我对 Swift 和 iOS 开发都很陌生。
我一直在开发一款基于 Apple 的 SpriteKit(集成了 GameplayKit)模板的游戏。
一切正常,直到我将 GameScene.swift 和 GameScene.sks 重命名为 MapMainScene.swift 和 MapMainScene.sks。我确保在 GameViewController.swift 中更改此代码:
override func viewDidLoad() {
super.viewDidLoad()
// Load 'GameScene.sks' as a GKScene. This provides gameplay related content
// including entities and graphs.
if let scene = GKScene(fileNamed: "GameScene") {
// Get the SKScene from the loaded GKScene
if let sceneNode = scene.rootNode as! GameScene? {
// Copy gameplay related content over to the scene
sceneNode.entities = scene.entities
sceneNode.graphs = scene.graphs
// Set the scale mode to scale to fit the window
sceneNode.scaleMode = .aspectFill
// Present the scene
if let view = self.view as! SKView? {
view.presentScene(sceneNode)
view.ignoresSiblingOrder = true
view.showsFPS = true
view.showsNodeCount = true
}
}
}
}
到:
override func viewDidLoad() {
super.viewDidLoad()
// Load 'MainMapScene.sks' as a GKScene. This provides gameplay related content
// including entities and graphs.
if let scene = GKScene(fileNamed: "MainMapScene") {
// Get the SKScene from the loaded GKScene
if let sceneNode = scene.rootNode as! MainMapScene? {
// Copy gameplay related content over to the scene
sceneNode.entities = scene.entities
sceneNode.graphs = scene.graphs
// Set the scale mode to scale to fit the window
sceneNode.scaleMode = .aspectFill
// Present the scene
if let view = self.view as! SKView? {
view.presentScene(sceneNode)
view.ignoresSiblingOrder = true
view.showsFPS = true
view.showsNodeCount = true
}
}
}
}
我还在 Gamescene.swift
中更改了以下内容:
class GameScene: SKScene {
// Some code
}
在 MainMapScene.swift
中:
class MainMapScene: SKScene {
// Some code
}
但应用程序在启动时崩溃。控制台的输出显示:

所以看起来我的项目中某处仍然有对 GameScene
的引用,但我已经在整个项目范围内进行了搜索,但在任何地方都找不到 GameScene
.
我敢肯定这是一件非常简单的事情。我需要在 Storyboard 编辑器中更改导出或其他内容吗?我也可以通过尝试在新项目中更改 GameScene
的名称来重现此问题,因此我知道这不是我的项目所特有的。
最佳答案
GameScene
实际上在一个地方被引用,来自 NSKeyedArchiver
的错误应该提示您在哪里:它被编码在 .sks
您正在加载的文件。您可以在 Xcode 编辑器的 .sks
文件的“自定义类”选项卡中找到它。
此设置告诉 NSKeyedUnarchiver
当您加载 .sks
文件时编码场景应该是什么类。这应该是对 GameScene
的最后剩余引用,所以这应该完成您的重命名!
