如何从 SKScene 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并编写代码?

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?

如果我用 SpriteKit 创建了两个页面，我通常会在跳转到另一个场景时这样做.

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 创建的场景上做同样的事情时，在 Identity 列中输入 Storyboard ID，然后像这样编写代码；我只知道使用情节提要的方式.

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 的场景之间尝试相同的事情时，我不知道如何从前一个场景中指定后者；我不坚持使用情节提要.如果有任何简单的方法，请告诉我.提前谢谢你.

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

这听起来像是委托模式的工作.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()
}

在您的 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?
}

在您的 GameViewController 中添加协议引用并实现所需的协议功能 - 在这种情况下，它被称为 gameOver 并像往常一样连接到您的 UIKit 视图；

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)
    }
}

在呈现场景时将代理设置为gameViewController；

Set the delegate to gameViewController when presenting the scene;

scene.gameDelegate = self

然后在 mainScene 需要的时候调用委托函数；

Then in mainScene call the delegate function when required;

self.gameDelegate?.gameOver()
