我正在制作一个类似“演示文稿”的游乐场，也就是说你可以添加幻灯片和点击按钮来前后移动。但是，我正在尝试使用SKTransition从scene1转到scene2，但转换会滚动我的标题和按钮。可以真的使用一些帮助，谢谢！
主要代码 -
import UIKit
import SpriteKit
import PlaygroundSupport
let frame = CGRect(x: 0, y: 0, width: 640, height: 480)
let view = SKView(frame: frame)
view.showsDrawCount = true
view.showsNodeCount = true
view.showsFPS = true
let scene = MainScene(size: CGSize(width: 640, height: 480))
view.presentScene(scene)
PlaygroundPage.current.liveView = view
MainScene.swift -
import UIKit
