Use UIImagePicker to set the image in a UIImageView - swift

Question

This is how my code currently looks like. What I expect to happen is the profileImage (UIImageView) to display the selected image as currently it is not happening.
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
#IBOutlet var profileImage: UIImageView!
let picker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
picker.delegate = self
picker.sourceType = .photoLibrary
}
#IBAction func photoUploadPressed(_ sender: Any) {
if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
let myPickerController = UIImagePickerController()
myPickerController.delegate = self;
myPickerController.sourceType = .photoLibrary
self.present(myPickerController, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage{
selectedImage = image
profileImage.image = image
}
dismiss(animated: true, completion: nil)
}
}
Currently the Image Picker comes up, but once selected it does not change the UIImageView's image.
Any help will be much appreciated.

Answer 1

It is working as expected only error in your code is that you have } missing in photoUploadPressed(_ sender: Any) and you have not declared selectedImage & using it inside imagePickerController
Working code
import UIKit
class ViewController: UIViewController , UIImagePickerControllerDelegate, UINavigationControllerDelegate{
let picker = UIImagePickerController()
var selectedImage: UIImage?
#IBOutlet weak var profileImage: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
picker.delegate = self
picker.sourceType = .photoLibrary
}
#IBAction func potoUploadPressed(_ sender: Any) {
if UIImagePickerController.isSourceTypeAvailable(.photoLibrary){
let myPickerController = UIImagePickerController()
myPickerController.delegate = self;
myPickerController.sourceType = .photoLibrary
self.present(myPickerController, animated: true, completion: nil)
}// It is missing in your code
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage{
selectedImage = image // You have not declared selectedImage
profileImage.image = image
}
dismiss(animated: true, completion: nil)
}
}
