Question

这里我试图删除特定的索引数据，当从使用模型类保存的数组中按下删除按钮时，任何人都可以帮助我从数组中删除数据而不显示在集合视图中吗？

我在这里试过这段代码

我在这里声明为数组

var cartItemsModel = [CartItems]()

以下是我的删除按钮操作

 @objc func deleteAction(sender : UIButton){
        let buttonPosition = sender.convert(CGPoint(), to: cartCollectionView)
        let indexPath = cartCollectionView.indexPathForItem(at: buttonPosition)
        self.deleteIndexPath = indexPath
        self.Index = sender.tag
        let obj = cartItemsModel[(indexPath?.row)!]
        self.cartItemsModel.remove(at: (indexPath?.row)!)
        self.itemId = obj.itemID
        self.price = obj.price
        //        view.isUserInteractionEnabled = false
        let attribute = RappleActivityIndicatorView.attribute(style: .apple, tintColor: .white, screenBG: .darkGray, progressBG: .black, progressBarBG: .orange, progreeBarFill: .red, thickness: 4)
        RappleActivityIndicatorView.startAnimatingWithLabel("Processing...", attributes: attribute)
        //        UIApplication.shared.beginIgnoringInteractionEvents()
        if loginCheck == 1 {
            let customerDeleteAPI = "\(domainName)/V1/carts/mine/items/\(itemId!)/"
            customerItemsDeleteDownloadJsonWithURL(customerItemsAPI: customerDeleteAPI)
        }else {
            let deleteApi = "\(domainName)/en/V1/guest-carts/\(self.guestQuoteId!)/items/\(itemId!)/"
            deleteItemsDownloadJsonWithURL(deleteItemsAPI: deleteApi)
        }
    }

下面根据响应调用delete api之后我试图删除所选的数组并且代码是

self.cartItemsModel.remove(at: (self.deleteIndexPath?.row)!)

我尝试了另一个代码，如下所示

self.cartItemsModel.remove(at: self.Index!)

请检查以下标记的答案。它会解决你的问题。

delete item from collection view

但是，在您成功的API调用使用这些方法之后。

此外，请先在code D

之前删除数组中的项目

如何在swift 3中删除数组中的模型类数据？
