Perform Segue from UICollectionViewCell Button different from Cell Click

Question

I have a UICollectionViewCell, with a UIButton. And I have two different actions. The first one, when the user presses the cell, it will segue to anoth

Answer 1

Here's an elegant solution that only requires a few lines of code:

1. Create a custom UICollectionViewCell subclass
2. Using storyboards, define an IBAction for the "Touch Up Inside" event of your button
3. Define a closure
4. Call the closure from the IBAction

Swift 4+ code

class MyCustomCell: UICollectionViewCell {

        static let reuseIdentifier = "MyCustomCell"

        @IBAction func onAddToCartPressed(_ sender: Any) {
            addButtonTapAction?()
        }

        var addButtonTapAction : (()->())?
    }

Next, implement the logic you want to execute inside the closure in your

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: MyCustomCell.reuseIdentifier, for: indexPath) as? MyCustomCell else {
            fatalError("Unexpected Index Path")
        }

        // Configure the cell
        // ...


        cell.addButtonTapAction = {
            // implement your logic here, e.g. call preformSegue()  
            self.performSegue(withIdentifier: "your segue", sender: self)              
        }

        return cell
    }

You can use this approach also with table view controllers.
