我想创建第二个按钮，但它没有出现 - Xcode 6 Swift

Question

这是我正在使用的代码，但是当我测试应用程序时，第二个按钮“分数”没有出现，为什么？

class GameScene: SKScene {

    let playbutton = SKSpriteNode (imageNamed: "play")
    let score = SKSpriteNode (imageNamed: "score")

    override func didMoveToView(view: SKView) {
        self.playbutton.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame))
        self.addChild(self.playbutton)
        self.backgroundColor  = UIColor(hex: 0x80D9FF)

    func didMoveToView(view: SKView) {
        self.score.position = CGPointMake(180, 100)
        self.addChild(self.score)
        self.backgroundColor  = UIColor(hex: 0x80D9FF)
    }
}

Answer 1

你有没有调用过第二个 didMoveToView() ？您是否尝试过像这样在原始覆盖函数 didMoveToView(view: SKView) 中包含添加分数的代码：

class GameScene: SKScene {

    let playbutton = SKSpriteNode (imageNamed: "play")
    let score = SKSpriteNode (imageNamed: "score")

    override func didMoveToView(view: SKView) {
        self.playbutton.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame))
        self.addChild(self.playbutton)
        self.backgroundColor  = UIColor(hex: 0x80D9FF)

        self.score.position = CGPointMake(180, 100)
        self.addChild(self.score)
        self.backgroundColor  = UIColor(hex: 0x80D9FF)
    }
}
