Question

我是iOS编程新手。如果我的问题听起来很天真，请提前抱歉。我在UITableViewCell中有两个自定义单元格。一个显示图像和标签和其他显示横幅。我想在3个单元格中显示带有图像的标签，然后显示横幅并继续。

目前，我可以根据需要显示它，但是当我滚动时，图像和横幅会更改单元格中的位置。

以下是我的代码： -

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

     if VideosTableViewController.flag >= 1 {
        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomTableViewCell

        let  remoteImageUrlString = imageCollection[indexPath.row]
        let imageUrl = NSURL(string:remoteImageUrlString)

        let myBlock: SDWebImageCompletionBlock! = {(image:UIImage!, error: NSError!, cachetype:SDImageCacheType!, imageURL: NSURL!) -> Void in
         }
        //cell.myImageView?.image = nil

        cell.myImageView.sd_setImageWithURL(imageUrl, completed: myBlock)

        //set label
        cell.myImageLabel.text = labelCollection[indexPath.row]
        print(cell.myImageLabel?.text)

        VideosTableViewController.flag = VideosTableViewController.flag - 1

        return cell
          }
     else
     {
        let adCell = tableView.dequeueReusableCellWithIdentifier("adCell", forIndexPath: indexPath) as! VideosBannerAdCustomTableViewCell

        VideosTableViewController.flag = VideosTableViewController.flag + 3

            VideosTableViewController.flag = 3


        adCell.videosBannerView.adUnitID = "banner id" 
        adCell.videosBannerView.rootViewController = self
        let request : DFPRequest = DFPRequest()
       //request.testDevices = [kGADSimulatorID]
        request.testDevices = ["my test device id"] 
        adCell.videosBannerView.loadRequest(request)

       return adCell

     }
    }

尝试使用indexPath来确定应使用哪个单元格。您正试图在第4个，第8个单元格中显示带有横幅的adCell ....因此，通过此操作非常简单：

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

     if indexPath.row % 4 != 0 || indexPath.row == 0 {
        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CustomTableViewCell

        let  remoteImageUrlString = imageCollection[indexPath.row]
        let imageUrl = NSURL(string:remoteImageUrlString)

        let myBlock: SDWebImageCompletionBlock! = {(image:UIImage!, error: NSError!, cachetype:SDImageCacheType!, imageURL: NSURL!) -> Void in
         }
        //cell.myImageView?.image = nil

        cell.myImageView.sd_setImageWithURL(imageUrl, completed: myBlock)

        //set label
        cell.myImageLabel.text = labelCollection[indexPath.row]
        print(cell.myImageLabel?.text)

        VideosTableViewController.flag = VideosTableViewController.flag - 1

        return cell
          }
     else
     {
        let adCell = tableView.dequeueReusableCellWithIdentifier("adCell", forIndexPath: indexPath) as! VideosBannerAdCustomTableViewCell

        VideosTableViewController.flag = VideosTableViewController.flag + 3

            VideosTableViewController.flag = 3


        adCell.videosBannerView.adUnitID = "banner id" 
        adCell.videosBannerView.rootViewController = self
        let request : DFPRequest = DFPRequest()
       //request.testDevices = [kGADSimulatorID]
        request.testDevices = ["my test device id"] 
        adCell.videosBannerView.loadRequest(request)

       return adCell

     }
    }
