这篇教程介绍如何在应用程序中进行拍摄照片，并将照片添加到APP中。
创建一个UIkit的框架项目

一、info.list

申请权限

Privacy - Camera Usage Description

二、代码

import UIKit

class ViewController: UIViewController { 
    @IBOutlet var imageView : UIImageView!
    @IBOutlet var button : UIButton!

    override func viewDidLoad() {
        super.viewDidLoad() 
        imageView.backgroundColor = .secondarySystemBackground 
        button.backgroundColor = .systemBlue
        button.setTitle("Take picture", for: .normal)
        button.setTitleColor(.white, for: .normal)
    }
    
    @IBAction func didTapButton(){
        let picker = UIImagePickerController()
        picker.sourceType = .camera
        picker.allowsEditing = true
        picker.delegate = self
        present(picker, animated: true)
    }


}
extension ViewController :UIImagePickerControllerDelegate,UINavigationControllerDelegate{
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    } 
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        picker.dismiss(animated: true, completion: nil)
        guard let image = info[UIImagePickerController.InfoKey.editedImage] as? UIImage else{
            return
        }  
        imageView.image = image
    }
}

三、main.storyboard

自行绑定

这样效果就出来了！
