在iOS中同时使用相机和照片库

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    @IBAction func openCameraAndPhotoLibrary(_ sender: UIButton) {
        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = .camera
        imagePicker.mediaTypes = [kUTTypeImage as String]
        imagePicker.allowsEditing = false
        present(imagePicker, animated: true, completion: nil)
    }
    
    // 拍照或选择照片完成后的回调方法
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            // 处理选择的照片
            // ...
        }
        dismiss(animated: true, completion: nil)
    }
    
    // 取消拍照或选择照片后的回调方法
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        dismiss(animated: true, completion: nil)
    }
}
