Two bugs I remember:
1. Tapping on top of the screen usually scrolls the table view back to the top.
This did not happen when a filtered list was displayed.
2. Rotating the phone messed up the position of the search field.

When I used UISearchController I created it in my subclass of
UITableViewController:
- (void)viewDidLoad
{
[super viewDidLoad];
ResultsTableController *resultsController = [[ResultsTableController
alloc] init];//UITableViewController
resultsController.tableView.delegate = self; //
default = resultsController
UISearchController *searchCntr = [[UISearchController alloc]
initWithSearchResultsController: resultsController];
searchCntr.delegate = self;
// UISearchControllerDelegate
searchCntr.searchResultsUpdater = self;
// UISearchResultsUpdating
searchCntr.dimsBackgroundDuringPresentation = NO; //
default is YES
self.searchController = searchCntr;
UISearchBar *searchBar = searchCntr.searchBar;
searchBar.delegate = self;
// UISearchBarDelegate
searchBar.scopeButtonTitles = @[ @"Starts", @"Contains", @"Content" ];
self.tableView.tableHeaderView = searchBar;
self.definesPresentationContext = YES;
}
