UIStackViews 在另一个 UIStackView 和 TableView 中折叠

Question

对此很陌生，非常感谢您提供的所有帮助。

我花了很多时间浏览网络并尝试不同的解决方案，但我不知所措。

我正在使用 tableView 在视图中填充事件。这些事件可以有多个参与者 (2 - 8) 参与者（和其他对象）由子堆栈视图表示，我根据参与者数组的数量控制是否显示 stackView7、stackView8 等。

出于某种原因，有时一个或几个参与者堆栈视图被压缩到更小的尺寸。

很抱歉附加了太多代码，但我真的不确定哪些是相关的。

提前谢谢你，如果上下文需要不同的代码，请告诉我
