Question

I can’t figure out why my tableView isn’t updating after I tap the delete button.

Once I click it, the table view “freezes”. If I click another row, so that the tableview goes to another level of the hierarchy and click back, I can see that the item has been deleted and everything works fine.

Here is my code:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 
{
    //[tableView beginUpdates];    
    if (editingStyle == UITableViewCellEditingStyleDelete) 
    {
        // Do whatever data deletion you need to do...
        [tableView beginUpdates];
        NSManagedObject *obj = (NSManagedObject *)[entityArray objectAtIndex:indexPath.row];        
        [managedObjectContext deleteObject:obj];
        NSError *error;
        [managedObjectContext save:&error];

        // Delete the row from the data source
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:YES];

         [self viewWillAppear:YES];

    }
    //[tableView endUpdates];
}

Any input on this problem would be appreciated.

Thanks.

I can’t see a call to [tableView endUpdates] matching the [tableView beginUpdates] that is at start of the if.

Could it be for this reason that your table freezes?
