Unable to keep Table row is selected

Question

In my app, I used a splitView. There are 3 different tables.

When I select any row from 1st Table, the display in the detail view & row remains selected in Left side menu. However, when I select any row from 2nd or 3rd Table, the row is just highlighted with blue color & quickly disappear the Selected blue (i.e. it does not remain Highlighted).

Help me solve this problem.

My code as follow:

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


    static NSString *CellIdentifier=@"CellIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

    if (cell == nil) {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    if(tableView == tbl_class)
    {

         btnEdit1 = [UIButton buttonWithType:UIButtonTypeCustom];
        [btnEdit1 setFrame:CGRectMake(220, 15, 20, 20)];
        [btnEdit1 addTarget:self action:@selector(btnEditPressed:) forControlEvents:UIControlEventTouchUpInside];

        [btnEdit1 setImage:[UIImage imageNamed:@"edit-3-black.png"]                   forState:UIControlStateNormal];

        UIButton *btnDelete = [UIButton buttonWithType:UIButtonTypeCustom];
        [btnDelete setFrame:CGRectMake(260, 15, 20, 20)];
        [btnDelete addTarget:self action:@selector(btnDelete:) forControlEvents:UIControlEventTouchUpInside];

        [btnDelete setImage:[UIImage imageNamed:@"recycle-bin2.png"]                   forState:UIControlStateNormal];

        [btnEdit1 setTag:indexPath.row];
        [btnDelete setTag:indexPath.row];

        cell.textLabel.text=[NSString stringWithFormat:@"%@",[[classNames objectAtIndex:indexPath.row]valueForKey:@"class_name"]];

        if(! isEditing)
        {
            [cell.contentView addSubview:btnEdit1];
            [cell.contentView addSubview:btnDelete];
        }



     }
     if(tableView==tbl_assessment)
    {
        if (classNames.count > 0)
        {
            [btnAddAssesst setHidden:NO];
        }
        else
        {
            [btnAddAssesst setHidden:YES];
        }



       cell.textLabel.text=[NSString stringWithFormat:@"%@",[[assessment_list objectAtIndex:indexPath.row]valueForKey:@"assessment_name"]];

    }

    if (tableView==tbl3)
    {

        cell.textLabel.text=[arr_result objectAtIndex:indexPath.row];

    }

    cell.textLabel.font=[UIFont fontWithName:@"Trebuchet MS" size:17.0f];


    cell.textLabel.textColor=[UIColor grayColor];

    return cell;
}

Two things to do to keep the row as selected

• -deselectRowAtIndexpath should not be there in didselectRowAtIndexpath
• Keep an NSMutableArray of NSIndexpath for storing the selected value .When a row is selected add it to array and in the -cellForRowAtIndexpath method check the indexpath is there in cell and if it is there make [tablecell setSelected:YES]; otherwise NO
