如何调用aUIView.presentScene（aSKScene， transition： aSKTransition）以与aUIView.addSubview（aUITextField！）一致操作？

如何调用aUIView.presentScene（aSKScene， transition： aSKTransition）以与aUIView.addSubview一致操作。

没有过渡，就没有问题。与发生 1st 然后 – 不是统一的。SKTransitionUITextFieldSKTransition

就像，被种植在里面，坐在那里等待赶上UITextFieldviewViewControllerSKTransition

法典

func showScene(theSceneName: String) {

    if let ourScene = SKScene(fileNamed: theSceneName) {
                                    
        addTextFieldToVC(toSceneName: theSceneName)
        // NB: theSceneName is passed by Reference so we can
        //     return here before we call presentScene(...)
        addGamePiecesToScene(toScene: theSceneName)

        if let theView = self.view as! SKView? {
            theView.ignoresSiblingOrder = true
            theView.showsFPS = true
            theView.showsNodeCount = true
                
            // Finally, present the scene
            let theTransition = SKTransition.doorway(withDuration: 2.0)
            theView.presentScene(ourScene, transition: theTransition)
        }
            
    }   // if let ourScene
        
}   // showScene


func addTextFieldToVC(toSceneName: String) {

    if (toSceneName == "GameScene") {
        if let theView = self.view as! SKView? {
            aUITextField = UITextField(frame:CGRectMake(x: aXValue, y: aYValue))
            theView.addSubview(aUITextField!)
        }
    }

}


func addGamePiecesToScene(toScene: SKScene) {

    myRoom = SKSpriteNode(texture: SKTexture(imageNamed: roomImg))
    myRoom!.zPosition = roomZposition
    // etc with .size, .position
    toScene.addChild(myRoom!)

}

如上所示，我添加了 UITextField 1st，并添加了 SKSpriteNode 图像 2nd。

然而，它们与SKTransition并不同步。它们同步出现，只是没有 SKTransition。

FWIW，我已经尝试了这个序列，但没有变化：showScene

theView.presentScene(theSceneName, transition: theTransition)
DispatchQueue.main.async {
    addTextFieldToVC(toSceneName: theSceneName)
}

我也开始尝试使用完成处理程序：

override func viewDidLoad() {
        
    super.viewDidLoad()
                
    setupScene()
        
    // Completion Handler for showScene()
    showModifiedScene {
                 
        if thisSceneName == "GameScene" {  // a global var
            addTextFieldToVC(toSceneName: thisSceneName!)
        }
            
    }
     
}   // viewDidLoad


// modified for callback option??
func showScene(theSceneName: String) {

    if let ourScene = SKScene(fileNamed: theSceneName) {
                                    
        addGamePiecesToScene(toScene: ourScene)

        showModifiedScene()
            
    }   // if let ourScene
        
}   // showScene


func showModifiedScene(completionBlock: () -> Void) {

    if thisSceneName == "GameScene" {  // a global var
        if let ourScene = SKScene(fileNamed: thisSceneName!) {
            if let theView = self.view as! SKView? {
                theView.ignoresSiblingOrder = true
                theView.showsFPS = true
                theView.showsNodeCount = true
                    
                let theTransition = SKTransition.doorway(withDuration: 2.0)
                theView.presentScene(ourScene, transition: theTransition)
            }
        }

        completionBlock()
    }
                
}   // showModifiedScene

同样，没有过渡，就没有问题。与发生 1st 然后 – 不是统一的。SKTransitionUITextFieldSKTransition

我还在为这个而烦恼......但我认为是时候呼吁一些增援了！在等待髑髅地的时候，我仍然会工作。
