uiview翻转动画轴心问题
我在view1的背面加上view2，view1翻转过来就显示view2，利用uiview动画UIViewAnimationOptionTransitionFlipFromRight实现。
问题是view1翻转的时候不是按照view1的中间轴心翻转，而是按self。view的轴心翻转，请问怎么解决这个问题？
[self.view1 sendSubviewToBack:self.view2]
[UIView transitionFromView:(self.view1)
toView:(self.view2)
duration: 2
options: UIViewAnimationOptionTransitionFlipFromLeft+UIViewAnimationOptionCurveEaseInOut
completion:^(BOOL finished) {
if (finished) {
}
}];
