swift - SpriteKit 使图像适合屏幕，而不是拉伸(stretch)过去

Question

我正在处理一个项目，SKNode 不会根据设备大小动态调整大小。

例子:

我希望第一张图片上发生的事情在第二张图片上发生。 有什么可以让这一切自动发生吗？

显示图像的当前尺寸:

    background.position = CGPoint(x: frame.size.width / 2, y: frame.size.height / 2)
    background.size = CGSize(width: background.size.width / 5.5, height: background.size.height / 5.5)

游戏 View Controller :

import UIKit
import SpriteKit

class GameViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

    // Configure the view.
    let skView = self.view as! SKView
    skView.showsFPS = false
    skView.showsNodeCount = false

    let scene = GameScene(size: skView.bounds.size)

    scene.controller = self
    scene.size = skView.bounds.size

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

    /* Set the scale mode to scale to fit the window */
    scene.scaleMode = .AspectFill

    skView.presentScene(scene)
}

override func shouldAutorotate() -> Bool {
    return true
}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
        return .AllButUpsideDown
    } else {
        return .All
    }
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Release any cached data, images, etc that aren't in use.
}

override func prefersStatusBarHidden() -> Bool {
    return true
}
}

如果您希望在具有更大屏幕的设备上显示游戏时调整整个场景的大小，您只需打开 GameViewController.swift 并确保您使用的是 AspectFill

scene.scaleMode = .AspectFill
