iPhone X不尊重设置标签栏隐藏动画

Question

我有一个视图控制器被推送到标签栏控制器内的导航控制器上。视图控制器 hidesBottomBarWhenPushed 并且在视图上将出现它显示一个工具栏。无论我尝试什么，当视图控制器被推动或弹出时，它都不会停止动画工具栏向上/向下滑动。这似乎只是 iPhone X 上的一个问题。有谁知道如何解决它？

    class SafeAreaFixTabBar: UITabBar {

    var oldSafeAreaInsets = UIEdgeInsets.zero

    @available(iOS 11.0, *)
    override func safeAreaInsetsDidChange() {
        super.safeAreaInsetsDidChange()

        if oldSafeAreaInsets != safeAreaInsets {
            oldSafeAreaInsets = safeAreaInsets

            invalidateIntrinsicContentSize()
            superview?.setNeedsLayout()
            superview?.layoutSubviews()
        }
    }

    override func sizeThatFits(_ size: CGSize) -> CGSize {
        var size = super.sizeThatFits(size)
        if #available(iOS 11.0, *) {
            let bottomInset = safeAreaInsets.bottom
            if bottomInset > 0 && size.height < 50 && (size.height + bottomInset < 90) {
                size.height += bottomInset
            }
        }
        return size
    }

    override var frame: CGRect {
        get {
            return super.frame
        }
        set {
            var tmp = newValue
            if let superview = superview, tmp.maxY !=
                superview.frame.height {
                tmp.origin.y = superview.frame.height - tmp.height
            }

            super.frame = tmp
        }
    }
}
