UISearchBar results not shown

Question

I'm using UISearchBar in my app.

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope 
{
    [self.filtered removeAllObjects];
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.companyName contains[cd] %@",searchText];
    NSArray *tempArray = [ee filteredArrayUsingPredicate:predicate];
    filtered = [NSMutableArray arrayWithArray:tempArray];
}

I did NSLog on above "filtered" array, it's getting proper search results.

I don't see the filtered values in the tableview. I see "No results" if I type wrong search text. But for the correct search text, the table view is plain empty.

Can anyone help me what needs to be done?

Thanks in advance!!

have you reload the tableview. Is Filtered array is datasouece of tableview ? — Vinodh, Jul 03 '13 at 05:06
My filtered Array is not null, I did NSLog to see the filtered values. I see the filtered array values in cellForRowAtIndexPath method as well and in numberOfRowsInSection. — user906492, Jul 03 '13 at 05:06
I have only one reload call inside viewDidLoad. I'm not sure what you mean by Filtered array is datasource? I didn't explicitly said it as datasource. Please let me know how to do it, if I've missed that. Thanks. — user906492, Jul 03 '13 at 05:14
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellId= @"eCell"; ECell *cell= [tableView dequeueReusableCellWithIdentifier:CellId]; if (cell==nil) { cell= [[ECell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } Ex *e; if (tableView== self.searchDisplayController.searchResultsTableView) { e= [filtered objectAtIndex:[indexPath row]]; } else { e= [ee objectAtIndex:indexPath.row]; } cell.company.text= e.companyName; return cell; } — user906492, Jul 03 '13 at 13:51
I've narrowed down the problem. If the cell is UITableViewCell, the Filter from SearchBar is working. I have a custom cell, in which I've extended the UITableViewCell to ECell. Using this, Filterdata is not working. Any idea? — user906492, Jul 03 '13 at 15:17
Hi user906492, did you solve this issue? I am also using a custom cell and getting empty results. — bashan, Aug 08 '13 at 18:47

Please use the following code . And make sure that self.filtered is the datasource of yourtableview . Datasource means array from tableview gets populated

 - (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope 
    {
        [self.filtered removeAllObjects];
        NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.companyName contains[cd] %@",searchText];
        NSArray *tempArray = [ee filteredArrayUsingPredicate:predicate];
        filtered = [NSMutableArray arrayWithArray:tempArray];
   [yourtableview reloadData];
    }
