How to display different element from different array in different section in single table view?

Question

I have a table with 3 sections, all three sections have different number of rows. The cell values should populate from different array's. So how should i find out which section is it in method cellForRowAtIndexPath:???

Please help!!!

Code:

- (NSInteger)tableView:(UITableView *)tv numberOfRowsInSection:(NSInteger)section
{
    currentSection = section;
    int number = 0;
    switch (section) {
        case 0:
            number = self.basic.count;
            break;
        case 1:
            number = allSectors.count;
            break;
        case 2:
            number = 1;
            break;
        default:
            number = 0;
            break;
    }

    return number;
}

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tv dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier]autorelease];

    }
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    CGFloat fontSize = [UIFont systemFontSize];
    CGFloat smallFontSize = [UIFont smallSystemFontSize];
    switch (indexPath.section) {
    case 0:
        cell.textLabel.text = [self.basic objectAtIndex:indexPath.row];
        break;
    case 1:
        cell.textLabel.text = [self.allSectors objectAtIndex:indexPath.row];
        break;
    case 2:
        cell.textLabel.text = @"None";
        break;

    default:
        break;
}


return cell;
}

Just use indexPath.section to get the table section, and indexPath.row to get the row in that section. These properties are defined in the category NSIndexPath (UIKitAdditions).

ok cool. I used this and i suppose its working but when i am trying to scroll down and see what's get displayed in the next section , it crashes. Is there any thing wrong i am doing. Please see above for code.

@Ashutosh, I don't see anything that's obviously wrong. It'd help to have the error and the line where the crash happens, but perhaps this is straying into new question territory.

Sorry...my fault. allSectors is an NSMutableArray which has NSSet inside it. Fix: cell.textLabel.text = [[self.allSectors objectAtIndex:indexPath.row] valueForKey:@"SECTORNAME"];
