我在向上滑动时使用卷曲动画,这使得卡片飞到顶部 - 它工作正常。我想使用相同的动画,但要向下滑动,以便卡片飞走。我想我必须以某种方式将动画向上滑动180度。这可能吗?
let views = (frontView: self.frontView, backView: self.frontView)
// set a transition style
let transitionOptions = UIViewAnimationOptions.TransitionCurlUp
UIView.transitionWithView(self.flashCardView, duration: 0.5, options: transitionOptions, animations: {
views.frontView.removeFromSuperview()
self.flashCardView.addSubview(views.frontView)
}, completion: { finished in
// any code entered here will be applied
})
答案 0 :(得分:0)
UIViewAnimationOptions结构有另一个选项可以解决这个问题:
let transitionOptions = UIViewAnimationOptions.TransitionCurlDown
