Question

I have 2 views we are dealing with. Main View, and Sub View.

Main View’s tablecell’s string shows the count of the number of objects in that cell’s subView. When I delete a cell from the subview, and go back to the mainView, the string that shows the count should go down by 1. Right now this string is not changing until I restart the app.

Any ideas how I can fix this? The count is being pulled from a NSFetch.

Edit: Added Code

- (void)configureCell:(TDBadgedCell *)cell atIndexPath:(NSIndexPath *)indexPath
{
    NSDate *today = [NSDate date]; 
    NSDate *thisWeek  = [today dateByAddingTimeInterval: -604800.0];
    NSDate *thisMonth = [today dateByAddingTimeInterval: -2629743.83];
    else if (indexPath.row == 2)
    {
        NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
        self.predicate = [NSPredicate predicateWithFormat:@"(timeStamp >= %@) AND (timeStamp <= %@)", thisWeek, today];
        [fetchRequest setPredicate: predicate];
        [fetchRequest setEntity:[NSEntityDescription entityForName:@"Session" inManagedObjectContext:managedObjectContext]];
        NSError *error = nil;
        NSArray *results = [managedObjectContext executeFetchRequest:fetchRequest error:&error];
        NSLog(@"Fetch error: %@", error);

        cell.badgeString = [NSString stringWithFormat:@"%i", [results count]];
        [fetchRequest release];
    }
    else if (indexPath.row == 3)
    {
        NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
        self.predicate = [NSPredicate predicateWithFormat:@"(timeStamp >= %@) AND (timeStamp <= %@)", thisMonth, today];
        [fetchRequest setPredicate:predicate];
        [fetchRequest setEntity:[NSEntityDescription entityForName:@"Session" inManagedObjectContext:managedObjectContext]];

        NSError *error = nil;
        NSArray *results = [managedObjectContext executeFetchRequest:fetchRequest error:&error];
        NSLog(@"Fetch error: %@", error);

        cell.badgeString = [NSString stringWithFormat:@"%i", [results count]];
        [fetchRequest release];
    }
    else if (indexPath.row == 4)
    {
        cell.badgeString = [NSString stringWithFormat:@"%i", [[self.fetchedResultsController fetchedObjects] count]];
    }

If your data is in fact being updated correctly on the model side of things, you should be able to call

[tableView reloadData];

and everything will update correctly. You can probably put this in viewWillAppear.

Hope this helps.
