    return 10
}

}

class ReviewAverageRate: UICollectionViewCell {

var detailControllr = DetailController()
override init(frame: CGRect) {
    super.init(frame: frame)

    setupDigitalReviewAverageRate()
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}


let giveReviewBtn: UIButton = {

    let btn = UIButton()
    btn.setTitle("GIVE REVIEW", for: .normal)

    btn.setTitleColor(.white, for: .normal)

    btn.backgroundColor = UIColor.orange
    btn.titleLabel?.font = UIFont.boldSystemFont(ofSize: 10)
    btn.addTarget(self, action: #selector(giveReviewBtnTarget), for: .touchUpInside)

    return btn
}()

func giveReviewBtnTarget() {

    detailControllr.showAppDetailForApp()

}

func setupDigitalReviewAverageRate() {

    addSubview(giveReviewBtn)

    addConstraintsWithFormat("H:|[v0(80)]|", views:  giveReviewBtn)

    addConstraintsWithFormat("V:|[v0(20)]|", views: giveReviewBtn)

}

}

You need to create delegate for your cell, and then open showAppDetailForApp from your DetailController. — GeneCode, Jul 18 '17 at 05:17

Try this :

Solution 1

In ViewController

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

        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reviewAverageRateCellid, for: indexPath) as! ReviewAverageRate
        cell.detailControllr = self
            cell.giveReviewBtn.addTarget(self, action: #selector(self.giveReviewBtnTarget), for: .touchUpInside)
        return cell
}


func giveReviewBtnTarget() {
   // add your code 

}

Solution 2

In cell class

            btn.addTarget(self, action: #selector(self.giveReviewBtnTarget), for: .touchUpInside)

For any one who still struggle with this problem,

Just need to extend:  UICollectionViewDelegateFlowLayout

Example

class YourClassName: UICollectionViewController, UICollectionViewDelegateFlowLayout { 

...

}
