ios - 推送时从UISearchController删除搜索栏

Question

我有一个搜索栏图标，一旦按下它就会调用它:

SearchTableViewController *searchView = [[SearchTableViewController alloc]initWithNibName:@"SearchTableViewController" bundle:nil];
UINavigationController *navCtlr = [[UINavigationController alloc]initWithRootViewController:searchView];
UISearchController *searchController = [[UISearchController alloc]initWithSearchResultsController:navCtlr];
[searchController setDefinesPresentationContext:YES];
searchController.delegate = searchView;
searchController.searchResultsUpdater = searchView;
searchView.searchController = searchController;
searchController.searchBar.keyboardAppearance = UIKeyboardAppearanceDark;
[self presentViewController:searchController animated:YES completion:nil];

在我的SearchTableViewController.m文件中，我有一个成功调用的推送命令:

 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
 DetailTableViewController *seeAll = (DetailTableViewController *) [storyboard instantiateViewControllerWithIdentifier:@"DetailTableViewController"];
 seeAll.query = self.searchController.searchBar.text;
 seeAll.title = @"Songs";
 [self.navigationController pushViewController:seeAll animated:YES];

但是，我没有得到预期的行为，即。

预期基于Apple Music的UISearchController:
推送之前:


推送后:


对我来说，发生了什么事:

推送前后是一样的:
