我创建了一个SKSpriteNode黑色的游戏,当用户触摸屏幕时,我希望将SKSpriteNode其更改为白色.我用谷歌搜索了所有可能的东西,尝试了许多不同的策略而没有运气.有谁知道如何做到这一点？

这是我的场景的代码:

var blackBird = SKSpriteNode()

override func didMoveToView(view: SKView) {
    //Black Bird
    var blackBirdTexture = SKTexture(imageNamed:"blackbird")
    blackBirdTexture.filteringMode = SKTextureFilteringMode.Nearest

    blackBird = SKSpriteNode(texture: blackBirdTexture)
    blackBird.setScale(0.5)
    blackBird.position = CGPoint(x: self.frame.size.width * 0.35, y:
        self.frame.size.height * 0.6)

    blackBird.physicsBody =
        SKPhysicsBody(circleOfRadius:blackBird.size.height/2.0)
    blackBird.physicsBody!.dynamic = true
    blackBird.physicsBody!.allowsRotation = false

    self.addChild(blackBird)
}

override func touchesBegan(touches: Set<NSObject, withEvent event: UIEvent) {
    /* Called when a touch begins */

    for touch: AnyObject in touches {
    let location = touch.locationInNode(self)

    blackBird.color = .whiteColor()
    blackBird.colorBlendFactor = …

苹果已经在手机中添加了一般>辅助功能>反转颜色的功能，我可以在我的程序中以某种方式使用它，例如当用户触摸屏幕时颜色反转吗？
