ios - 在 uicollectionViewCell 上按下按钮时如何获取产品代码？

Question

我有这个代码:

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return productsObjectArray.count
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell10", for: indexPath) as! MainViewCollectionViewCell

        let objProduct = productsObjectArray[indexPath.item]

        cell.titleLabel.text = objProduct.name
        let documentsDir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
        let imageFileName = objProduct.code
        let fullImagePath = documentsDir.appendingPathComponent("GET_PHOTO").path + "/" + imageFileName! + ".jpg"
        cell.imageView.image = UIImage(contentsOfFile:   fullImagePath)

        let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(MainViewControler.rightSwiped))
        swipeRight.direction = UISwipeGestureRecognizerDirection.right
        cell.addGestureRecognizer(swipeRight)

        let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(MainViewControler.leftSwiped))
        swipeLeft.direction = UISwipeGestureRecognizerDirection.left
        cell.addGestureRecognizer(swipeLeft)

        cell.favoriteBtn1.tag = indexPath.row
        cell.favoriteBtn1.addTarget(self, action: #selector(didTapButton(_:)), for: .touchUpInside)

        return cell
    }

    @objc func didTapButton(_ sender: UIButton) {
        let objProduct = productsObjectArray[indexPath.item]
        print(objProduct.id) 
        print(objProduct.code) 
    }


   func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        let productObject = productsObjectArray[indexPath.item]
        showSubViewInContainerViewProductCard(view: "ProductDetailView", object: [productObject], productsFilter: 0, marketProductsFilter: 0, menuFilter: 0, preparationFilter: 0, glutenFilter: 0,  backFromProductView: false)
    }

这是我的 Storyboard:

点击按钮favoriteBtn1后，如何在“点击的产品id:......”中显示点击了哪个产品代码？

我该怎么做？

Answer 1

您可以使用标签概念来识别您按下的对象，

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

    let productCode = productsObjectArray[indexPath.item].code
    cell.favoriteBtn1.tag =  indexPath.item
    cell.favoriteBtn1.addTarget(self, action: #selector(didTapButton(_:)), for: .touchUpInside)
}

和你的按钮操作

@objc func didTapButton(_ sender: UIButton) {
    let productCode = productsObjectArray[sender.tag].code
    print("clicked product id: ", productCode)
}
