Area:
UIKit

Summary:
For a standard setup, with the searchbar in the navigation bar, and the search results in a UITableViewController, a small gap shows between the top of the search results and the search bar in portrait orientation. In landscape orientation the opposite is true: the searchbar partly overlaps the search results.

Steps to Reproduce:
1) Run the attached project which sets up the UISearchController in the following manner:

- (void) viewDidLoad
{
    [super viewDidLoad];
    
    SearchResults *searchResults = [[SearchResults alloc] init];
    searchController = [[UISearchController alloc] initWithSearchResultsController:searchResults];
    searchController.searchResultsUpdater = searchResults;
    
    self.navigationItem.titleView = searchController.searchBar;

    searchController.hidesNavigationBarDuringPresentation = NO;
    searchController.dimsBackgroundDuringPresentation = YES;
    self.definesPresentationContext = YES;
}

2) Tap on the search bar and enter some text

Expected Results:
The search results to show directly under the searchbar

Actual Results:
In portrait mode: a gap appears between searchbar and search results
In landscape mode: the searchbar overlaps the search results

Version:
iOS 10.0
