我已经实现了UISearchController,它工作得很好,除了......

当我单击搜索栏时,导航栏会按预期消失.当我将手机旋转到横向视图时,我得到了这个有意义的视图.

但是,当我将手机旋转回纵向视图(仍然在搜索类型区域中选择)时,我得到以下视图.

您可以看到导航栏永远不会再出现.我觉得我正在实现一个基本的搜索控制器.什么可能导致这个？

self.venueSearchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.venueSearchController.searchResultsUpdater = self;
self.venueSearchController.searchBar.delegate = self;
self.venueSearchController.dimsBackgroundDuringPresentation = NO;
self.venueSearchController.hidesNavigationBarDuringPresentation = YES;
self.venueSearchController.searchBar.frame = CGRectMake(self.venueSearchController.searchBar.frame.origin.x, self.venueSearchController.searchBar.frame.origin.y, self.venueSearchController.searchBar.frame.size.width, 44.0);

self.definesPresentationContext = YES;

self.navigationController.navigationBar.translucent = YES;
self.venueSearchController.searchBar.translucent = YES;

self.tableView.tableHeaderView = self.venueSearchController.searchBar;

空白仅出现在iOS 10上。
