Question

I have a parent view (table) that passes a detail object to the child view (table).

The parent view has a network request that gets data and passes data to the child view.

I want to be able to update the data when I’m in the child view. I think I need to call the parent view’s network request method while viewing the child view, and update the child table. Is this possible?

In Parent VC:

- (void)fetchAppointmentsForVisibleDate {   
    self.appointmentArray = [DataSource getTodayData:self.visibleDate];

    NSMutableArray *array = [NSMutableArray arrayWithCapacity:50];
    for (NSDictionary *appointment in self.appointmentArray)
    {
        [array addObject: [NSString stringWithFormat:@"%@: %@", [appointment objectForKey:@"scheduled_time"], [appointment objectForKey:@"patient"]]];
    }
    self.listData = array;

    [self.appointmentTableView reloadData];
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    ChildVC *vc = [Child VC alloc]initWithNib@"ChildVC"];
    vc.appointmentDictionary = [self.appointmentArray objectAtIndex:path.row];
}

Answer 1

Is your network request is bound to be called by parent view.

If its just a method you can set the delegate of your child to the parent.
i.e in the parent view you can do

create child object and just do

child.delegate=self;

and call your network method from child

i.e [delegate networkMethod];
