Swift 4 TableView单元不显示正确的图像 [英] Swift 4 TableView Cell not Displaying correct images

问题描述

当我滚动tableView时，UIImageView没有显示正确的图像。如何使用 swift 4语言正确完成此操作。

When I scroll the tableView the UIImageView is not displaying the correct image. How can I accomplish this correctly in the swift 4 language.

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


        let cell = tableView.dequeueReusableCell(withIdentifier: "cell")

        //Transform Data From ^ to load at the bottom
        tableView.transform = CGAffineTransform (scaleX: 1,y: -1);
        cell?.contentView.transform = CGAffineTransform (scaleX: 1,y: -1);
        cell?.accessoryView?.transform = CGAffineTransform (scaleX: 1,y: -1);


        let username = cell?.viewWithTag(1) as! UITextView
        username.text = messageArray[indexPath.row].username

        let message = cell?.viewWithTag(2) as! UITextView
        message.text = messageArray[indexPath.row].message

        let timeStamp = cell?.viewWithTag(3) as! UILabel
        timeStamp.text = messageArray[indexPath.row].timeStamp

        let imageView = cell?.viewWithTag(4) as! UIImageView
        let urlString = messageArray[indexPath.row].photoUrl
        imageView.layer.cornerRadius = 10
        imageView.clipsToBounds = true

        //Load profile image(on cell) with URL & Alamofire Library
        let downloadURL = NSURL(string: urlString!)
        imageView.af_setImage(withURL: downloadURL! as URL)

        return cell!
    }

推荐答案

设置 imageView.image = nil 。您正在重用单元格。有时您需要重置单元格组件。

Set imageView.image = nil in the beginning of cellForRowAtIndexPath method. You are reusing cells. Sometimes you need to reset cell components.
