今天介紹如何開啟手機的相簿使用的照片

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    func presentImagePicker() {
        if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
            let imagePicker = UIImagePickerController()
            imagePicker.sourceType = .photoLibrary
            imagePicker.delegate = self
            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let pickedImage = info[.originalImage] as? UIImage {
            // 獲取到圖片
            // 這裡可以將圖片顯示在 UI 中或進行其他處理
        }
        dismiss(animated: true, completion: nil)
    }

    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        dismiss(animated: true, completion: nil)
    }
}

透過選取相簿裡的照片可以跟非常多東西互動可以動手玩看看
