swift - UISearchController 模式呈现样式错误

Question

我以编程方式将 UISearchController 添加到 UIStackView，它作为 subview 嵌入到更大的 View 中，我将其添加到 UITableViewController 中的 UITableViewCell。

我将 UITableViewController 设置为搜索栏委托(delegate)、更新程序委托(delegate)和搜索 Controller 委托(delegate)。

但是，当我将 UISearchController 添加到 View 时，出现此错误:

UISearchController only supports modal presentation styles UIModalPresentationPopover, UIModalPresentationFormSheet and UIModalPresentationCustom

然后，当我稍微尝试一下并设置此设置时:

searchController.modalPresentationStyle = .popover

然后我收到此错误:

Presenting UISearchController in a popover or form sheet while reusing the search origin as the search results destination makes little sense. Initialize UISearchController with a proper search results controller to present as a popover or in a form sheet

这些错误意味着什么？

Answer 1

改变

let searchController = UISearchController()

至

let searchController = UISearchController(searchResultsController: myViewController)

为我解决了 myViewController 继承自 UIViewController 的问题。
