iOS内容通过动画从水平到垂直，反之亦然
我们能否通过iOS内容通过动画从水平到垂直，反之亦然,ios,swift,uistackview,Ios,Swift,Uistackview,我们能否通过UIStackView实现这一点，因为最初它的垂直轴，然后最终它将是水平轴，反之亦然 如果使用NSAutoLayout，如何做到这一点 需要帮助，如果有人可以提供我的例子来源或任何提示在这里将是有益的 更新答案 多亏了@Fogmeister 首先，我做两个堆栈视图 一个保持命名和配置文件图像 和bigStackView保持第一个stackView和后续按钮 像这样的约束 BigStackView: 我之所以在左、右各加20分，是因为如果我将其设为0，则“跟随”按钮将接近屏幕边缘

我希望这个解决方案对您来说是常见的我想我应该使用
UIStackViewUIView.animate(withDuration: 0.5) {
stackView.axis = .horizontal
roundViewHeightConstraint.constant = 60
roundView.layer.cornerRadius = 30
}
stackView.axis = .horizontal
roundViewHeightConstraint.constant = 60
UIView.animate(withDuration: 0.5) {
containerView.layoutIfNeeded()
}
角半径不能在层上正确设置动画。这是因为我使用的是UIView，而不是像您原来使用的UIImageView。使用UIImageView，您不会像我这样费心更改角半径。只需使用圆形图像即可。我想我应该使用
UIStackViewUIView.animate(withDuration: 0.5) {
stackView.axis = .horizontal
