Question

在iPhone X上运行时，视图上的对象与在其他设备（如iPhone 6）上运行时的位置不同。
例如，在这张照片中，当我在iPhone 6s上运行时，绿色和青色视图与背景图像的白色三角形几乎在y位置。但是，当在iPhone X上运行时，这两个视图比白色三角形看起来更靠上。

当我在iPhone X上运行时，我希望使对象在其他设备上的位置相同。
我怎么解决这个问题？您是否有更好的想法来调整布局？

class Constants {

    //width of base design size
    static let guiPartsWidthOnDesign = CGFloat(750.0)

    //ratio for layout
    static var guiPartsMultiplier: CGFloat = UIScreen.main.bounds.width / (Constants.guiPartsWidthOnDesign / 2.0)

    //detect safe area
    static let safeArea = UIApplication.shared.delegate?.window??.safeAreaInsets.bottom

}

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        self.view.frame = CGRect(x: 0,
                                 y: 0,
                                 width: self.view.frame.size.width,
                                 height: self.view.frame.size.height)

        //backgrond
        let background = UIImageView.init(frame: UIScreen.main.bounds)
        background.center.x = self.view.frame.size.width/2
        background.image = UIImage(named:"BG")
        background.contentMode = UIViewContentMode.scaleAspectFill
        self.view.insertSubview(background, at: 0)

        //downleft blue button
        let blueButton = UIImageView.init(frame: CGRect(
            x: 64/2*Constants.guiPartsMultiplier,
            y: self.view.frame.size.height-(52/2+34/2)*Constants.guiPartsMultiplier-Constants.safeArea!,
            width: 60/2*Constants.guiPartsMultiplier,
            height: 52/2*Constants.guiPartsMultiplier))
        self.view.addSubview(blueButton)
        blueButton.backgroundColor = UIColor.blue

        self.view.addSubview(greenButton)
        greenButton.backgroundColor = UIColor.green

        //cyan button
        let cyanButton = UIImageView.init(frame: CGRect(
            x: (64/2+(60/2)*2+(128/2*2))*Constants.guiPartsMultiplier,
            y: self.view.frame.size.height-(52/2+34/2)*Constants.guiPartsMultiplier-Constants.safeArea!,
            width: 60/2*Constants.guiPartsMultiplier,
            height: 52/2*Constants.guiPartsMultiplier))
        self.view.addSubview(cyanButton)
        cyanButton.backgroundColor = UIColor.cyan

        //4 blue buttons
        for i in 1..<5 {
            let subBlueButton = UIImageView.init(frame: CGRect(
                x: 64/2*Constants.guiPartsMultiplier,
                y: self.view.frame.size.height-((43.0+CGFloat(50*i))*Constants.guiPartsMultiplier)-Constants.safeArea!,
                width: 60/2*Constants.guiPartsMultiplier,
                height: 52/2*Constants.guiPartsMultiplier))
            self.view.addSubview(subBlueButton)
            subBlueButton.alpha = 1.0
            subBlueButton.backgroundColor = UIColor.blue
        }

        //down bar
        let bar = UIImageView.init(frame: CGRect(
            x:0,
            y: self.view.frame.size.height-50,
            width: self.view.frame.size.width,
            height: 50))
        bar.alpha = 0.3
        bar.backgroundColor = UIColor.blue
        self.view.addSubview(bar)

        print("Constants: \(UIScreen.main.bounds.size.width, Constants.guiPartsWidthOnDesign, Constants.guiPartsMultiplier)")
        print("SafeArea: \(String(describing: Constants.safeArea))")
        print("Height: \(UIScreen.main.bounds.size.height)")

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

您需要在情节提要中或使用视觉格式语言的代码中使用自动版式。

AutoLayout的目标是完全按照您的要求进行操作。

对象的外观不同，取决于iOS中的设备
