Using insert rows in a UITableView

I was missing one thing. In setEditing:, instead of calling reloadData I should have done:

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
    [super setEditing:editing animated:animated];
    [self.tableView setEditing:editing animated:animated]; // not needed if super is a UITableViewController

    NSMutableArray* paths = [[NSMutableArray alloc] init];

    // fill paths of insertion rows here

    if( editing )
        [self.tableView insertRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationBottom];
    else
        [self.tableView deleteRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationBottom];

    [paths release];
}
