我的 UI 有一个 UITableView 和另一个 View 。 UITableView 具有可折叠部分,如 sample code 所示。 。加载后看起来像这样:
用户可以使用滑动手势来展开右侧的灰色 View 。我只是改变灰色 View 的原点并使用动画来实现这一点。那么它看起来像这样:
但是,当我关闭 UITableView 的一部分时,UI 似乎会“重置”并恢复到其原始布局:
当我打开或关闭 UITableView 的一部分时,我希望灰色 View 保持在原来的位置。我怎样才能做到这一点?

最佳答案
这是由于自动布局造成的。如果在打开自动布局的情况下直接更改任何框架,则一旦 View 必须更新自身, View 将恢复到由其约束定义的位置。您应该通过为您想要更改的任何约束创建 IBOutlet 来完成动画,并在代码中调整它们的常量值(或者关闭自动布局)。
