我做了一个简单的游戏，你必须躲避障碍并收集硬币。每枚硬币将给您1分。在玩游戏时，有一个得分标签。如何创建高分标签，即使他们退出游戏也会记住高分。我也想知道如何将高分与游戏中心联系起来。

任何帮助将非常感激。

到目前为止，这是我确定获胜者何时赢得比赛的方式。

func didBeginContact(contact: SKPhysicsContact) {
    var firstBody = SKPhysicsBody()
    var secondBody = SKPhysicsBody()

    if contact.bodyA.categoryBitMask < contact.bodyB.categoryBitMask {
        firstBody = contact.bodyA
        secondBody = contact.bodyB
    } else {
        firstBody = contact.bodyB
        secondBody = contact.bodyA
    }


    if (firstBody.categoryBitMask & UInt32(shipCategory)) != 0 && (secondBody.categoryBitMask & UInt32(obstacleCategory)) != 0 {
        ship.removeFromParent()
        let reveal = SKTransition.flipHorizontalWithDuration(0.5)
        let scene = GameOverScene(size: self.size)
        self.view?.presentScene(scene, transition: reveal)
    }

    if (firstBody.categoryBitMask & UInt32(shipCategory)) != 0 && (secondBody.categoryBitMask & UInt32(coinCategory)) != 0 {
        coin.removeFromParent()
        playerScore = playerScore + 1
        playerScoreUpdate()
    }

    //CHANGE TO YOU WON SCENE
    //CHECK TO SEE IF COINS ARE 10, THEN YOU WON
    if playerScore == 10 {

        let reveal = SKTransition.flipHorizontalWithDuration(0.5)
        let scene = GameWonScene(size: self.size)
        self.view?.presentScene(scene, transition: reveal)

    }



}

func addHighScoreLabel() {

    highScoreLabel.fontSize = 28
