UIImageView拖放到另一个

// 创建一个UIImageView对象
let imageView = UIImageView(image: UIImage(named: "image.png"))
imageView.frame = CGRect(x: 100, y: 100, width: 100, height: 100)

// 添加拖动手势识别器
let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePanGesture(_:)))
imageView.addGestureRecognizer(panGesture)

// 将UIImageView添加到视图中
self.view.addSubview(imageView)

// 拖动手势的回调方法
@objc func handlePanGesture(_ gesture: UIPanGestureRecognizer) {
    let translation = gesture.translation(in: self.view)
    gesture.view?.center = CGPoint(x: gesture.view!.center.x + translation.x, y: gesture.view!.center.y + translation.y)
    gesture.setTranslation(CGPoint.zero, in: self.view)
}
