didFinishPickingMediaWithInfo not called

Question

I have a UITableViewCell button to take an image and place it back in the cell. When I call the UIImagePickerController and take the image, it doesn't call the following delegate:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject], sender:AnyObject)

This is my takePhotoFunction in UITableViewController:

@IBAction func takePhoto(sender: AnyObject) {
let imagePickerController = UIImagePickerController()
imagePickerController.delegate = self
imagePickerController.allowsEditing = true

let actionSheet = UIAlertController(title: "Choose image souruce", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)

actionSheet.addAction(UIAlertAction(title: "Take Image", style: UIAlertActionStyle.Default, handler: { (alert:UIAlertAction!) -> Void in
    imagePickerController.sourceType = UIImagePickerControllerSourceType.Camera
    self.presentViewController(imagePickerController, animated: true, completion: nil)
}))

actionSheet.addAction(UIAlertAction(title: "Photo Library", style: UIAlertActionStyle.Default, handler: { (alert:UIAlertAction!) -> Void in
    imagePickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
    self.presentViewController(imagePickerController, animated: true, completion: nil)
}))
actionSheet.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil))
self.presentViewController(actionSheet, animated: true, completion: nil)}

In Swift 3, this delegate method is now called:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])

The differences are:

There is an underline _ before picker
info type at the end is changed from [String : AnyObject] to [String : Any]

I had the same issue and when I made these changes it worked.

1. Dont forget to add UIImagePickerControllerDelegate,UINavigationControllerDelegate
2. In your viewDidLoad() add picker.delegate = self
3. Add the delegate methods

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage 
        userImageView.contentMode = .scaleAspectFit
        userImageView.image = chosenImage
        dismiss(animated:true, completion: nil)
    }

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

Hope it helps :)

For swift 4.2

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
   if let chosenImage = info[.originalImage] as? UIImage{
        //use image
    }
}

With the Swift 5 we have slight update.

Here is single screen example I have created to test this with iOS 12.2

import UIKit


class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBOutlet weak var imageView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    //MARK: Open Photos Galley Button Action method
    @IBAction func openPhotosGallery(_ sender: Any) {

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

    //MARK: ImagePicker Controller Delegate methods
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        self.dismiss(animated: true, completion: nil)
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        let chosenImage = info[UIImagePickerController.InfoKey.originalImage] as! UIImage
        imageView.image = chosenImage
        dismiss(animated:true, completion: nil)
    }
}

Use below method for Swift 4.2:

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]){
}

For Swift 4.2

This method has renamed and now should be called as below. I had the same issue that this delegate method was not calling but after this, my issue resolved.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

}

for SWIFT 4.2

I had a similar issue when delegate methods were not called by program.

The imagePicker.delegate = self should be NOT in viewDidLoad() method but in method which opens gallery. Like this:

func openGallery()
    {
        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self

        imagePicker.sourceType = .photoLibrary

        self.present(imagePicker, animated: true, completion: nil)
   }

In Swift 5 we need to use:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any])  {

Worked for me. As I added a tap gesture recognizer to a UIView, the user taps the UIView but the selected image didn't allocate after picker dismiss and the method I used was yellow lined. This method above solved my problem. Thanks – AdPiscinam Dec 11 '22 at 11:41

You have to use that method in this way as there is no delegate method that u have declared:

func imagePickerController(picker: UIImagePickerController!, didFinishPickingMediaWithInfo info:[NSObject : AnyObject]) {
        println("Calling")       
}

Hi Dheeraj, thanks for your answer. I have implemented the delegate method but after the imagpepickercontroller has completed, this method is not called. – Tal Zion Mar 24 '15 at 21:31
did you use the delegate method that i mentioned because you delegate method is not correct and there is no delegate method as u have declared. – Dheeraj Singh Mar 25 '15 at 04:45

The delegate method is now called func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])

I see your imagePickerController.delegate is correctly set so I would assume that you accidently put the didFinishPickingMediaWithInfo code outside your ViewController class

If your UIImagePickerController() object has allowsEditing property set to true then you should get the image in the delegate method as:

if allowsEditing == true

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

        if let pickedImage = info[.editedImage] as? UIImage {

              //do something with image

        }

           dismiss(animated: true, completion: nil)

    }

if allowsEditing == false

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

            if let pickedImage = info[.originalImage] as? UIImage {

                  //do something with image

            }

               dismiss(animated: true, completion: nil)

        }

Maybe sometimes it is caused by ARC? I declare a variable of adapter (present UIImagePickerController for pre-iOS14 below or present PHPickerViewController for iOS 14+) in controller instead in function. It works for me.

var adapter: PHPickerAdapter?

@objc func openGallery(recognizer: UITapGestureRecognizer) {
    adapter = PHPickerAdapter()
    adapter?.delegate = self
    adapter?.showPhotoPicker(.photoLibrary, from: self)
}

In my case the issue was because the picker was declared inside a function so it get deallocated once we exit the function

func showImagePicker() {
    let imagePicker = UIImagePickerController()
    imagePicker.delegate = self
    present(imagePicker, animated: true)
}

The solution was to move the imagePicker object to outside the function body

lazy var imagePicker = UIImagePickerController()
func showImagePicker() {
    imagePicker.delegate = self
    present(imagePicker, animated: true)
}

I made it lazy var since I want to initialize it only when needed.
