从右到左 Segue，无需推送或呈现 ViewController

Question

是否有可能在没有 push or Persenting ViewController 的情况下从 Right To Left 执行 segue。以下代码可以很好地处理动画，但如果我使用此 class，我的 TabBar 将被隐藏。如果我删除 Perform() 中的代码 TabBar 显示但动画停止使用 MDCBottomNavigationBar

class SegueFromRight: UIStoryboardSegue {
    override func perform() {
        let src = self.source
        let dst = self.destination
        src.view.superview?.insertSubview(dst.view, aboveSubview: src.view)

        dst.view.transform = CGAffineTransform(translationX: src.view.frame.size.width, y: 0)

        UIView.animate(withDuration: 0.25,delay: 0.0,options: UIView.AnimationOptions.curveEaseInOut,animations: {
            dst.view.transform = CGAffineTransform(translationX: 0, y: 0)
        },completion: { finished in
            src.navigationController?.pushViewController(dst, animated: false)
        }
        )
    }
}

有没有其他方法可以在不隐藏的情况下使用动画执行 segue TabBar？

Answer 1

试试这个

private func setupAlwaysVisibleView() {
        guard let tabBarController = self.tabBarController else { return }

        tabBarController.view.insertSubview(alwaysVisibleView, belowSubview: tabBarController.tabBar)
    }

Answer 2

终于找到答案了。只需删除行 Push ViewController

class SegueFromRight: UIStoryboardSegue {
    override func perform() {
        let src = self.source
        let dst = self.destination
        src.view.superview?.insertSubview(dst.view, aboveSubview: src.view)

        dst.view.transform = CGAffineTransform(translationX: src.view.frame.size.width, y: 0)

        UIView.animate(withDuration: 0.25,delay: 0.0,options: UIView.AnimationOptions.curveEaseInOut,animations: {
            dst.view.transform = CGAffineTransform(translationX: 0, y: 0)
        },completion: { finished in
            //Remove Following line if you want to segue modally  
            //src.navigationController?.pushViewController(dst, animated: false)
        }
        )
    }
}
