    上面的是一张长图,不是视频,向左自动滚动。

    superview.frame: screen.bounds
    imageview.frame: screen.bounds.insets(x: -50, y: 0).offset(x: 50, y: 0)
    uiview.animate(duration: 60) { imageview.frame = imageview.frame.offset(x: 50, y: 0) }

    如果 swiftUI 开发的话原生代码就能实现

    ```swift
    import UIKit

    class ViewController: UIViewController {

    override func viewDidLoad() {
    super.viewDidLoad()

    let screenBounds = UIScreen.main.bounds

    let imageView = UIImageView(image: UIImage(named: "24110307_5"))
    view.addSubview(imageView)
    let imageW = screenBounds.width + 100
    imageView.frame = CGRect(x: 0, y: 0, width: imageW, height: screenBounds.height)


    //方式 1
    // UIView.animate(withDuration: 4) {
    // imageView.frame = CGRect(x: -100, y: 0, width: imageW, height: screenBounds.height)
    // } completion: { isFinished in
    // if isFinished{
    // print("结束")
    // }
    // }

    //方式 2:
    let animation = CABasicAnimation()
    animation.keyPath = "transform.translation.x"
    animation.fromValue = 0
    animation.toValue = -100
    animation.duration = 4
    animation.isRemovedOnCompletion= false
    animation.fillMode = .forwards
    imageView.layer.removeAllAnimations()
    imageView.layer.add(animation, forKey: nil)

    }

    }
    ```

    讲道理这里应该用动画或者放个视频吧,方便后台更换,原生实现可以但不太好。
