本文介绍如何在UITableView中实现删除和插入操作。当用户选择删除时，将从数据源中移除对应的项并更新UITableView。若选择插入，则通过编辑视图控制器创建新项并将其添加到指定位置。

- (void)tableView:(UITableView *)aTableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
            forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        NSDictionary *section = [data objectAtIndex:indexPath.section];
        if (section) {
            NSMutableArray *content = [section valueForKey:@"content"];
            if (content && indexPath.row < [content count]) {
                [content removeObjectAtIndex:indexPath.row];
            }
        }
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
else if (editingStyle == UITableViewCellEditingStyleInsert) {
        NSDictionary *section = [data objectAtIndex:indexPath.section];
        if (section) {
            // Make a local reference to the editing view controller.
            EditingViewController *controller = self.editingViewController;
            NSMutableArray *content = [section valueForKey:@"content"];
            // A "nil" editingItem indicates the editor should create a new item.
            controller.editingItem = nil;
            // The group to which the new item should be added.
            controller.editingContent = content;
            controller.sectionName = [section valueForKey:@"name"];
            controller.editingTypes = [section valueForKey:@"types"];
            [self.navigationController pushViewController:controller animated:YES];
        }
    }
}

//那一行是要自己添加的然后把新加那一行的属性设置成UITableViewCellEditingStyleInsert就行了
