Pass an array in sd_setImage - ios

Question

How can I pass an image array from the first controller (collectionCell) to the second controller (collectionCell) using sg_setImage and class (swift file) using segue?
To load an array of images onto the first controller, I use collectionCell inside tableCell.
ViewController (firstVC):
class ViewController1: UIViewController {
#IBOutlet weak var tableView: UITableView!
var image: [Model] = []
var ref: FIRDatabaseReference!
override func viewDidLoad() {
super.viewDidLoad()
ref = FIRDatabase.database().reference(withPath: "Студии2")
ref.observe(.value, with: { (snapshot) in
var newImages: [Model] = []
for item in snapshot.children {
let object = Model(snapshot: item as! FIRDataSnapshot)
newImages.append(object)
}
self.image = newImages
self.tableView.reloadData()
})
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "segue1" {
if let indexPaths = self.tableView.indexPathForSelectedRow {
let indexPath = indexPaths as NSIndexPath
let dvc = segue.destination as! ViewController2
dvc.photo = [image[indexPath.row]]
}
}
}
}
extension ViewController1: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return image.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell1
cell.images = [image[indexPath.row].image,
image[indexPath.row].image2]
return cell
}
}
tableViewCell (firstVC):
class TableViewCell1: UITableViewCell {
var images = [String]()
#IBOutlet weak var collectionView: UICollectionView!
}
extension TableViewCell1: UICollectionViewDelegate, UICollectionViewDataSource {
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return images.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! CollectionViewCell1
cell.imagesView.sd_setImage(with: URL(string: images[indexPath.item]))
return cell
}
}
collectionViewCell (secondVC):
class ViewController2: UIViewController {
#IBOutlet weak var collectionView: UICollectionView!
var photo: [Model] = []
var ref: FIRDatabaseReference!
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
extension ViewController2: UICollectionViewDelegate, UICollectionViewDataSource {
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return photo.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! CollectionViewCell2
let array = [photo[indexPath.item].image,
photo[indexPath.item].image2]
cell.imagesView.sd_setImage(with: URL(string: array[indexPath.item]!))
// cell.imagesView.sd_setImage(with: URL(string: photo[indexPath.item].image2))
return cell
}
}
class Model (swift file):
class Model {
var image: String!
var image2: String!
var images: [String] = []
var images2: [String] = []
var ref: FIRDatabaseReference!
init(snapshot: FIRDataSnapshot) {
ref = snapshot.ref
let value = snapshot.value as! NSDictionary
let snap1 = value["hall1"] as? NSDictionary
let snap2 = value["hall2"] as? NSDictionary
image = snap1?["qwerty"] as? String ?? ""
image2 = snap2?["qwerty"] as? String ?? ""
if let post1 = snap1 as? [String: AnyObject] {
for (_, value) in post1["images"] as! [String: AnyObject] {
self.images.append(value as! String)
}
}
if let post1 = snap1 as? [String: AnyObject] {
for (_, value) in post1["images"] as! [String: AnyObject] {
self.images2.append(value as! String)
}
}
}
}
