iOS 中的照相和照片功能如何實現呢？，其實非常容易，下面介紹如何使用 Camera 與 album 的存取：

首先在 info.plist 中打開以下兩個權限：

Privacy — Camera Usage Description：請求使用 Camera。
Privacy — Photo Library Usage Description：請求讀取 photo album

 func ShowAlbum() {
    // * 然後再下面設定相簿的來源和 delegate 
      let imagePicker = UIImagePickerController()
     imagePicker.sourceType = .photoLibrary
      imagePicker.delegate = self
    present(imagePicker, animated: true, completion: nil)
     }
   

   extension TripInfoViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
   //  * 繼承 UIImagePickerControllerDelegate、UINavigationControllerDelegate
       * 重點是 info[.originalImage]
    
       func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
       if let image = info[.originalImage] as? UIImage {
        coverImage.image = image
        self.dismiss(animated: false, completion: nil)
             }  
         }
    }
