passing image from collectionViewCell which is located tableviewCell

Question

I ask for help with determining the right approach

when I click on the picture I need to pass text and her to new VC, but the problem is that the project has a great depth struct

the cell lies in the collectionView, which is in the tableViewCell

How do I properly implement the transfer? (the number of cells is generated automatically)

Another complication is that the code of the cell with which I work lies in another cell.

those. the transfer of information must also be written in it.

import UIKit
import moa

class RealPhotoInfoTableViewCell: UITableViewCell {

    @IBOutlet private weak var MyCollection: UICollectionView!

    var model: RealPhoto!

    func setCollectionViewDataSourceDelegate(dataSourceDelegate: UICollectionViewDataSource & UICollectionViewDelegate, forRow row: Int) {
        MyCollection.delegate = self
        MyCollection.dataSource = self
        MyCollection.reloadData()
    }
}

extension RealPhotoInfoTableViewCell: UICollectionViewDelegate, UICollectionViewDataSource {
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        print(model?.data.count as Any)
        return model?.data.count ?? 0
    }


    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "RPhotoCell", for: indexPath) as! RealPhotoCollectionViewCell

        cell.realPhotoImage.moa.url = model?.data[indexPath.row].photo

        return cell
    } 
}

Add a var

class RealPhotoInfoTableViewCell: UITableViewCell {
   weak var delegate:VCName?

Inside cellForRowAt of the table do

cell.delegate = self

Now you can do this inside didSelectItemAt of the collection

delegate?.sendData(image)

thanks, I tried to do as you describe But it does not come out. I will update the question, please take a look. – Сева May 30 '19 at 08:02
@Сева `cell.delegate = self` should be inside the tableView `cellForRowAt` not the collection – Shehata Gamal May 30 '19 at 10:11
it still doesn't work. in the first VC where I have a tableview, I have prescribed `realPfotoCell.delegate = self` and have an error `Cannot assign value of type 'DetailViewController' to type 'ImagesViewController?'` – Сева May 30 '19 at 13:03

You have two options: One is Sh_Khan answer using delegation.

Or you can use Notification observers.

This question has been asked before...

You can use delegate protocol in that case. You can implement that protocol. Please find following sample code for that.

protocol ImageSelectionDelegate {
    func imageClicked(imageURL: String)
}

//Class A
class A : ImageSelectionDelegate{
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        //your existing code
        cell.delegate = self
    }
    //Implement that protocol
    func imageClicked(imageURL: String){
        //You will get url for tapped image
    }
}

class RealPhotoInfoTableViewCell{
    weak var delegate : ImageSelectionDelegate? = nil
    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        delegate.imageClicked(model?.data[indexPath.item].photo)
    }
}
