Question

在iOS12及更低版本上可以使用，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>>'

我该如何解决？这个例外是什么意思？

Answer 1

已解决。至少在beta 3中，您既不能在UISearchController中子类化UISearchBar。
