CGAffineTransform函数旋转操作

首先获取UITableView的CGAffineTransform函数：
CGAffineTransform transform=self.mytableview.transform;
对获取的CGAffineTransform函数进行旋转，旋转角度为逆时针旋转90度：
    transform=CGAffineTransformRotate(transform, -M_PI/2.0);
将新获取的CGAffineTransform函数赋给UITableView，即可旋转：
    self.mytableview.transform=transform;

 

3D旋转

 

//set default transform

            CATransform3D transform = CATransform3DMakeTranslation(0.0f, 0.0f, -15.0f);

            transform = CATransform3DRotate(transform, (CGFloat)M_PI + 0.4f, 0.0f, 0.0f, 1.0f);

            transform = CATransform3DRotate(transform, (CGFloat)M_PI_4, 1.0f, 0.0f, 0.0f);

            transform = CATransform3DRotate(transform, -0.4f, 0.0f, 1.0f, 0.0f);

            transform = CATransform3DScale(transform, 3.0f, 3.0f, 3.0f);

            self.modelView.modelTransform = transform;
