ios - 使用 SpriteKit 传递多个数组 - UIColor 和 String

Question

我有三个数据 View Controller :settingsVC.swift、menuVC.swift 和 GameScene.swift

我正在尝试使用prepareforsegue方法将[UIColor]和[String]数组从设置传输到menuVC，然后使用instantiateViewController从menuVC到GameScene.swift的另一次传输。我已在每个数组中声明了空数组，只想将数据从一页传递到另一页，并且在我的两个数组上都收到“使用未解析的标识符”。如有任何帮助，我们将不胜感激。

class MenuVC: UIViewController {

var colourSettingsMenu = [UIColor]()
var otherSettingsMenu = [String]()

//action function for button to transfer to a 1 player game
@IBAction func Player1Game(_ sender: MenuVC) {
    moveToGame(game: .player1, colourSettings: colourSettingsMenu, otherSettings: otherSettingsMenu)
}

//action function for button to transfer to a 2 player game
@IBAction func Player2Game(_ sender: MenuVC) {
    moveToGame(game: .player2, colourSettings: colourSettingsMenu, otherSettings: otherSettingsMenu)
}


func moveToGame(game : gameType, colourSettings: [UIColor], otherSettings: [String]) {
    let GameVC = self.storyboard?.instantiateViewController(withIdentifier: "GameVC") as! GameViewController

    currentGameType = game
    colourSettingsGame.GameVC = colourSettings;
    otherSettingsGame.GameVC = otherSettings;
    self.navigationController?.pushViewController(GameVC, animated: true)
}

@IBAction func moveToSettings(_ sender: Any) {
    performSegue(withIdentifier: "settings", sender: self)

}

override func prepare(for segue: UIStoryboardSegue, sender:Any?) {
    if (segue.identifier == "settings") {
        let SettingsVC = segue.destination as! SettingsVC
        SettingsVC.colourSettings = colourSettingsMenu
        SettingsVC.otherSettings = otherSettingsMenu
    }

}

}

class SettingsVC : UIViewController {

//Colours for segue transfer
var player1Colour: UIColor?
var player2Colour: UIColor?
var ballColour: UIColor?

// other settings to allow segue transfer
// do we need these
var AIDiff: String?
var paddleSi: String?
var ballSi: String?

//arrays for segue transfer
var colourSettings = [UIColor]()
var otherSettings = [String]()

override func prepare(for segue: UIStoryboardSegue, sender:Any?) {
    let colourSettings = [player1Colour, player2Colour, ballColour]
    let otherSettings = [AIDiff, paddleSi, ballSi]

    if (segue.identifier == "back") {
        let MenuVC = segue.destination as! MenuVC
        MenuVC.colourSettingsMenu = colourSettings as! [UIColor]
        MenuVC.otherSettingsMenu = otherSettings as! [String]
    }

}

class GameScene: SKScene {

 // init colour settings array
 var colourSettingsGame = [UIColor]()
 // init other settings array
 var otherSettingsGame = [String]()

 var currentGameType = gameType?.self
 }

Answer 1

这里你不应该像类名一样命名变量

override func prepare(for segue: UIStoryboardSegue, sender:Any?) {
if (segue.identifier == "settings") {
      let nextSettings = segue.destination as! SettingsVC
      nextSettings.colourSettings = colourSettingsMenu
      nextSettings.otherSettings = otherSettingsMenu
  }

}

这里

override func prepare(for segue: UIStoryboardSegue, sender:Any?) {
   let colourSettings = [player1Colour, player2Colour, ballColour]
   let otherSettings = [AIDiff, paddleSi, ballSi]

  if (segue.identifier == "back") {
     let nexrMenu = segue.destination as! MenuVC
     nexrMenu.colourSettingsMenu = colourSettings as! [UIColor]
     nexrMenu.otherSettingsMenu = otherSettings as! [String]
 }
