在Swift中使用imagePickerController在同一视图控制器中select两个不同的图像

我正在做一个应用程序，其中有两个UIImageViews。 在每个图像视图中，用户需要能够input不同的图像。 这是我到目前为止的代码。

var imagePicker = UIImagePickerController() @IBAction func chooseImage1(sender: AnyObject) { if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum){ println("Button capture") imagePicker.delegate = self imagePicker.sourceType = .SavedPhotosAlbum imagePicker.allowsEditing = false self.presentViewController(imagePicker, animated: true, completion: nil) } } @IBAction func chooseImage2(sender: AnyObject) { if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum){ println("Button capture") imagePicker2.delegate = self imagePicker2.sourceType = .SavedPhotosAlbum imagePicker2.allowsEditing = false self.presentViewController(imagePicker, animated: true, completion: nil) } } func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) { let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage chooseImage1.image = pickedImage let pickedImage2 = info[UIImagePickerControllerOriginalImage] as? UIImage chooseImage2.image = pickedImage2 dismissViewControllerAnimated(true, completion: nil) } func imagePickerControllerDidCancel(picker: UIImagePickerController) { dismissViewControllerAnimated(true, completion: nil) } 

这最终会为每个不同的图像视图select相同的图像。 我希望能够select两个单独的照片，每个视图一个。 感谢您的帮助。

您可以设置每个button一个不同的标签，并根据button的标签更新一个imageView或其他。 你只需要一个UIImagePickerController：

更新： Xcode 8.3.1•Swift 3.1

 import UIKit class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate { @IBOutlet weak var imageView1: UIImageView! @IBOutlet weak var imageView2: UIImageView! var imagePicker = UIImagePickerController() var imagePicked = 0 override func viewDidLoad() { super.viewDidLoad() imagePicker.delegate = self imagePicker.sourceType = .savedPhotosAlbum imagePicker.allowsEditing = false } @IBAction func chooseImage1(_ sender: UIButton) { if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.savedPhotosAlbum){ imagePicked = sender.tag present(imagePicker, animated: true) } } func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage if imagePicked == 1 { imageView1.image = pickedImage } else if imagePicked == 2 { imageView2.image = pickedImage } dismiss(animated: true) } func imagePickerControllerDidCancel(_ picker: UIImagePickerController) { dismiss(animated: true) } }
