Question

我有两个要匹配的数字数组，然后想要更改TableView中cellForRowAtIndexPath委托中的单元格标签背景。但是，即使条件正确满足，也无法抓住我的条件。这是我的代码：

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if dataLoded {
        if isGroupListView {

            if localGroupChannelsArr.count > 0 {
                noDataFoundView.isHidden = true
            }else {
                noDataFoundView.isHidden = false
            }

            return localGroupChannelsArr.count
        }

        if localSingleChannelsArr.count > 0 {
            noDataFoundView.isHidden = true
        }else {
            noDataFoundView.isHidden = false
        }

        return localSingleChannelsArr.count
    }
}
 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
 var cell = ChatRoomCellView()

    var channelRoom = ChatRoom()
   // var onlineStatus = OnlineUser()

    if isGroupListView {
        channelRoom = localGroupChannelsArr[indexPath.row]
        cell = groupChatRoomsList.dequeueReusableCell(withIdentifier: "GroupRoomCellView") as! ChatRoomCellView
    }else {
        channelRoom = localSingleChannelsArr[indexPath.row]
        cell = singleChatRoomsList.dequeueReusableCell(withIdentifier: "SingleRoomCellView") as! ChatRoomCellView

        for (phone, number) in zip(numbers, onlineUserArray) {

            print(phone)
            print(phone,number.phone!)
                if phone == number.phone
                {
                    if number.status == "online"
                    {
                        print("Matched")
                        cell.onlineStatusLbl.backgroundColor = #colorLiteral(red: 0.08950354904, green: 0.807744801, blue: 0.07534810156, alpha: 1)
                    }
                    else if number.status == "offline"
                    {
                        cell.onlineStatusLbl.backgroundColor = #colorLiteral(red: 0.6666666865, green: 0.6666666865, blue: 0.6666666865, alpha: 1)
                    }
                    else
                    {
                        cell.onlineStatusLbl.backgroundColor = UIColor.clear
                    }
                }
            }
    }

    cell.selectionStyle = .none
    cell.delegate = self
    cell.myIndexPath = indexPath
    cell.chatRoomObj = channelRoom
    cell.onlineUser = onlineUserArray
    cell.configCell()

    return cell
}

现在，当满足条件时，if phone == number.phone 不会更改单元格标签的颜色

Answer 1

我认为问题在于，每次收到单元格请求时，您都在遍历 整个数组 。您可能想做的就是获取number的{{1}}并遍历indexPath.row以查找状态。

这样的事情（我不知道您的确切数据结构，但这应该在正确的位置）：

onlineUserArray

单元格标签在表视图中未捕获值
