Do not delete cell using the TableView section - ios

Question

Hello I'm having trouble deleting a cell / record after it implemented the section in tableview.
See the code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"celula";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
alimento *p = [sessaoAlimento objectAtIndex:indexPath.section];
crudAlimento *obj = [[crudAlimento alloc] init];
NSArray *arrayAlime = [obj listarAlimentoSessao:[p tipoAlimento] filtro:srBar.text];
alimento *objAlimento = [arrayAlime objectAtIndex:indexPath.row];
NSString *registro = [NSString stringWithFormat:#"%# - %#", [objAlimento alimentoid], [objAlimento nomeAlimento]];
[[cell textLabel]setText:registro];
return cell;
}
detail is that I can not use object id to pass to the method
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
crudAlimento *deleteAlimento = [[crudAlimento alloc] init];
alimento *objUsuario = [arrayAlimento objectAtIndex:indexPath.row];
[deleteAlimento deletar:objUsuario];
[self carregaListaSessao:#""];//com sessao
}

I'm struggling a little with the language gap, but it looks like you are trying to delete an object from an empty crudAlimento object. You are creating a new one:
crudAlimento *deleteAlimento = [[crudAlimento alloc] init]; // this is empty unless you're overriding the init method in crudAlimento
And then deleting an item from it:
[deleteAlimento deletar:objUsuario]; // deleting an object from an empty source
From the looks of things, it's hard to tell if your data source for your table is mutable, but assuming it is, I think you need to remove a sub-element of sessaoAlimento (something like sessaoAlimento[indexPath.section].tipoAlimento[indexPath.row])
