通过UIImagepickerController从摄像头中拾取图片并保存到ios相册中后，获取图片名称

import UIKit
import Photos

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    
    let imagePicker = UIImagePickerController()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        imagePicker.delegate = self
        imagePicker.sourceType = .camera
    }
    
    @IBAction func pickImageFromCamera(_ sender: UIButton) {
        present(imagePicker, animated: true, completion: nil)
    }
    
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let pickedImage = info[.originalImage] as? UIImage {
            UIImageWriteToSavedPhotosAlbum(pickedImage, self, #selector(image(_:didFinishSavingWithError:contextInfo:)), nil)
        }
        
        dismiss(animated: true, completion: nil)
    }
    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        dismiss(animated: true, completion: nil)
    }
    
    @objc func image(_ image: UIImage, didFinishSavingWithError error: Error?, contextInfo: UnsafeRawPointer) {
        if let error = error {
            print("保存图片到相册失败：\(error.localizedDescription)")
        } else {
            // 获取保存到相册中的图片名称
            let fetchOptions = PHFetchOptions()
            fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
            
            let fetchResult = PHAsset.fetchAssets(with: .image, options: fetchOptions)
            if let asset = fetchResult.firstObject {
                let assetResources = PHAssetResource.assetResources(for: asset)
                if let filename = assetResources.first?.originalFilename {
                    print("保存到相册的图片名称：\(filename)")
                }
            }
        }
    }
