如何从SKScene中指示使用UIKit创建的视图？ [英] How can I indicate a view which has created with UIKit from a SKScene?

问题描述

我有一个名为MainScene.swift的SKScene文件，并在其上创建了一个按钮，供用户跳转到另一个页面。另一个页面不是由SpriteKit创建的，而是由UIKit创建的。在这种情况下，如何指示目标页面和编写代码？

I have a file of SKScene which is named "MainScene.swift", and created a button on it for users to jump to another page. The another page was created not by SpriteKit but with UIKit. How can I indicate the target page and write codes in this case?

如果我使用SpriteKit创建了两个页面，我通常会在跳转到其他场景时这样做。

I usually do like this when jump to the other scene, if I created both pages with SpriteKit.

override func viewDidLoad() {
    super.viewDidLoad()

    let scene = MainScene(size: CGSize(width: 750, height: 1334))
    let skView = self.view as! SKView

    scene.scaleMode = .AspectFit
    skView.presentScene(scene)
}

当我在使用UIKit创建的场景上执行相同的操作时，在Identity列上键入Storyboard ID，然后像这样编码;我只知道使用故事板的方式。

And when I do the same thing on a scene which is created with UIKit, type a Storyboard ID on the Identity column, then code like this; I only know the way using storyboard.

class ViewController: UIViewController {
    @IBAction func gotoNewPage(sender: AnyObject) {
        let nextVC = self.storyboard?.instantiateViewControllerWithIdentifier("newPage")
    presentViewController(nextVC!, animated: false, completion: nil)    
    }
}

但是当在创建SKScene和UIKit的场景之间尝试同样的事情时，我不知道如何从前一个场景中指定后者;我不会坚持使用故事板。如果有任何简单的方法，请告诉我。提前谢谢。

But when try same thing between the scene which is created SKScene and UIKit, I've no idea how to specify the latter from the former scene; I'm not sticking to use the storyboard. If there's any simple way, please let me know. Thank you in advance.

推荐答案

这听起来像委托模式的工作。
为LevelScene添加协议;

This sounds like a job for the delegate pattern. Add a protocol for LevelScene;

// LevelScene.swift
protocol LevelScene : class {
    var gameDelegate: GameDelegate? { get set }
}

为GameDelegate添加协议;

Add a protocol for GameDelegate;

// GameDelegate.swift
protocol GameDelegate : class {
    func gameOver()
}

在你的mainScene中添加协议引用并创建一个名为gameDelegate的属性;

In your mainScene add the protocol reference and create a property called gameDelegate;

class MainScene: SKScene, LevelScene {
    weak var gameDelegate: GameDelegate?
}

在你的GameViewController中添加协议参考并实现所需的协议功能 - 在此case就像往常一样叫做gameOver和seque到你的UIKit View;

In your GameViewController add the protocol reference and implement the required protocol function - in this case it's called gameOver and seque to your UIKit View as usual;

class GameViewController: UIViewController, GameDelegate {
    func gameOver() {
        self.performSegue(withIdentifier: ExitGameSegueKey, sender: self)
    }
}

在呈现场景时将委托设置为gameViewController;

Set the delegate to gameViewController when presenting the scene;

scene.gameDelegate = self

然后在mainScene中调用委托函数;

Then in mainScene call the delegate function when required;

self.gameDelegate?.gameOver()
