UIViewAnimationOptionTransitionCurlUp start from left bottom corner

Question

I try to use method [UIView transitionFromView:toView:duration:options:completion:]; for change some images and hide some elements with UIViewAnimationOptionTransitionCurlUp (and UIViewAnimationOptionTransitionCurlDown in the reverse situation). It works, but I would like to start flipping from the bottom left corner.

Does anyone know a solution?

尝试将容器视图（已应用过渡的视图）的transform设置为CGAffineTransformMakeScale(-1,1)以翻转过渡效果，并在其内容视图上应用相同的transform以翻转内容。
