有没有办法跟踪用户在 Swift Playgrounds 中输入的内容？

如何解决有没有办法跟踪用户在 Swift Playgrounds 中输入的内容？

我想知道是否有办法跟踪用户在 swift playgrounds 中输入的内容并将其显示在实时 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:)

解决方法

要处理按下的键，您应该重写 keyDown 的 keyUp 或 SKScene 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
