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

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
