Xcode Swift游乐场中的多个视图

在游乐场文件中,可以按如下方式创建场景视图:

let sceneView = SKView(frame: CGRect(x:0 , y:0, width: 640, height: 480))
let myScene = FirstView(fileNamed: "MyPlayground")

if let scene = myScene {
    scene.scaleMode = .aspectFill
    sceneView.presentScene(scene)
}

PlaygroundSupport.PlaygroundPage.current.liveView = sceneView

在第一个视图文件中,创建 FirstView 班不要忘记将其公开:

import Foundation
import SpriteKit

public class FirstView: SKScene {

    private var label : SKLabelNode!

    open override func didMove(to view: SKView) {
        // Get label node from scene and store it for use later
        label = SKLabelNode(text: "first view")
        label.position = view.center
        addChild(label)
    }
}
