我该怎么办？在SpriteKit swift中它说：Type＆＃39; GameScene＆＃39;不符合协议＆＃39; GKGameCenterControllerDelegate＆＃39;？

Question

我在SpriteKit swift编码，直到我收到此错误说，＆＃34; Type＆＃39; GameScene＆＃39;不符合协议＆＃39; GKGameCenterControllerDelegate＆＃39; ＆＃34 ;.我该怎么办？该错误出现在类GameScene上。 （错误不是我没有结束括号，因为我的结束括号位于下方，我没有显示）：

import SpriteKit
import GameKit
import UIKit
import GoogleMobileAds
struct PhysicsCategory {
static let Enemy :UInt32 = 0x1 << 0
static let SmallBall : UInt32 = 0x1 << 1
static let Mainball :UInt32 = 0x1 << 2
}

class GameScene: SKScene, SKPhysicsContactDelegate, GKGameCenterControllerDelegate,GADBannerViewDelegate {

    var Mainball = SKSpriteNode(imageNamed: "MainBall")
    var redmain = SKSpriteNode(imageNamed: "white")
    var greenmain = SKSpriteNode(imageNamed: "white")
    var darkred = SKSpriteNode(imageNamed: "white")
    var orange = SKSpriteNode(imageNamed: "white")
    var yellow = SKSpriteNode(imageNamed: "white")
    var lightblue = SKSpriteNode(imageNamed: "white")
    var blue = SKSpriteNode(imageNamed: "white")
    var purple = SKSpriteNode(imageNamed: "white")
    var pink = SKSpriteNode(imageNamed: "white")
    var origin = SKSpriteNode(imageNamed: "white")

Answer 1

你需要在某处实现这个方法

gameCenterViewControllerDidFinish(_:)

请参阅apple的文档here

Answer 2

您声明GameScene符合GKGameCenterControllerDelegate，但您尚未实施所有必要的方法。

您需要在班级中实施gameCenterViewControllerDidFinish(_:)。
