ios - 遇到奇怪的错误 : "DOMException 105" in IOS app. 正在寻找有关如何在我的代码中定位错误的指导

Question

无法在任何地方找到对此错误的任何引用!

它每次都在同一点发生——就像我点击一个 UITableView 行元素一样。下面是堆栈跟踪 - 有人可以就问题可能是什么和/或如何找到错误提供任何建议吗？

谢谢!

Answer 1

自从过去 2 天以来，我在寻找解决方案时遇到了同样的问题。今天终于找到了解决方案，要么需要在 viewDidLoad 中添加 self.view.isAccessibilityElement = true，要么在界面中设置 View 的 Attribute 属性，如下图所示。
