如何使用Swift 4.2和Xcode 11.3将视频共享到instagram源？

import UIKit
import Photos
import MobileCoreServices

@IBAction func shareVideoButtonTapped(_ sender: UIButton) {
    let imagePickerController = UIImagePickerController()
    imagePickerController.sourceType = .photoLibrary
    imagePickerController.mediaTypes = [kUTTypeMovie as String]
    imagePickerController.delegate = self
    present(imagePickerController, animated: true, completion: nil)
}

extension ViewController: UIImagePickerControllerDelegate & UINavigationControllerDelegate {
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let videoURL = info[.mediaURL] as? URL {
            // 在这里可以对视频进行处理或编辑
            // ...
            
            // 调用Instagram应用程序来共享视频
            let instagramURL = URL(string: "instagram://library?AssetPath=\(videoURL.absoluteString)")
            if UIApplication.shared.canOpenURL(instagramURL!) {
                UIApplication.shared.open(instagramURL!, options: [:], completionHandler: nil)
            } else {
                // 如果用户设备上没有安装Instagram应用程序，可以提供一个备选方案
                // ...
            }
        }
        
        picker.dismiss(animated: true, completion: nil)
    }
}
