This is because your numberOfRowsInSection data source implementation always returns 1 (fixed).

Typically, you store objects in an array, which defines the number of rows. And, commitEditingStyle should remove the object from the array and then delete the row.

– (void)tableView: (UITableView *)tableView commitEditingStyle: (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath: (NSIndexPath *)indexPath {if (editingStyle == UITableViewCellEditingStyleDelete) {
       // Delete the row from the data source
       [maTheData removeObjectAtIndex:[indexPath row]];
       // Delete row using the cool literal version of [NSArray arrayWithObject:indexPath]

       [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];

    }
}
