ios - Selección de dos imágenes diferentes en el mismo controlador de vista usando imagePickerController en Swift

uiimageview uiimagepickercontroller

Question

Estoy haciendo una aplicación en la que hay dos UIImageViews. En cada vista de imagen, el usuario debe poder ingresar una imagen diferente. Aquí está el código que tengo hasta ahora.

    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)
}

Esto termina eligiendo la misma imagen para cada vista de imagen diferente. Me gustaría poder elegir dos fotos individuales, una para cada vista. Gracias por tu ayuda.

Puede configurar una etiqueta diferente para cada botón y, según la etiqueta del botón, actualice una imagen Vista u otra. Solo necesita un UIImagePickerController:

actualización: 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)
    }
}
