再次尝试拖动时，iOS UIImageView CGAffinetranform平移手势可将UIImage视图恢复为标识

import UIKit

class ViewController: UIViewController {
    var imageView: UIImageView!
    var originalTransform: CGAffineTransform!

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建UIImageView并设置图像
        imageView = UIImageView(image: UIImage(named: "your_image_name"))
        imageView.frame = CGRect(x: 100, y: 100, width: 200, height: 200)
        view.addSubview(imageView)
        
        // 添加平移手势识别器
        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePan(_:)))
        imageView.addGestureRecognizer(panGesture)
        imageView.isUserInteractionEnabled = true
        
        // 保存原始的transform属性
        originalTransform = imageView.transform
    }
    
    @objc func handlePan(_ gesture: UIPanGestureRecognizer) {
        let translation = gesture.translation(in: view)
        
        // 将平移距离应用于UIImageView的transform属性
        imageView.transform = CGAffineTransform(translationX: translation.x, y: translation.y)
        
        if gesture.state == .ended {
            // 手势结束时，重置transform属性为原始状态
            imageView.transform = originalTransform
        }
    }
}
