【问题描述】：
我正在尝试将iCarousel 添加到我的游戏中，该iCarousel 将显示在 MainMenu 中，您可以在游戏中选择一个项目并解锁其他项目并在游戏中取得更多进展。
尝试查看一些教程，但我仍然有一些问题，我无法弄清楚。
但是“SpriteKit iCarousel”github 上的结构也与我的不同。
我可以让轮播显示出来但甚至不起作用，并且由于某种原因也像“卡住”一样位于屏幕的左上角。
这是我的 GameViewController.swift 代码：
import UIKit
import SpriteKit
import GameKit
class GameViewController: UIViewController, iCarouselDataSource, iCarouselDelegate {
var imageArray: NSMutableArray = NSMutableArray()
var selectedIndex: Int!
var carousel : iCarousel!
deinit{
NSNotificationCenter.defaultCenter().removeObserver(self)
}
func showCarousel(){
carousel.hidden = false
}
func hideCarousel(){
carousel.hidden = true
}
override func awakeFromNib(){
super.awakeFromNib()
self.imageArray = NSMutableArray(array: ["white","white2","white3"])
}
func carousel(carousel:iCarousel, didSelectItemAtIndex index:NSInteger) {
let scene = MenuScene(size:self.view.bounds.size)
scene.imageName = self.imageArray[index] as! String
self.hideCarousel()
}
override func viewDidLoad() {
super.viewDidLoad()
self.authenticateLocalPlayer()
self.setupCarousel()
}
func setupCarousel() {
carousel = iCarousel()
carousel.dataSource = self
carousel.delegate = self
carousel.type = .Linear
carousel.reloadData()
let spriteKitView = SKView()
spriteKitView.frame = CGRectMake(0, 0, 250, 250)
// self.view.insertSubview(spriteKitView, belowSubview: self.carousel) // this is showing an empty gray box
self.view.addSubview(self.carousel)
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.showCarousel), name: "showBallPicker", object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.hideCarousel), name: "hideBallPicker", object: nil)
}
func carousel(carousel: iCarousel, valueForOption option: iCarouselOption, withDefault value: CGFloat) -> CGFloat{
if (option == .Spacing){
return value * 2
}
return value
}
func carousel(carousel: iCarousel, viewForItemAtIndex index: Int, reusingView view: UIView?) -> UIView {
var imageView: UIImageView!
if view == nil {
imageView = UIImageView(frame: CGRectMake(0, 0, 250, 250))
imageView.backgroundColor = UIColor.redColor()
imageView.contentMode = .ScaleAspectFill
}else{
imageView = view as! UIImageView
}
imageView.image = UIImage(named: "\(imageArray.objectAtIndex(index))")
return imageView
}
func numberOfItemsInCarousel(carousel: iCarousel) -> Int {
return imageArray.count
}
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
let skView = self.view as! SKView
if skView.scene == nil {
skView.showsFPS = true
skView.showsNodeCount = true
skView.showsPhysics = false
skView.multipleTouchEnabled = true
let menuScene = MenuScene(size: CGSizeMake(375,667))
menuScene.scaleMode = .AspectFill
menuScene.imageName = self.imageArray[0] as! String
self.hideCarousel()
skView.presentScene(menuScene)
}
}
override func viewWillDisappear(animated: Bool) {
if let skView = self.view as? SKView {
skView.presentScene(nil)
}
}
override func viewDidDisappear(animated: Bool) {
if let skView = self.view as? SKView {
skView.presentScene(nil)
}
}
override func prefersStatusBarHidden() -> Bool {
return true
}
}
这就是我在 MenuScene.swift
上所做的var childNode = SKSpriteNode()
var imageName = "white"{
didSet{
self.childNode.texture = SKTexture(imageNamed: imageName)
}
}
func showBallPicker(){
NSNotificationCenter.defaultCenter().postNotificationName("showBallPicker", object: nil)
}
override init(size: CGSize) {
// here im supposed to create a childNode SKSpriteNode, but for what? it only adds the same image of the carousel and that's it.
self.childNode = SKSpriteNode(imageNamed: imageName)
self.childNode.anchorPoint = CGPointZero
self.childNode.zPosition = 30
self.childNode.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
self.addChild(self.childNode)
}
然后，在 touchesEnded 时，我从一个按钮 touch self.showBallPicker() 调用以显示轮播。
正如我之前所说，它正在添加轮播，但甚至无法正常工作并且位于左上角。
我怎样才能做到这一点？一旦我可以让它正确显示，我就可以处理其余的了。
谢谢。
