I have addToCartButton in UICollectionViewCell. What I have to do is to grab the details of the product of the specific cell when the user tapped the button and list it to the another UIViewController. How can It be done in easy and reliable way?

Here is what I have done :

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    let cell = trendingProductCV.dequeueReusableCell(withReuseIdentifier: "TrendingProductsCVCell", for: indexPath) as? TrendingProductsCVCell

    cell?.trendingProductImage.downloadImages(url: trendingProductsDataArray[indexPath.row].images![0].source!)

    cell?.trendingProducttitle.text = trendingProductsDataArray[indexPath.row].title

    cell?.trendingProductSellingPrice.text =  trendingProductsDataArray[indexPath.row].salePrice

    cell?.struckTest(unstruckedText: trendingProductsDataArray[indexPath.row].regularPrice!)

    cell?.trendingAddToCartBtn.addTarget(self, action: #selector(addToCartBtnTapped), for: .touchUpInside)

    return cell!

}



@objc

func addToCartBtnTapped(){



}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {



    let productData = trendingProductsDataArray[indexPath.row]

    let cell = trendingProductCV.dequeueReusableCell(withReuseIdentifier: "TrendingProductsCVCell", for: indexPath) as? TrendingProductsCVCell

    cell?.trendingProductImage.downloadImages(url: productData.images![0].source!)

    cell?.trendingProducttitle.text = productData.title

    cell?.trendingProductSellingPrice.text =  productData.salePrice

    cell?.struckTest(unstruckedText: productData.regularPrice!)

    cell?.trendingAddToCartBtn.addTarget(self, action: #selector(addToCartBtnTapped(sender:)), for:.touchUpInside)



    return cell!

}



@objc func addToCartBtnTapped(sender:UIButton) {



    let buttonPosition:CGPoint = sender.convert(CGPoint.zero, to:self.tblUsers)

    let indexPath = self.tblUsers.indexPathForRow(at: buttonPosition)

    let productData = trendingProductsDataArray[indexPath.row]

}

Try this

you can define protocol on collectionViewCell and fire it when the addToCard button hits on each cell, and in your viewController implement of delegate:

protocol CollectionViewCellDelegate: class {

    func addtoCard(_ cell: TrendingProductsCVCell)

}



class TrendingProductsCVCell: UITableViewCell { 

    weak var delegate: CollectionViewCellDelegate?

    // ... the rest of your code



    @IBAction func addToCardButtonClicked(_ sender: UIButton) { //action of ***addToCard*** 

        delegate?.addToCard(self)

    }

}



class viewController: CollectionViewCellDelegate { //and what you want to implement

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        let cell = trendingProductCV.dequeueReusableCell(withReuseIdentifier: "TrendingProductsCVCell", for: indexPath) as? TrendingProductsCVCell

        cell.delegate = self

        // ... the rest of your code

        return cell

    }



    func addToCard(cell: TrendingProductsCVCell) {

        //do what you want with your cell and its content

    } 

}
