无法在 ViewController 和 SKScene 之间设置委托

Question

我想在我的 GameViewController 和 SKScene 文件之间设置委托，但遇到错误。我的目标是从 SKScene 文件中调用方法。

错误是：'GameScene' 类型的值没有成员 'gameViewControllerDelegate'

我做错了什么？

提前致谢

MainSC.swift

import UIKit
import SpriteKit
import Firebase
import StoreKit
import GoogleMobileAds

class MainVC: UIViewController, GameViewControllerDelegate {


    override func viewDidLoad() {
        super.viewDidLoad()

     if let view = self.view as! SKView? {

            if let scene = SKScene(fileNamed: "GameScene") {
                let gameScene = scene as! GameScene

                //THIS GUY THROWING ERROR
                 gameScene.gameViewControllerDelegate = self 

                gameScene.scaleMode = .aspectFill
                gameScene.size.width = 414
                gameScene.size.height = 736
                view.presentScene(gameScene)

            }

            view.ignoresSiblingOrder = true

            view.showsFPS = true
            view.showsNodeCount = true
            view.showsPhysics = true

        }
    }
func callMethod(inputProperty:String) {
        print("inputProperty is: ",inputProperty)
    }
}

MainSC.swift

import UIKit
import SpriteKit
import GameplayKit
import Firebase
import GoogleMobileAds

protocol GameViewControllerDelegate : class {
    func callMethod(inputProperty:String)
}

class MainSC: SKScene {

    weak var gameViewControllerDelegate : GameViewControllerDelegate?

override func didMove(to view: SKView) {

       ...

       gameViewControllerDelegate?.callMethod(inputProperty: "call game view controller method")

    }

}

Answer 1

您没有在 MainVC 中将 gameViewControllerDelegate 委托设置为 self 那么怎么可能调用该 SKscene 的委托。所以在 MainVC

中设置为 self

无法在 ViewController 和 SKScene 之间设置委托

Can't set delegate between ViewController and SKScene

delegates

viewcontroller
