ios - UIView.transition 显示具有深色背景的父视图(Swift)
问题描述
翻转时,父视图淡入黑色(从白色)到动画中间,然后再次淡入白色......为什么?
我的代码:
if !cardFrontView.isHidden {
let transitionOptions: UIViewAnimationOptions = [.transitionFlipFromRight, .showHideTransitionViews]
UIView.transition(from: cardFrontView, to: cardBackView, duration: 1.0, options: transitionOptions, completion: nil)
}
else {
let transitionOptions: UIViewAnimationOptions = [.transitionFlipFromLeft, .showHideTransitionViews]
UIView.transition(from: cardBackView, to: cardFrontView, duration: 1.0, options: transitionOptions, completion: nil)
}
我也试过UIView.transition(with:但我还有另一个问题:圆角正在消失。
整天为此苦苦挣扎......我的意思是这就是所有的代码。
解决方案
尝试将 BaseView Color 设置为UIColor.clear
instaed ofUIColor.white
