【问题描述】：

我想知道是否有一种方法可以跟踪用户在 swift Playground 中输入的内容并将其显示在现场 Playground 中？我似乎无法在网上找到有关此的任何信息。任何帮助都会很棒:)

【参考方案1】：

要处理按下的键，您应该覆盖 SKScene 的 keyDown 或 keyUp 方法，例如：

class MyScene: SKScene 
    
    public override func keyDown(with event: NSEvent) 
        super.keyDown(with: event)
        handleKeyEvent(event: event, down: true)
    
        
    public override func keyUp(with event: NSEvent) 
        super.keyUp(with: event)
        handleKeyEvent(event: event, down: false)
    
    
    func handleKeyEvent(event: NSEvent, down: Bool) 
        if let key = event.characters?.first 
            print("Key: '\(key)' - \(down ? "Down" : "Up")")
        
    


let view = SKView(frame: CGRect(x: 0, y: 0, width: 1024, height: 768))
let scene = MyScene(size: CGSize(width: 1024, height: 768))
scene.scaleMode = SKSceneScaleMode.aspectFit
view.presentScene(scene)

PlaygroundPage.current.liveView = view
PlaygroundPage.current.needsIndefiniteExecution = true
