Question

import SpriteKit
import UIKit
import Foundation

class GameScene: SKScene {

let coin = Coin()

    override func didMoveToView(view: SKView) {
    /* Setup your scene here */
        coin.coinFlip(inView view: UIView)

        }

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

override func update(currentTime: CFTimeInterval) {
    /* Called before each frame is rendered */
}
}

Xcode不会让我把'＃34; coinFlip＆＃34;功能！它说我必须在＆＃34; inView之后加一个逗号，＆＃34;然后它说＆＃34;使用未解析的标识符＆＃39; inView＆＃39;＆＃34; 。在这种情况下我该怎么办？

Answer 1

类Coin不会从具有view属性的类继承。假设您想在翻转硬币方法中引用该视图，请向该函数添加一个参数以将其传入。

func coinFlip(inView view: UIView)

Swift - 显示术语＆＃34; inView＆＃34;
