CoreData with relationship in the same UItableView - uitableview

Question

I need to load the "Main Entity" that has a relationship one-to-many with "Child Entity" into the same UITableView, how can i do?
Thanks in advance.
Update
i use the following code to populate the UITableView:
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return [[[fetchedResultsController sections] objectAtIndex:section] name];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
id <NSFetchedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex:section];
if (self.selectedIndexPath) {
return [sectionInfo numberOfObjects] + [self.childArray count];
}else {
return [sectionInfo numberOfObjects];
}
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
OreRecupero *selectedObj=(OreRecupero*)[self.fetchedResultsController objectAtIndexPath:indexPath];
OrarioMainCell *cell = nil;
if (indexPath == self.selectedIndexPath) {
NSUInteger giorniCount = [selectedObj.giorni count];
NSInteger row = indexPath.row;
if (indexPath.row < giorniCount) {
cell = (OrarioMainCell *)[tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil) {
cell=(OrarioMainCell *)[[[NSBundle mainBundle]loadNibNamed:#"myCustomCell" owner:self options:nil]objectAtIndex:11];
radiusLabel=[[LabelRadiusAndText alloc]init];
}
UIImageView *bgImage=[[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"fondoCella"]]autorelease];
cell.backgroundView=bgImage;
[df setDateFormat:#"HH:mm"];
cell.textLabel.text = [NSString stringWithFormat:#"%# - %#",[df stringFromDate:selectedObj.oraInizio],[df stringFromDate:selectedObj.oraFine]];
} else {
cell = (OrarioMainCell *)[tableView dequeueReusableCellWithIdentifier:#"DetailCell"];
if (cell == nil) {
cell=(OrarioMainCell *)[[[NSBundle mainBundle]loadNibNamed:#"myCustomCell" owner:self options:nil]objectAtIndex:13];
radiusLabel=[[LabelRadiusAndText alloc]init];
}
GiornoRecupero *giorno = [childArray objectAtIndex:row];
cell.textLabel.text = [NSString stringWithFormat:#"%i", giorno.oreStraordinario];
cell.detailTextLabel.text = [NSString stringWithFormat:#"%i", giorno.durata];
}
} else {
cell = (OrarioMainCell *)[tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil) {
cell=(OrarioMainCell *)[[[NSBundle mainBundle]loadNibNamed:#"myCustomCell" owner:self options:nil]objectAtIndex:11];
radiusLabel=[[LabelRadiusAndText alloc]init];
}
UIImageView *bgImage=[[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"fondoCella"]]autorelease];
cell.backgroundView=bgImage;
[df setDateFormat:#"HH:mm"];
cell.orariLbl.text = [NSString stringWithFormat:#"%# - %#",[df stringFromDate:selectedObj.oraInizio],[df stringFromDate:selectedObj.oraFine]];
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
OreRecupero *selectedObj=(OreRecupero*)[self.fetchedResultsController objectAtIndexPath:indexPath];
NSIndexPath *dropDownCellIndexPath = [NSIndexPath indexPathForRow:indexPath.row + 1
inSection:indexPath.section];
//if user tapped the same row twice let's start getting rid of the control cell
if (!self.selectedIndexPath) {
// Show Drop Down Cell
for (GiornoRecupero *giorno in selectedObj.giorni) {
[self.childArray addObject:giorno];
}
[tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:dropDownCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
self.selectedIndexPath = indexPath;
} else {
NSIndexPath *currentdropDownCellIndexPath = [NSIndexPath indexPathForRow:self.selectedIndexPath.row + 1
inSection:self.selectedIndexPath.section];
if (indexPath.row == self.selectedIndexPath.row) {
// Hide Drop Down Cell
[self.childArray removeAllObjects];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:currentdropDownCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
self.selectedIndexPath = nil;
} else if (indexPath.row == currentdropDownCellIndexPath.row) {
// Dropdown Cell Selected - No Action
return;
} else {
// Switch Dropdown Cell Location
[self.myTableView beginUpdates];
// Hide Dropdown Cell
[self.childArray removeAllObjects];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:currentdropDownCellIndexPath]
withRowAnimation:UITableViewRowAnimationAutomatic];
// Show Dropdown Cell
NSInteger dropDownCellRow = indexPath.row + ((indexPath.row >= currentdropDownCellIndexPath.row) ? 0 : 1);
dropDownCellIndexPath = [NSIndexPath indexPathForRow:dropDownCellRow
inSection:indexPath.section];
for (GiornoRecupero *giorno in selectedObj.giorni) {
[self.childArray addObject:giorno];
}
[tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:dropDownCellIndexPath]
withRowAnimation:UITableViewRowAnimationAutomatic];
self.selectedIndexPath = [NSIndexPath indexPathForRow:dropDownCellIndexPath.row - 1
inSection:dropDownCellIndexPath.section];
[self.myTableView endUpdates];
}
}
}
i would like to insert new rows using didSelectRowAtIndexPath method, getting data from "Child Entity"
