教程里面讲了prepareForSegue的替代方法，贴出来看一下

    override func tableView(tableView: UITableView, accessoryButtonTappedForRowWithIndexPath indexPath: NSIndexPath) {                // 这个函数和prepare for segue 相同作用                // Tells the delegate that the user tapped the accessory (disclosure) view associated with a given row.                //This time you’re not going to use a segue at all, but load the new view controller by hand from the storyboard.                let navigationController = storyboard!.instantiateViewControllerWithIdentifier("ListDetailNavigationController") as! UINavigationController                let controller = navigationController.topViewController as! ListDetailViewController                controller.delegate = self                                let checklist = lists[indexPath.row]                controller.checklistToEdit = checklist                presentViewController(navigationController,animated: true, completion: nil)                // Presents a view controller modally.    }

可以看到，这里用的是tableView(accessoryButtonTappedForRowWithIndexPath)函数。即用户点了一下时候的动作。用"ListDetailNavigationController"指代ListDetailViewController的UINavigationController。使用这个方法之前，我们需要先将这个UINavigationController的storyboard ID改为ListDetailNavigationController
