                       if let Media_list = jsonData["events"] as? [Any] {

                        self.Mediainfo.removeAll()


                        for i in 0 ..< Media_list.count {

                            if let MediaEventData = Media_list[i] as? [String: Any] {

                                var eventImages = MediaEventData["eventImages"] as? [[String: Any]]

                                if (eventImages?.count)! > 0 {

                                       let bannerImage = eventImages?[0]["bannerImage"] as? String

                                       print(bannerImage as Any)

                                        self.imageUrl = self.url+"/images/events/" + String(describing: bannerImage!)
                                        self.Mediainfo.append(MediaEvent(
                                        eventId: MediaEventData["eventId"]as?String,
                                        date: MediaEventData["date"]as?String,
                                        eventname: MediaEventData["eventName"]as?String,
                                        bannerImages: self.imageUrl


                                    )
                                )

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


        let cell = tableView.dequeueReusableCell(withIdentifier: "Media", for: indexPath)as! MediaCustomTableViewCell

        let  row = indexPath.row

        let media = Mediainfo[row] as MediaEvent

        cell.DisplayDate.text = media.date

        cell.DisplayName.text = media.eventName

        cell.selectionStyle = .none

        cell.DisplayImage.downloadImageFrom(link:media.bannerImages, contentMode: UIViewContentMode.scaleAspectFit)

        return cell
    }


    override func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
        return CGFloat.leastNormalMagnitude
    }


    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
    {

        let media = Mediainfo[(indexPath.row)] as MediaEvent


        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let tabBarController = storyboard.instantiateViewController(withIdentifier: "IMAGEVID") as! UITabBarController

        if let viewControllers = tabBarController.viewControllers,
            let imageController = viewControllers.first as? ImagesCollectionViewController {
            imageController.RecivedData1 = media.bannerImages
        }

        navigationController?.pushViewController(tabBarController, animated: true)




    }

collection view Code :

    override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! ImageCollectionViewCell

        cell.ImageviewCell.downloadImageFrom(link:nameofImages[indexPath.row], contentMode: UIViewContentMode.scaleAspectFit)


        return cell


    }

pls help me......!

Answer 1

  u can do soemthing like this 

let eventImages = MediaEventData["eventImages"] as? [[String: Any]]

 if (eventImages?.count)! > 0 { for i in 0...eventImages.count{ let bannerImage = eventImages?[i]["bannerImage"] as? String self.imageUrl = self.url+"/images/events/" + String(describing: bannerImage!) self.Mediainfo.append(bannerImage) // or like u did u can append to array self.Mediainfo.append(MediaEvent( eventId: MediaEventData["eventId"]as?String, date: MediaEventData["date"]as?String, eventname: MediaEventData["eventName"]as?String, bannerImages: self.imageUrl ) } } 

In didselect

let media = Mediainfo[(indexPath.row)] as MediaEvent imageController.RecivedData1 = media.bannerImages

Your doing like this Means Your are slecting a particular cell and that index your are passing to NextVC.

if you want to show all images You should pass complete array to nextvc

You should declare a array of same type Mediainfo array in Next VC and do like

  EX: imageController.array = Mediainfo
