这里我在表视图单元格和表视图单元格中动态加载集合视图数据也是在动态json数组计数上创建的,这里在选择第一个表视图单元格中的集合视图中的任何元素之后,需要重新加载集合视图使用第二个表视图单元格中的新数据任何人都可以帮助我如何在第二个表视图单元格swift 3中重新加载集合视图如果不可能,任何人都可以为我提供任何替代布局来实现这个吗?
这是我的行方法
的单元格 if indexPath.section == 0 {
let cell = addToCartTableView.dequeueReusableCell(withIdentifier: "addToCartCollectionCell") as! AddToCartCollectionTableViewCell
cell.configurableProduct = self.detailModel
print(self.detailModel)
cell.collectionView.tag = indexPath.row
self.addToCartTableView.setNeedsLayout()
self.addToCartTableView.layoutIfNeeded()
cell.collectionView.reloadData()
cell.cellLabel.text = detailModel?.extensionAttribute?.productOptions[indexPath.row].label
if detailModel?.extensionAttribute?.productOptions[indexPath.row].label == "Size"{
cell.sizeGuideBtn.isHidden = false
}else{
cell.sizeGuideBtn.isHidden = true
}
cell.getCurrentRow = indexPath.row
return cell
}else {
let cell = addToCartTableView.dequeueReusableCell(withIdentifier: "addToCartQtyCell") as! AddToCartQuantityTableViewCell
self.addToCartTableView.setNeedsLayout()
self.addToCartTableView.layoutIfNeeded()
cell.QtyLabel.text = "Qty"
return cell
}
这是我的表格视图单元格代码

在集合视图的didSelectItemAt中,通过执行
重新加载包含大小的表格单元格let indexpath = IndexPath(item: value, section: 0)
tableview.reloadRows(at: [indexpath], with: .none)
此处值是您想要提升的行的位置
答案 1 :(得分:0)
创建一个新变量“cellObj”,其数据类型与您添加集合视图的自定义单元格相同。
var cellObj:AddToCartCollectionTableViewCell!
在此行之后添加assign cellObj值。
let cell = addToCartTableView.dequeueReusableCell(withIdentifier: "addToCartCollectionCell") as! AddToCartCollectionTableViewCell
cellObj = cell
***完成后,您可以在任何地方重新加载集合视图。
cellObj.collectionView.reloadData()
答案 2 :(得分:0)
DispatchQueue.main.async {
// cell!.tableView.reloadData()
collectionView.reloadItems(at: [indexPath])
cell!.tableView.reloadData()
}
})
