So, on my Storyboard I have an UIViewController with a Container View which it has an UITableViewController as embed. That's how it looks like: https://i.imgur.com/0yBWtbG.png

But now I want to set a picture taken by the camera, but the problem is: The UIImageView is inside the UITableViewController and the button for opening the camera is inside the UIViewController (you can see the camera icon on the screenshot I uploaded).

So, I tried this:

Code for the UIViewController:

@IBAction func openCamera(_ sender: UIButton) {

    let image = UIImagePickerController()

    image.delegate = self



    image.sourceType = UIImagePickerController.SourceType.camera

    image.allowsEditing = false



    self.present(image, animated: true)

    {



    }

}

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

{



    let info = convertFromUIImagePickerControllerInfoKeyDictionary(info)



    if let image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.originalImage)] as? UIImage

    {

        takenPhoto = image //takenPhoto is a global variable

        let CIV = CreateIssue()

        CIV.showImage()

    }

    else

    {



    }



    self.dismiss(animated: true, completion: nil)

}

fileprivate func convertFromUIImagePickerControllerInfoKeyDictionary(_ input: [UIImagePickerController.InfoKey: Any]) -> [String: Any] {

    return Dictionary(uniqueKeysWithValues: input.map {key, value in (key.rawValue, value)})

}





fileprivate func convertFromUIImagePickerControllerInfoKey(_ input: UIImagePickerController.InfoKey) -> String {

    return input.rawValue

}

}

Code for the UITableViewController:

public func showPicture() {

  ivPicture.isHidden = false //here I get Unexpectedly found nil after taking a picture from the camera

  ivPicture.image = takenPhoto

}

However, if I try to call the function in the ViewDidLoad, it works fine:

override func viewDidLoad() {

  showPicture()

}

The last few days, I posted a similar issue but I was trying to change a variable from another swift file through segues, and I was told to use the prepare for segue method but in this case I am just calling a function of another swift file and the obejcts belong to the same swift file. Would I need to use the prepare for segue method, too? Or what am I doing wrong?

Thank you in advance

You create an instance of the child vc

let CIV = CreateIssue()

CIV.showImage()

that not loaded from storyboard so all outlets are nil , so replace this

let CIV = CreateIssue()

with

let CIV =  self.children[0] as! CreateIssue

One thing to keep in mind - A UIView, Tabbleview, and it's cells are all different classes / objects. They don't have any natural relation between one another even though they appear on the same user interface. A button in a tableview cell is a member of that Cell's class rather than the Table or the View which contains that Table.

One question - do you need to have this button in a Tableview cell or can it simply exist as part of your UIView? It's unclear from your example if you need to repeat these cells / have multiple instances of them (the typically UITableViewCell use case) or if a single cell is all you are looking for.
