从SDWebimage加载/下载图像并显示在自定义表中查看单元格图像视图

Question

我已经解析了其他值，但是我将如何向imageView显示图像，我已经在Swift中使用了SdWebImage.我想在底部单元格中显示"详细信息" 下面是我的代码

import UIKit
import SystemConfiguration
import MBProgressHUD

public struct Section {
var arrayDataTop: String
var arrayTerms: String
var qrImage:String
var collapsed: Bool
public init( arrayDataTop: String,qrImage: String ,arrayTerms: String, collapsed: Bool = false) {
self.arrayDataTop = arrayDataTop
self.qrImage = qrImage
self.arrayTerms = arrayTerms
self.collapsed = collapsed
}
}
class CollapsibleViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
@IBOutlet weak var tableViewCollapsible:UITableView!
@IBOutlet weak var listImage:UIImageView!
var nodatastr:String = "No Deal Found."
var dealIDCollapsible : String?
var dealDictCollapsible = [String: AnyObject]()
var parentNavigationController: UINavigationController?
private var loadingView:MBProgressHUD?
var sectionDataObj = [Section]()

override func viewDidLoad() {
super.viewDidLoad()
if (!self.isInternetAvailable()){
self.alertMessageShow(title: "No Internet Connection", message: "Make sure your device is connected to the internet.")
}
else{
if self.loadingView == nil {
self.loadingView =  MBProgressHUD.showAdded(to: self.view, animated: true)
}

tableViewCollapsible.estimatedRowHeight = 100.0
tableViewCollapsible.layoutIfNeeded()
tableViewCollapsible.updateConstraintsIfNeeded()
tableViewCollapsible.tableFooterView = UIView()

self.listImageFetch()
dealFetchParticularListing()
}
}




func dealFetchParticularListing(){
let prs = [
"listing_id":dealIDCollapsible,//dealIDCollapsible,
"Deal_fetch_listing": "1" as String
]
Service.CreateDeal(prs as [String : AnyObject]?, onCompletion: { result in
let json = result as? NSDictionary
if let data = json as? [String:Any]{
if let err = data["status"] as? String, err == "success"{
if let data = data["result"] as? [Any]{
//
//fill your data in that local Section obj
//
var sectionDataObj = [Section]()
for sectionObj in data{
if let sectionObjVal = sectionObj as? [String:Any]{
if let qrcode = sectionObjVal["qrcode"] as? String{
if let tnc = sectionObjVal["tnc"] as? String{
if let deal_title = sectionObjVal["deal_title"] as? String{
let sectionValue = Section(arrayDataTop: deal_title, qrImage: qrcode, arrayTerms: tnc)
// access main objects/UIelement on main thread ONLY
sectionDataObj.append(sectionValue)
}
}
}
}
}
DispatchQueue.main.async { () -> Void in
self.sectionDataObj.removeAll()
//
//assign ur data in main sampleData(Section obj) then reload tableView with that data.
//
self.sectionDataObj = sectionDataObj
self.tableViewCollapsible.reloadData()
self.loadingView?.hide(true)
}
}
}
}
})
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

// Header
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "header") as! MyCellData
cell.lblDealTitle.text = sectionDataObj[indexPath.section].arrayDataTop
return cell
}
// Cell
let cell = tableView.dequeueReusableCell(withIdentifier: "detail") as! MyCellData
cell.lblTerm.text = sectionDataObj[indexPath.section].arrayTerms
// here i want to show image 
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension//320.0
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if indexPath.row == 0 {
let collapsed = !sectionDataObj[indexPath.section].collapsed
// Toggle collapse
sectionDataObj[indexPath.section].collapsed = collapsed
self.tableViewCollapsible.reloadSections([indexPath.section], with: .automatic)
}
}
}

class MyCellData:UITableViewCell{
@IBOutlet weak var lblDealTitle: UILabel!
@IBOutlet weak var dealimage: UIImageView!
@IBOutlet weak var lblTerm: UILabel!
@IBOutlet weak var qrCodeImage: UIImageView!
}

请帮我解决这个问题，提前谢谢。所有事情都正常工作，我能够看到其他细节。帮助将不胜感激。请帮助我，我正在为这个问题而苦苦挣扎。

这样更新您的tableView cellForRowAt以显示图像或来自部分的单元格DataObj

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

// Header
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "header") as! MyCellData
cell.lblDealTitle.text = sectionDataObj[indexPath.section].arrayDataTop
return cell
}
// Cell
let cell = tableView.dequeueReusableCell(withIdentifier: "detail") as! MyCellData
cell.lblTerm.text = sectionDataObj[indexPath.section].arrayTerms
let imgUrl = sectionDataObj[indexPath.section]. qrImage
cell.qrCodeImage.sd_setImage(with: URL(string:imgUrl), completed: nil)
return cell
}
