How to use one UIStoryboard scene with UITableViewController and resultsTableViewController in concert with UISearchController?

Question

With iOS 8, UISearchDisplayController was deprecated, leaving UISearchController the option for adding search behavior to the applications. This forces the developers to create a separate UITableviewController to display the search results – lets call this tableViewController for resultsTableViewController. How to migrate from UISearchDisplayController to UISearchController is well covered in this thread: searchDisplayController deprecated in iOS 8

In my applications, I am using interfacebuilder and storyboard. My UITableViewController is customized in the storyboard, with custom cells, giving me what i want. However, I want my resultsTableViewController to look exactly like my tableViewController.

Question: Is there a way to use the same scene in the storyboard for both my tableViewController and resultsTableViewController? If not, what is the best workaround? This question is partly answered here: How to share one storyboard scene between multiple UIViewControllers, but I still have a way to go.

To avoid the problem, could you set resultsTableViewController to nil, and instead apply the filter to the main the tableView? — pbasdf, Jan 03 '15 at 22:44
Great. Haven't seen `filteredWithPattern:` before - is it defined in a category of NSArray? — pbasdf, Jan 04 '15 at 14:11

With help from tartempion in the Apple developer forum, I finally managed a UTableviewController and searchViewController in one file, enabling me to use the same storyboard scene to display search results.

@interface TableViewController () <UISearchBarDelegate, UISearchControllerDelegate, UISearchResultsUpdating>
{
    UISearchController *_searchcontroller;

     NSArray * myArray;
     NSArray * myDisplayedArray; 
}
@end

@implementation TableViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    [...]

     _searchcontroller=[[UISearchController alloc]initWithSearchResultsController:nil];
     _searchcontroller.searchResultsUpdater =self;
     _searchcontroller.dimsBackgroundDuringPresentation=NO;

     myDisplayedArray=myArray;
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return [myDisplayedArray count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    MyClass*myInstance =[myDisplayedArray objectAtIndex:[indexPath row]];

  //and however you want to configure cells...

}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

  //whatever you need...
  //and to get rid of the searchcontroller when you move to the UIView that is connected
        self.searchcontroller.active=NO;
                 //or
        [self.searchcontroller dismissViewControllerAnimated:NO completion:nil];

}

#pragma mark -

- (void)updateSearchResultsForSearchController:(UISearchController *)inSearchController
{
    if (_searchController==inSearchController)
    {
        NSString *tSearchText = inSearchController.searchBar.text;

        if ([tSearchText length]==0)
        {
            myDisplayedArray=myArray;
        }
        else
        {
            myDisplayedArray=[myArray filteredWithPattern:tSearchText];
        }

        [self.tableView reloadData];
    }
}

@end
