使用图像拾取器将照片保存到2种不同的图像视图(swift3)

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    // ...
}

let imagePicker = UIImagePickerController()
imagePicker.delegate = self

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    // 获取选定的照片
    let selectedImage = info[.originalImage] as! UIImage
    
    // 将照片保存到第一个图像视图
    imageView1.image = selectedImage
    
    // 将照片保存到第二个图像视图
    imageView2.image = selectedImage
    
    // 关闭图像拾取器
    picker.dismiss(animated: true, completion: nil)
}

@IBAction func pickImage(_ sender: UIButton) {
    // 检查设备是否支持图像拾取器
    if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {
        // 设置图像拾取器的来源为相册
        imagePicker.sourceType = .photoLibrary
        
        // 显示图像拾取器
        present(imagePicker, animated: true, completion: nil)
    }
}
