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:

  1. There is an underline _ before picker
  2. 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.
