ios - iOS 垂直居中搜索 Controller

Question

我用代码以编程方式添加了 UISearchController

 let searchController = UISearchController(searchResultsController: nil)

 override func viewDidLoad() {
    super.viewDidLoad()

    searchController.searchResultsUpdater = self
    searchController.obscuresBackgroundDuringPresentation = false
    searchController.searchBar.placeholder = "Введіть значення для пошуку"
    searchController.searchBar.backgroundColor = .white
    navigationItem.searchController = searchController
    definesPresentationContext = true

}

但是好像没有垂直居中。我该如何修复它？

Answer 1

将 SearchController 连接到 TableView 而不是 NavigationItem

tableView.tableHeaderView = searchController.searchBar
