xcode search bar crash try to enter something

Question

enter image description here

#pragma Search Methods

-(void)filterContentForSearchText:(NSString *)searchText scope:(NSString *)scope
{
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF beginswith[c] %@",searchText];
    _AramaSonuclari = [_TarifAdi filteredArrayUsingPredicate:predicate];
    
}

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
    [self filterContentForSearchText:searchString scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
    return YES;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    
    // Return the number of rows in the section.
    if (tableView == self.searchDisplayController.searchResultsTableView)
    {
        return [_AramaSonuclari count];
    }
    else
    {
        return _TarifAdi.count;
    }
    
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    
    TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"TableViewCell" forIndexPath:indexPath];
    
    cell.tag = indexPath.row;
    //cell.imageView.image = nil;
    
    if (tableView == self.searchDisplayController.searchResultsTableView)
    {
        cell.TitleLabel.text = _AramaSonuclari[indexPath.row];
    }
    else
    {
        cell.TitleLabel.text = _TarifAdi[indexPath.row];
    }

    return cell;
 }

Our problem, when we try to enter any character in the search bar, app crashes, we did debug our code work without error. We think, our problem is on storyboard connection; also I added an image. When we delete searchBar referencing outlets, we can type something but of course the code is not working without connection.

Error Log:

2014-07-14 13:29:08.577 SevgiLezzeti[3839:60b] *** Assertion failure in -[UISearchResultsTableView dequeueReusableCellWithIdentifier:forIndexPath:], /SourceCache/UIKit_Sim/UIKit-2935.137/UITableView.m:5439

Yes i defined my code work without search when i try to searchBar still no problem but when i try to type something instant crash — Gökhan Çokkeçeci, Jul 14 '14 at 10:39
try using self.tableView when dequeueing the cell instead of tableView since tableView may not be the instance of the one where the cell id has been defined — giorashc, Jul 14 '14 at 10:47

You have to register the cell to searchdisplaycontroller as well.

Important: You must register a class or nib file using the registerNib:forCellReuseIdentifier: or registerClass:forCellReuseIdentifier: method before calling this method.

in View did load

If you are Creating cell in code

 [self.searchDisplayController.searchResultsTableView registerClass:[TableViewCell class] 
    forCellReuseIdentifier:@"IdentifierForCell"];

If you are Creating cell in nib

  [self.searchDisplayController.searchResultsTableView registerNib:[UINib nibWithNibName:@"CellNibName" bundle:nil]
                                        forCellWithReuseIdentifier:@"IdentifierForCell"];

Now we can not see result how we can fix this problem ? – Gökhan Çokkeçeci Jul 14 '14 at 11:22 — Gökhan Çokkeçeci, Jul 14 '14 at 11:22
check NSPredicate. whether gives the data or not – Vijay-Apple-Dev.blogspot.com Jul 14 '14 at 11:23 — Vijay-Apple-Dev.blogspot.com, Jul 14 '14 at 11:23

I solved it like that :

at this line :

TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"TableViewCell" forIndexPath:indexPath];

you need to delete "forIndexPath:indexPath" so:

 TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"TableViewCell"];

This solved the problem in the op but then I got "fatal error: unexpectedly found nil while unwrapping an Optional value" – Danny Wang Mar 18 '16 at 03:40

You are using in swift, u should check if one of the fields isn't nil. http://stackoverflow.com/questions/24643522/fatal-error-unexpectedly-found-nil-while-unwrapping-an-optional-values – Almog_0 Mar 19 '16 at 15:11
