Question

i haave problem i can't Pass ImageView From collection to viewcontroller using Firebase Database
This My Code
import UIKit
import Firebase
import FirebaseDatabase
import SDWebImage
import FirebaseStorage
import KRProgressHUD
class ViewControllerCollocation: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource {
#IBOutlet weak var MyColloctaion: UICollectionView!
var imagePicker = UIImagePickerController()
var images = [ImagePost]()
var dbRef:DatabaseReference!
override func viewDidLoad() {
super.viewDidLoad()
setutxent()
designCollectionView()
imagePicker.delegate = self
dbRef = Database.database().reference().child("Images")
/////////
loadDB()
KRProgressHUD.set(style: .custom(background: .black, text: .white, icon: nil))
KRProgressHUD.show(withMessage: "Loading...")
DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
KRProgressHUD.dismiss()
}
}
func loadDB(){
dbRef.observe(DataEventType.value, with: { (snapshot) in
var newImages = [ImagePost]()
for imageFireSnapshot in snapshot.children {
let ImagesFireObject = ImagePost(snapshot: imageFireSnapshot as! DataSnapshot)
newImages.append(ImagesFireObject)
}
self.images = newImages
self.MyColloctaion.reloadData()
}
)}
func collectionView(_ colloction: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return images.count
}
internal func collectionView(_ colloction: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = colloction.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! UploadOneCollectionViewCell
let image = images[indexPath.row]
cell.ImageView.layer.cornerRadius = 13
cell.ImageView.clipsToBounds = true
cell.ImageView.sd_setImage(with: URL(string: image.url), placeholderImage: UIImage(named: "Image1"))
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
}
func designCollectionView() {
let itemSize = UIScreen.main.bounds.width/3 - 3
let layout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 1, left: 1, bottom: 1, right: 1)
layout.itemSize = CGSize(width: itemSize, height: 230)
layout.minimumInteritemSpacing = 1
layout.minimumLineSpacing = 1
//layout.scrollDirection = .horizontal
self.MyColloctaion.isPagingEnabled = true
MyColloctaion.collectionViewLayout = layout
}
func steupbar(){
navigationController?.navigationBar.barTintColor = UIColor.black
tabBarController?.tabBar.barTintColor = UIColor.black
self.navigationController?.navigationBar.titleTextAttributes =
[NSAttributedString.Key.foregroundColor: UIColor.white,
NSAttributedString.Key.font: UIFont(name: "Baskerville-BoldItalic", size: 21)!]
}
#IBAction func Upload(_ sender: Any) {
imagePicker = UIImagePickerController()
imagePicker.allowsEditing = false
imagePicker.sourceType = .photoLibrary
imagePicker.delegate = self
self.present(imagePicker, animated: true, completion: nil)
}
func generateRandom(size: UInt) -> String {
let prefixSize = Int(min(size, 43))
let uuidString = UUID().uuidString.replacingOccurrences(of: "-", with: "")
return String(Data(uuidString.utf8)
.base64EncodedString()
.replacingOccurrences(of: "=", with: "")
.prefix(prefixSize))
}
}
this is My ""ImagePost.swift"""
import Foundation
import FirebaseDatabase
struct ImagePost {
let key: String!
let url:String!
let itemRef:DatabaseReference?
init(url:String, key:String) {
self.key = key
self.url = url
self.itemRef = nil
}
init(snapshot:DataSnapshot) {
key = snapshot.key
itemRef = snapshot.ref
let snapshotValue = snapshot.value as? NSDictionary
if let imageUrl = snapshotValue?["url"] as? String {
url = imageUrl
}else{
url = ""
}
}
}
and This is My detail view
import UIKit
class VC1: UIViewController {
var imageURL : String?
#IBOutlet weak var ImageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
}
}
and Thanks for your help guys!

Answer 1

You can pass image to detail view by getting image in didselect method:
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let image = images[indexPath.row]
let vc = self.storyboard?.instantiateViewController(withIdentifier: "VC1") as! VC1
vc.imageObject = images[indexPath.row]
self.navigationController?.pushViewController(vc, animated: false)
}
Just create a variable as imageObject in VC1 and pass data to it as shown above.
