ios - presentScene 导致错误的 View 加载

Question

我有一个名为 NeighborhoodViewController 的 viewController。它将场景加载到 viewController 中，称为 NeighborhoodScene.sks。这绝对没问题。我已经通过 NeighborhoodViewController 从场景中的特定节点设置了一个 segue。这两个函数控制这个:

func createSegue(title: String) {
    performSegueWithIdentifier(title, sender: self)
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if let viewController: SearchViewController = segue.destinationViewController as? SearchViewController {
        viewController.sceneName = "game_1_1"
    }
}

一切正常。正在调用 segue。 segue 旨在调出另一个名为 SearchViewController 的 VC，它应该调出自己的场景 SearchScene1.sks。

这是它的代码:

import UIKit
import SpriteKit

class SearchViewController: UIViewController {
var sceneName: String?
var chosenScene: GameScene?

override func viewDidLoad() {
    super.viewDidLoad()

    if sceneName == "game_1_1" {
        chosenScene = GameScene(fileNamed: "SearchScene1")
    } // TODO: add the rest of the presented scenes here

    if let scene = chosenScene {
        // Configure the view.
        let skView = self.view as! SKView
        skView.showsPhysics = true
        skView.showsFPS = true
        skView.showsNodeCount = true

        /* Sprite Kit applies additional optimizations to improve rendering performance */
        skView.ignoresSiblingOrder = false

        /* Set the scale mode to scale to fit the window */
        scene.scaleMode = .AspectFill
        scene.viewController = self
        skView.presentScene(chosenScene)
    }
}
}

如果我打印出 skView 的 restorationidentifier，它属于 SearchViewController 中的 View ，这是完美的。在 skView.presentScene(chosenScene) 之前一切似乎都工作正常，此时它似乎随机设置了 NeighborhoodViewController？我如何让它调用 SearchViewController 和关联的 sks 场景 -- SearchScene1？

segue 用于首先引入 nextviewcontroller。
