Swift - 显示术语 "inView"的错误

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 不允许我放置“coinFlip”函数!它说我必须在“inView”之后加一个逗号，然后它说“Use of unresolved identifier 'inView'”。在这种情况下我该怎么办？

Answer 1

Coin 类不继承自具有 View 属性的类。假设您想在抛硬币方法中引用 View ，向函数添加一个参数以将其传入。

func coinFlip(inView view: UIView)
