• 编辑状态下删除

与左滑返回区别: 设置编辑状态为YES

self.tableView.editing = !self.tableView.editing;

//编辑风格为删除
if (self.editingStyle == CCTableViewCellEditingStyleDelete) {
            return UITableViewCellEditingStyleDelete;
        }

点击编辑，出现减号，再点击减号 出现左滑返回按钮 点击左滑返回按钮 删除数据

• 编辑状态下插入

//编辑风格为插入
if (self.editingStyle == CCTableViewCellEditingStyleInsert) {
            return UITableViewCellEditingStyleInsert;
        }

//插入操作
[self.dataArray insertObject:@"cc" atIndex:indexPath.row];//插入数据
        [tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];

• 编辑风格为删除和插入共存

左滑删除很多应用中都会此功能，而其他的系统自带功能或许并不一定符合实际需求；关于多选删除，过几天会分享一个小例子
