))UIView.commitAnimations()//独立旋转，以初始位置旋转self.imageView.transform = CGAffineTransformMakeRotation(CGFloat(-M_PI/4)) |
