Question

我正在为国际象棋制作一个计时器，我希望只要其中一方不玩，就会有模糊，但出于某种原因，下面的代码将模糊效果放在错误的位置，除非应用程序是从横向模式打开的：

var blackSeconds: Int = 0
var whiteSeconds: Int = 0

var blackTimer: Timer = Timer()
var whiteTimer: Timer = Timer()

let blurEffectViewForBlack = UIVisualEffectView(effect: UIBlurEffect(style: .dark))
let blurEffectViewForWhite = UIVisualEffectView(effect: UIBlurEffect(style: .dark))

override func viewDidLoad() {
    super.viewDidLoad()

    blackLabel.text = formatTime(time: blackSeconds)
    whiteLabel.text = formatTime(time: whiteSeconds)
    inputOutlet.attributedPlaceholder = NSAttributedString(
        string: "Enter number of seconds",
        attributes: [NSAttributedStringKey.foregroundColor: UIColor.lightGray]
    )

    let width: CGFloat = self.view.frame.size.width
    let height: CGFloat = self.view.frame.size.height

    print(width, height)

    blurEffectViewForBlack.frame = CGRect(x: 0, y: 0, width: width / 2, height: height)
    blurEffectViewForBlack.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    blurEffectViewForBlack.alpha = 0.9
    blurEffectViewForBlack.isHidden = true

    blurEffectViewForWhite.frame = CGRect(x: width / 2, y: 0, width: width / 2, height: self.view.bounds.height)
    blurEffectViewForWhite.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    blurEffectViewForWhite.alpha = 0.9
    blurEffectViewForWhite.isHidden = true

    view.addSubview(blurEffectViewForBlack)
    view.addSubview(blurEffectViewForWhite)
}

我担心这与self.view.frame.size根据方向不会改变这一事实有关。请注意，我还尝试了self.view.bounds，它产生了相同的结果。见here。

为什么我的CGRect的界限很尴尬？
