方案一：使用UIScrollView实现滑动效果

如果理解无误，您希望在点击“上一张”或“下一张”按钮时，能够实现卡片之间的滑动切换效果。为此，建议使用UIScrollView来实现这一功能。具体代码如下：

class FlashCardViewController: UIViewController, UIScrollViewDelegate {
    private let cOntents= ["Lorem", "Ipsum", "Dolor", "Sit"]
    private let scrollView = UIScrollView()
    private var currentIndex = 0
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupScrollView()
    }
    
    private func setupScrollView() {
        scrollView.delegate = self
        scrollView.isPagingEnabled = true
        scrollView.cOntentSize= CGSize(width: view.bounds.width * CGFloat(contents.count), height: view.bounds.height)
        
        for (index, content) in contents.enumerated() {
            let label = UILabel(frame: CGRect(x: view.bounds.width * CGFloat(index), y: 0, width: view.bounds.width, height: view.bounds.height))
            label.textAlignment = .center
            label.text = content
            scrollView.addSubview(label)
        }
        view.addSubview(scrollView)
    }
    
    @IBAction private func backButtonTapped(_ sender: Any) {
        guard currentIndex > 0 else { return }
        currentIndex -= 1
        let offset = CGPoint(x: view.bounds.width * CGFloat(currentIndex), y: 0)
        scrollView.setContentOffset(offset, animated: true)
    }
    
    @IBAction private func nextButtonTapped(_ sender: Any) {
        guard currentIndex
