    if (indexPath.item % 2 == 0) {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "TOWCell", for: indexPath) as! TOWCell
        return cell
    }else {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "UPCOMINGViewCell", for: indexPath) as! UPCOMINGViewCell
        return cell
    }
}


@IBAction func differentcellsButon(_ sender: Any) {
    /// here I need call cells
}

Answer 1

试试这个：

@IBAction func differentcellsButon(_ sender: Any) {
    self.collectionView.reloadData()
}

Answer 2

请尝试以下代码

//Declare this line on top of your ViewController
 var isFirstCell = true


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

        if isFirstCell {
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "TOWCell", for: indexPath) as! TOWCell
            return cell
        }else {
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "UPCOMINGViewCell", for: indexPath) as! UPCOMINGViewCell
            return cell
        }
    }


    @IBAction func differentcellsButon(_ sender: Any) {
        /// here I need call cells
        self.isFirstCell = false
        self.collectionView.reloadData()

    }
