Swift图像从帧的底部到顶部显示动画(擦除动画)

import UIKit

class ViewController: UIViewController {
    
    let imageView = UIImageView(image: UIImage(named: "yourImage"))
    let overlayView = UIView()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置 imageView 和 overlayView
        imageView.frame = CGRect(x: 0, y: view.bounds.height, width: view.bounds.width, height: 200)
        overlayView.frame = imageView.frame
        overlayView.backgroundColor = .black
        
        // 添加到视图
        view.addSubview(imageView)
        view.addSubview(overlayView)
        
        // 动画
        UIView.animate(withDuration: 2.0, delay: 0, options: .curveEaseInOut, animations: {
            self.imageView.frame.origin.y = self.view.bounds.height - 200
            self.overlayView.frame.origin.y = self.view.bounds.height
        }, completion: { _ in
            self.overlayView.removeFromSuperview()
        })
    }
}
