【问题描述】：

在 ios12 及更低版本上工作，但在 iOS13 上崩溃并出现此错误

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'UISearchController's control over its search bar has been destroyed. Please use the search bar provided by the UISearchController. searchController = <AdvancedSearchController: 0x7fbd9d224a00>, searchBar = <TDSearchBar: 0x7fbd9b768480; baseClass = UISearchBar; frame = (0 0; 1024 50); text = ''; gestureRecognizers = <NSArray: 0x600002791770>; layer = <CALayer: 0x600002ef9be0>>'

我如何解决？这个异常是什么意思？

【参考方案1】：

解决了。你不能在 UISearchController 中继承 UISearchBar...至少在 beta 3 中。

【讨论】：

我想知道您是否再次尝试使用 iOS 13/13.1 发行版？我打算自己写一个自定义的UISearchBar 子类，直到我看到这个问题/答案。谢谢！

回答我自己的评论：我可以在 iOS 13.0 和 13.1 中继承 UISearchBar 和 UISearchController
