Scaling SpriteKit游戏

Question

什么是最好的方法来外观图像拟合蓝框？这个游戏是基于像素的，所以我想保持它的像素化外观。

根据实际的Swift 2.2，您可以发现：

@available(iOS 7.0, *)
public enum SKSceneScaleMode : Int {

    case Fill /* Scale the SKScene to fill the entire SKView. */
    case AspectFill /* Scale the SKScene to fill the SKView while preserving the scene's aspect ratio. Some cropping may occur if the view has a different aspect ratio. */
    case AspectFit /* Scale the SKScene to fit within the SKView while preserving the scene's aspect ratio. Some letterboxing may occur if the view has a different aspect ratio. */
    case ResizeFill /* Modify the SKScene's actual size to exactly match the SKView. */
} 

例如，你可以在你的viewController中这样做：

override func viewDidLoad() {
        super.viewDidLoad()

        if let scene = PreloadScene(fileNamed:"PreloadScene") {
            // Configure the view.
            let skView = self.view as! SKView
            ...
            /* Set the scale mode to scale to fit the window */
            scene.scaleMode = .AspectFit 
            ...
            skView.presentScene(scene)
        }
    }

或者从一个SKScene过渡到另一个SKScene

let transition = SKTransition.doorsOpenVerticalWithDuration(0.5)
let nextScene = MainScene(size: self.scene!.size)
nextScene.scaleMode = .AspectFit
self.scene?.view?.presentScene(nextScene, transition: transition)
