ios - 在堆栈 View 中调整 UIButtons 中的文本大小

Question

我正在根据 viewDidLoad 上的设备宽度调整 4 个相同类型按钮中的文本大小。它们处于水平堆栈 View 中。有什么方法可以更优雅地做到这一点？

// resize main buttons
        let screenSize = UIScreen.main.bounds
        let screenWidth = screenSize.width

        if screenWidth <= 320 {
            mainLockButton.titleLabel?.font = UIFont.systemFont(ofSize: 12, weight: .medium)
            mainUnlockButton.titleLabel?.font = UIFont.systemFont(ofSize: 12, weight: .medium)
            mainSplitButton.titleLabel?.font = UIFont.systemFont(ofSize: 12, weight: .medium)
            mainRoundButton.titleLabel?.font = UIFont.systemFont(ofSize: 12, weight: .medium)
        } else if screenWidth <= 375 {
            mainLockButton.titleLabel?.font = UIFont.systemFont(ofSize: 13, weight: .medium)
            mainUnlockButton.titleLabel?.font = UIFont.systemFont(ofSize: 13, weight: .medium)
            mainSplitButton.titleLabel?.font = UIFont.systemFont(ofSize: 13, weight: .medium)
            mainRoundButton.titleLabel?.font = UIFont.systemFont(ofSize: 13, weight: .medium)
        } else {
            mainLockButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
            mainUnlockButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
            mainSplitButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
            mainRoundButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
        }

不完美，但看起来好多了

  let screenWidth = UIScreen.main.bounds.width
  let buttons = [mainLockButton, mainUnlockButton, mainSplitButton, mainRoundButton]

  buttons.forEach {
    if screenWidth <= 320 {
        $0.titleLabel?.font = UIFont.systemFont(ofSize: 12, weight: .medium)
    } else if screenWidth <= 375 {
        $0.titleLabel?.font = UIFont.systemFont(ofSize: 13, weight: .medium)
    } else {
        $0.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)
    }
  }
