UITableView row order - ios

Question

I have a strange behavior my tableView
I make dropdown section on my tableView. It's look like:
but if I reopen my section rows order was ather like this:
- (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];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
NSLog(#"CURRENT ROW = %ld", (long)indexPath.row);
UILabel *titleLable = [[UILabel alloc] initWithFrame:CGRectMake(90, 20, cell.frame.size.width - 90, 20)];
titleLable.text = [NSString stringWithFormat:#"урок %ld", (long)indexPath.row];
[cell addSubview:titleLable];
UILabel *percentLable = [[UILabel alloc] initWithFrame:CGRectMake(cell.frame.size.width - 40, 20, 50, 20)];
LessonModel *lesson = [self.lessonsArray objectAtIndex:indexPath.section];
NSArray *childrenArrey = [[NSArray alloc] initWithArray:(NSArray *) lesson.childrenArray];;
percentLable.text =[NSString stringWithFormat:#"%# %%", [childrenArrey[indexPath.row] valueForKey:#"percent"]];
[cell addSubview:percentLable];
}
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[self.tableView deselectRowAtIndexPath:indexPath animated:YES];
LessonModel *lesson = [self.lessonsArray objectAtIndex:indexPath.section];
NSArray *childrenArrey = [[NSArray alloc] initWithArray:(NSArray *) lesson.childrenArray];
NSString *uid = [childrenArrey[indexPath.row] valueForKey:#"id"];
[self makeLessonWithId:uid];
}
- (void)sectionHeaderTapped:(UITapGestureRecognizer *)gestureRecognizer{
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:gestureRecognizer.view.tag];
if (indexPath.row == 0) {
BOOL collapsed = [[self.arrayForBool objectAtIndex:indexPath.section] boolValue];
collapsed = !collapsed;
[self.arrayForBool replaceObjectAtIndex:indexPath.section withObject:[NSNumber numberWithBool:collapsed]];
[self updateLabelFrame:gestureRecognizer.view.tag];
NSRange range = NSMakeRange(indexPath.section, 1);
NSIndexSet *sectionToReload = [NSIndexSet indexSetWithIndexesInRange:range];
[self.tableView reloadSections:sectionToReload withRowAnimation:UITableViewRowAnimationFade];
}
}

Try by putting values in else part too:
if (cell == nil){
//your code as it is
}
else{
titleLable.text = [NSString stringWithFormat:#"урок %ld", (long)indexPath.row];
NSArray *childrenArrey = [[NSArray alloc] initWithArray:(NSArray *) lesson.childrenArray];;
percentLable.text =[NSString stringWithFormat:#"%# %%", [childrenArrey[indexPath.row] valueForKey:#"percent"]];
}
