How to push SDWebImage images to a detail view - ios

Question

I'm trying to figure out a way to push images that are loaded via SDWebImage on a TableView, to a view (DetailView) where the image can be viewed in fullscreen.
I have the images loaded from URLs displaying on a table view correctly. But when I tap on one, it segues to another view (DetailView) that is blank when I have a UIImage there. For some reason, the image is not loading.
Thanks!
Here is the TableView code:
import UIKit
class TableViewController: UITableViewController {
var imageURLs = [String]()
override func viewDidLoad() {
super.viewDidLoad()
imageURLs = ["https://i.imgur.com/lssFB4s.jpg","https://i.imgur.com/bSfVe7l.jpg","https://i.imgur.com/vRhhNFj.jpg"]
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func prepare(for segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "DetailView") {
let VC = segue.destinationViewController as! DetailViewController
if let indexpath = self.tableView.indexPathForSelectedRow {
let Imageview = imageURLs[indexpath.row] as String
VC.SentData1 = Imageview
}
}
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell")
let cell2: TableViewCell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! TableViewCell
let imagename = UIImage(named: imageURLs[indexPath.row])
cell2.cellImage.image = imagename
let imageView = cell?.viewWithTag(1) as! UIImageView
imageView.sd_setImage(with: URL(string: imageURLs[indexPath.row]))
return cell!
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return imageURLs.count
}
Here is the DetailView code:
import UIKit
class DetailViewController: UIViewController {
#IBOutlet weak var Detailimageview: UIImageView!
var SentData1:String!
override func viewDidLoad() {
super.viewDidLoad()
Detailimageview.image = UIImage(named: SentData1)
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/

Answer 1

You are using UIImage(named:) in your destination VC. This will try and load the image from your bundle, not from the network. You should use sd_setImage to fetch it from the network (or via cache if it has already been fetched):
Detailimageview.sd_setImage(with: URL(string:self.SentData1))
Note that properties and variables should start with a lower case letter by convention

Answer 2

When you load your detail view, you are passing the web URL for the image you want to load but then trying to load it from the bundle with UIImage(named: SentData1).
Instead you should just be loading it the same way you are doing it in your tableview cells by doing something like Detailimageview.sd_setImage(with: URL(string: SentData1))
