在Swift Sprite-Kit游戏中实现游戏菜单

Question

I have created a platformer game, and I when I start the game, it goes straight into playing. I would like to have a menu that has a button to start the game and a button which would lead to a shop, to purchase different backgrounds or characters with in game currency that has been earned. I would appreciate it if someone could help me to implement this kind of menu. It would also be great if I could get help on how to pause the game while playing.

You could create scene for menu. When user push start button you present your game scene.

class MenuScene: SKScene {

    override func didMoveToView(view: SKView) {
        addButtons()
    }

    private func addButtons() {
        // TODO layout buttons here
    }

    private func startGame() {
        let gameScene = GameScene(size: view!.bounds.size)
        let transition = SKTransition.fadeWithDuration(0.15)
        view!.presentScene(gameScene, transition: transition)
    }
}

And present it from your controller:

override func viewDidLoad() {
    super.viewDidLoad()

    let sceneView = view as! SKView
    // sceneView.showsFPS = true
    // sceneView.showsNodeCount = true
    sceneView.ignoresSiblingOrder = true

    scene = MenuScene(size: view.bounds.size)
    scene.scaleMode = .ResizeFill
    sceneView.presentScene(scene)
}
