所以，目前我有一个游戏，我用 sprite kit 制作并使用这种方式让所有东西都适合屏幕尺寸:

buyButton = SKSpriteNode(texture: SKTexture(imageNamed: "BuyButton"), color: .clear, size: CGSize(width: frame.maxX / 2.9, height: frame.maxY / 10))
buyButton.position = CGPoint(x:-frame.maxX + frame.midX*2, y: -frame.maxY + frame.midY*1.655)
addChild(buyButton)

如您所见，它使用框架来计算宽度和高度以及节点在场景中的位置，这适用于我从 6s 到 8 Plus 一直使用的所有屏幕尺寸。 但是当谈到 iPhone X 时，它就出现了问题。与 iPhone 8 Plus 相比，它似乎拉伸(stretch)了一切，因为屏幕尺寸更大且形状奇特，如下图所示

我一直在寻找这个问题的解决方案，但没有一个真正有帮助，甚至只是使它变得更糟，我无法理解如何以编程方式在我的 sprite 工具包项目中使用安全区域布局，就像在这个解决方案中一样 here

我的问题是

我如何才能让所有东西都适合 iPhone X 的屏幕，使其适合而不是切断乐谱标签和我在右上角的东西？

itemDescriptionLabel = UILabel(frame: CGRect(x: frame.maxX - 150, y: frame.maxY - 130 , width: frame.maxX / 0.7, height: frame.maxY / 3.5))
itemDescriptionLabel.font = UIFont(name: "SFCompactRounded-Light", size: 17)
itemDescriptionLabel.text = "This purchase stops all the popup ads that happen after a certain amount of time playing the game from showing up."
itemDescriptionLabel.numberOfLines = 4
itemDescriptionLabel.adjustsFontSizeToFitWidth = true
self.scene?.view?.addSubview(itemDescriptionLabel)

let safeAreaInsets = yourSpriteKitView.safeAreaInsets;
buyButton.position = CGPoint(x:safeAreaInsets.left - frame.maxX + frame.midX*2, y: safeAreaInsets.top - frame.maxY + frame.midY*1.655)

screenWidth = self.view!.bounds.width
screenHeight = self.view!.bounds.height

coinScoreLabel = Score(num: 0,color: UIColor(red:1.0, green: 1.0, blue: 0.0, alpha: 1), size: 50, useFont: "SFCompactRounded-Heavy" )  // UIColor(red:1.00, green:0.81, blue:0.07, alpha:1.0)
coinScoreLabel.name = "coinScoreLabel"
coinScoreLabel.horizontalAlignmentMode = .right
//coinScoreLabel.verticalAlignmentMode = .top
coinScoreLabel.position = CGPoint(x: screenWidth / 2.02, y: inset.top - screenHeight / 2.02)
coinScoreLabel.zPosition = 750
addChild(coinScoreLabel)

我在我拥有的另一个 SpriteNode 上尝试过它，例如下面的这个，它适用于我不知道为什么 yellow label 会这样做。

 playButton = SKSpriteNode(texture: SKTexture(imageNamed: "GameOverMenuPlayButton"), color: .clear, size: CGSize(width: 120, height: 65))
 playButton.position = CGPoint(x: inset.right - frame.midX, y: inset.bottom + frame.minY + playButton.size.height / 1.7)
 playButton.zPosition = 1000
 deathMenuNode.addChild(playButton) 

结果是这样的，很完美:

最佳答案

有趣的问题。当我们试图将我们的 View “转换”为SKView 以创建我们的游戏场景时，问题就出现了。本质上，我们可以拦截那个时刻(使用 viewWillLayoutSubviews 而不是 viewDidLoad)并根据 safeAreaLayoutGuide 转换 View 框架。布局框架属性。

一些代码作为例子:

游戏 View Controller :

class GameViewController: UIViewController {
    override func viewWillLayoutSubviews() {
        super.viewWillLayoutSubviews()
        if #available(iOS 11.0, *), let view = self.view {
           view.frame = self.view.safeAreaLayoutGuide.layoutFrame
        }  
        guard let view = self.view as! SKView? else { return }
        view.ignoresSiblingOrder = true
        view.showsFPS = true
        view.showsNodeCount = true
        view.showsPhysics = true
        view.showsDrawCount = true
        let scene = GameScene(size:view.bounds.size)
        scene.scaleMode = .aspectFill
        view.presentScene(scene)
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        print("---")
        print("∙ \(type(of: self))")
        print("---")
    }
}

游戏场景:

class GameScene: SKScene {
    override func didMove(to view: SKView) {
        print("---")
        print("∙ \(type(of: self))")
        print("---")
        let labLeftTop = SKLabelNode.init(text: "LEFTTOP")
        labLeftTop.horizontalAlignmentMode = .left
        labLeftTop.verticalAlignmentMode = .top
        let labRightTop = SKLabelNode.init(text: "RIGHTTOP")
        labRightTop.horizontalAlignmentMode = .right
        labRightTop.verticalAlignmentMode = .top
        let labLeftBottom = SKLabelNode.init(text: "LEFTBTM")
        labLeftBottom.horizontalAlignmentMode = .left
        labLeftBottom.verticalAlignmentMode = .bottom
        let labRightBottom = SKLabelNode.init(text: "RIGHTBTM")
        labRightBottom.horizontalAlignmentMode = .right
        labRightBottom.verticalAlignmentMode = .bottom
        self.addChild(labLeftTop)
        self.addChild(labRightTop)
        self.addChild(labLeftBottom)
        self.addChild(labRightBottom)
        labLeftTop.position = CGPoint(x:0,y:self.frame.height)
        labRightTop.position = CGPoint(x:self.frame.width,y:self.frame.height)
        labLeftBottom.position = CGPoint(x:0,y:0)
        labRightBottom.position = CGPoint(x:self.frame.width,y:0)
    }
}

其他方式:

另一种只获取安全区域布局框架和当前 View 框架之间的差异而不通过 viewWillLayoutSubviews 来启动我们的场景的方法可能是使用协议(protocol)。

P.S.:在下方，我报告了一张引用图片，您可以在其中看到不同尺寸:

• 主屏幕高度(我们的 View 高度)
• 安全区
• 状态栏高度(在顶部，iPhone X 为 44 像素)

游戏 View Controller :

protocol LayoutSubviewDelegate: class {
    func safeAreaUpdated()
}
class GameViewController: UIViewController {
    weak var layoutSubviewDelegate:LayoutSubviewDelegate?
    override func viewWillLayoutSubviews() {
        super.viewWillLayoutSubviews()
        if let _ = self.view {
           layoutSubviewDelegate?.safeAreaUpdated()
        }
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        print("---")
        print("∙ \(type(of: self))")
        print("---")
        guard let view = self.view as! SKView? else { return }
        view.ignoresSiblingOrder = true
        view.showsFPS = true
        view.showsNodeCount = true
        view.showsPhysics = true
        view.showsDrawCount = true
        let scene = GameScene(size:view.bounds.size)
        scene.scaleMode = .aspectFill
        view.presentScene(scene)
    }
}

游戏场景:

class GameScene: SKScene,LayoutSubviewDelegate {
    var labLeftTop:SKLabelNode!
    var labRightTop:SKLabelNode!
    var labLeftBottom:SKLabelNode!
    var labRightBottom:SKLabelNode!
    func safeAreaUpdated() {
        if let view = self.view {
            let top = view.bounds.height-(view.bounds.height-view.safeAreaLayoutGuide.layoutFrame.height)+UIApplication.shared.statusBarFrame.height
            let bottom = view.bounds.height - view.safeAreaLayoutGuide.layoutFrame.height-UIApplication.shared.statusBarFrame.height
            refreshPositions(top: top, bottom: bottom)
        }
    }
    override func didMove(to view: SKView) {
        print("---")
        print("∙ \(type(of: self))")
        print("---")
        if let view = self.view, let controller = view.next, controller is GameViewController {
            (controller as! GameViewController).layoutSubviewDelegate = self
        }
        labLeftTop = SKLabelNode.init(text: "LEFTTOP")
        labLeftTop.horizontalAlignmentMode = .left
        labLeftTop.verticalAlignmentMode = .top
        labRightTop = SKLabelNode.init(text: "RIGHTTOP")
        labRightTop.horizontalAlignmentMode = .right
        labRightTop.verticalAlignmentMode = .top
        labLeftBottom = SKLabelNode.init(text: "LEFTBTM")
        labLeftBottom.horizontalAlignmentMode = .left
        labLeftBottom.verticalAlignmentMode = .bottom
        labRightBottom = SKLabelNode.init(text: "RIGHTBTM")
        labRightBottom.horizontalAlignmentMode = .right
        labRightBottom.verticalAlignmentMode = .bottom
        self.addChild(labLeftTop)
        self.addChild(labRightTop)
        self.addChild(labLeftBottom)
        self.addChild(labRightBottom)
        labLeftTop.position = CGPoint(x:0,y:self.frame.height)
        labRightTop.position = CGPoint(x:self.frame.width,y:self.frame.height)
        labLeftBottom.position = CGPoint(x:0,y:0)
        labRightBottom.position = CGPoint(x:self.frame.width,y:0)
    }
    func refreshPositions(top:CGFloat,bottom:CGFloat){
        labLeftTop.position = CGPoint(x:0,y:top)
        labRightTop.position = CGPoint(x:self.frame.width,y:top)
        labLeftBottom.position = CGPoint(x:0,y:bottom)
        labRightBottom.position = CGPoint(x:self.frame.width,y:bottom)
    }
}

输出:

子类化方法:

另一种在不触及当前类代码的情况下获得正确安全区域尺寸的方法可以使用一些子类，因此对于我们的 GameViewController 我们将其设置为 GameController 并且对于 GameScene，我们可以将其设置为 GenericScene，如下例所示:

游戏 View Controller :

class GameViewController: GameController {
    override func viewDidLoad() {
        super.viewDidLoad()
        guard let view = self.view as! SKView? else { return }
        view.ignoresSiblingOrder = true
        let scene = GameScene(size:view.bounds.size)
        scene.scaleMode = .aspectFill
        view.presentScene(scene)
    }
}
protocol LayoutSubviewDelegate: class {
    func safeAreaUpdated()
}
class GameController:UIViewController {
    weak var layoutSubviewDelegate:LayoutSubviewDelegate?
    override func viewWillLayoutSubviews() {
        super.viewWillLayoutSubviews()
        if let _ = self.view {
            layoutSubviewDelegate?.safeAreaUpdated()
        }
    }
}

游戏场景:

class GameScene: GenericScene {
    override func safeAreaUpdated() {
        super.safeAreaUpdated()
        if let view = self.view {
            let insets = view.safeAreaInsets
            // launch your code to update positions here
        }
    }
    override func didMove(to view: SKView) {
        super.didMove(to: view)
        // your stuff
    }
}
class GenericScene: SKScene, LayoutSubviewDelegate {
    func safeAreaUpdated(){}
    override func didMove(to view: SKView) {
        if let view = self.view, let controller = view.next, controller is GameViewController {
            (controller as! GameViewController).layoutSubviewDelegate = self
        }
    }
}
