###1.平移，缩放，旋转

//平移self.tempView.transform = CGAffineTransformMakeTranslation(-100, 100);//缩放self.tempView.transform = CGAffineTransformMakeScale(0.5, 0.5);//旋转self.tempView.transform = CGAffineTransformMakeRotation(-M_PI_4);

###2.除此之外还可以叠加动画效果，三种或者两种合起来

//平移+缩放+旋转CGAffineTransform translation = CGAffineTransformMakeTranslation(-100, 100);CGAffineTransform scaleTranslation = CGAffineTransformScale(translation, 0.5, 0.5);CGAffineTransform rotateScaleTranslation = CGAffineTransformRotate(scaleTranslation, M_PI_2); self.tempView.transform = rotateScaleTranslation;

###3.清空以前的效果，在回复原来的时候也可以做动画，跟之前相反的效果

// 清空transform，以前的平移、缩放、旋转都会消失[UIView animateWithDuration:2.0 animations:^{        self.tempView.transform = CGAffineTransformIdentity;        }];
