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

    delete.image = [UIImage imageNamed:@"money_pop_icon"];//这里还可以设置图片
    delete.backgroundColor = HEX(0xF3F3F3);
    UISwipeActionsConfiguration *config = [UISwipeActionsConfiguration configurationWithActions:@[delete]];
    return config;
