iOS Swift -使用UIImagePickerController自动保存视频

import UIKit
import MobileCoreServices

let imagePicker = UIImagePickerController()
imagePicker.delegate = self

imagePicker.sourceType = .camera
imagePicker.mediaTypes = [kUTTypeMovie as String]

extension ViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let videoURL = info[.mediaURL] as? URL {
            // 在这里处理视频URL，可以进行保存操作
            // 例如使用FileManager将视频保存到指定路径
            let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
            let destinationURL = documentsDirectory.appendingPathComponent("video.mp4")
            do {
                try FileManager.default.moveItem(at: videoURL, to: destinationURL)
                print("视频保存成功：\(destinationURL)")
            } catch {
                print("视频保存失败：\(error)")
            }
        }
        picker.dismiss(animated: true, completion: nil)
    }
}
