ios - How to remember rows selected and maintain them after reload by default in UITableView?

Question

How can I set a row selected by default? I want to select a row , take the number of selected row with indexpath.row and then reload the table and select the row what was selected. Can someone help me please? Can I get the selected row in a method -(IBAction) segmentedControlIndexChanged? Not in didSelectRowAtIndexPath?

This is my code if it can help you to understand

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    //lbl1 = [[UILabel alloc]initWithFrame:CGRectMake(200, 10, 100, 20) ];

    // Configure the cell...
    NSString *depdateChoosed=[deparatureDates objectAtIndex:depSelectedIndice];
    NSString *comeateChoosed=[deparatureDates objectAtIndex:comSelectedIndice];
    NSString *choosedDate =[NSString stringWithFormat:@"%@%@",depdateChoosed, comeateChoosed];
    NSLog(@"date choisi %@ ",choosedDate);

    if(segment.selectedSegmentIndex==0)
    {
        cell.textLabel.text =[deparatureDates objectAtIndex:indexPath.row];        
    }
    else if(segment.selectedSegmentIndex==1) {
         //cell.textLabel.text =[goingBackDates objectAtIndex:indexPath.row];
        //cell.textLabel.text=[goingBackDates objectAtIndex:indexPath.row];
        cell.textLabel.text =[goingBackDates objectAtIndex:indexPath.row];
    }
    return cell;
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@" champ séléctionner : %d ",indexPath.row);

    if(segment.selectedSegmentIndex==0)
    {
        depSelectedIndice=indexPath.row;  
    }
    else if(segment.selectedSegmentIndex==1) {
        comSelectedIndice=indexPath.row;
    }
    //[tableView reloadData];
}

-(IBAction) segmentedControlIndexChanged
{
    int i;
    switch (self.segment.selectedSegmentIndex) 
    {
        case 0:
            i=0;

            [tableView reloadData];
            break;
        case 1:
            i=1;
            NSLog(@"dexieme segment selectionner");
            [tableView reloadData];
        default:
            break;
    }
}

Answer 1

NSIndexPath *indexPath = [tableView indexPathForSelectedRow];

will give you the NSIndexPath for the current selected row. You can then do

[tableView selectRowAtIndexPath:indexPath 
                       animated:NO 
                 scrollPosition:UITableViewScrollPositionMiddle];

to select that row (and show it in the middle of the screen) later.
