ios - UISearchController的错位

Question

我的 UISearchController 有问题。我无法将它与 tableView 相关联地正确放置。

结果表没有覆盖主表的整个区域:

resultsTableController = ScuoleSearchResultsTableController()
resultsTableController.tableView.delegate = self
searchController = UISearchController(searchResultsController: resultsTableController)
searchController.searchResultsUpdater = self
searchController.searchBar.sizeToFit()
tableView.tableHeaderView = searchController.searchBar
searchController.delegate = self
searchController.dimsBackgroundDuringPresentation = true // default is YES
searchController.searchBar.delegate = self    // so we can monitor text changes + others
// Search is now just presenting a view controller. As such, normal view controller
// presentation semantics apply. Namely that presentation will walk up the view controller
// hierarchy until it finds the root view controller or one that defines a presentation context.
definesPresentationContext = true

Answer 1

信不信由你，我通过标记 UINavigationController 设置简单地解决了这个问题:

UINavigationBar.translucent = true
