So I built an app which loads the news into the tableView cells.
Now I want the user to be able to open individual article.
To do that I passed the selected cells using prepareForSegue method and it works but partially.
It passes the title and image properly but the full text is shown partially, to be precise it is shown as in the cells.
Here is my table of news class:
import Alamofire //Framework for handling http requests
import UIKit
import AlamofireImage
class NewsTableViewController: UITableViewController {
//Custom struct for the data
struct News {
let title : String
let text : String
let link : String
let imgUrl : String
init(dictionary: [String:String]) {
self.title = dictionary["title"] ?? ""
self.text = dictionary["text"] ?? ""
self.link = dictionary["link"] ?? ""
self.imgUrl = dictionary["imgUri"] ?? ""
}
}
//Array which holds the news
var newsData = [News]()
// Download the news
func downloadData() {
Alamofire.request("https://api.sis.kemoke.net/news").responseJSON { response in
print(response.request as Any) // original URL request
print(response.response as Any) // HTTP URL response
print(response.data as Any) // server data
print(response.result) // result of response serialization
//Optional binding to handle exceptions
self.newsData.removeAll() // clean the data source array
if let json = response.result.value as? [[String:String]] {
for news in json {
self.newsData.append(News(dictionary: news))
}
self.tableView.reloadData()
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
downloadData()
tableView.rowHeight = 100
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return newsData.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as? newsCellTableViewCell
let news = newsData[indexPath.row]
cell?.headline.text = news.title
Alamofire.request(news.imgUrl).responseImage { response in
debugPrint(response)
print(response.request as Any)
print(response.response as Any)
debugPrint(response.result)
let cellImage = response.result.value
if let image = response.result.value {
print("image downloaded: \(image)")
}
cell?.thumbnailImage.image = cellImage
}
print(news.imgUrl)
return cell!
}
// MARK: - Navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showArticle" {
let nextScene = segue.destination as! ArticleViewController
// Pass the selected object to the new view controller.
if let indexPath = self.tableView.indexPathForSelectedRow {
let selectedCells = newsData[indexPath.row]
nextScene.articleTitleString = selectedCells.title
nextScene.receiveFullText = selectedCells.title
//Downloading an image to be displayed in a single article
Alamofire.request(selectedCells.imgUrl).responseImage { response in
debugPrint(response)
print(response.request as Any)
print(response.response as Any)
debugPrint(response.result)
let cellImage = response.result.value
nextScene.articleImage.image = cellImage!
}
}
}
}
}
And here is my destination view controller for the single article in which I am passing the information
class ArticleViewController: UIViewController {
#IBOutlet weak var articleTitle: UILabel!
var articleTitleString = ""
#IBOutlet weak var articleImage: UIImageView!
#IBOutlet weak var fullText: UITextView!
var receiveFullText = ""
override func viewWillAppear(_ animated: Bool) {
articleTitle.text = articleTitleString
fullText.text = receiveFullText
}
}
And this is what happens

See? The full text is not shown even though the server is returning full text.
I did test this by creating a textView in another view controller and get the text from the server and it worked fine.
The issue looks like it's copying a layout of the label in the cell and displaying what is in that label.
Also a tried putting another label in to the cell to load the text init and it worked properly, than after tapping a cell it displayed what was in that label.
What I want is to load a full text when this segue happens.
nextScene.articleTitleString = selectedCells.title
nextScene.receiveFullText = selectedCells.title
You are passing the title twice instead of the full text...

In firebase, I have a storage with PDF's and a collection that has a reference to the stored PDF, along with the name of the PDF.
I'm retrieving the collection documents and display the headline in a tableview.
I want to be able to click the tableview cell, then display the pdf in a webkit view in another viewcontroller.
How do I fetch the PDF in storage and display it in webkit view?
My code so far:
Handler
class PDFHandler {
static let db = Firestore.firestore()
static let storage = Storage.storage()
static var list = [PDF]()
static var downloadURL : String?
static func Create(title: String, url: String){
}
static func startListener(tableView: UITableView){
print("Listening has begun")
db.collection("PDF").addSnapshotListener { (snap, error) in
if error == nil{
self.list.removeAll()
for pdf in snap!.documents{
let map = pdf.data()
let head = map["Headline"] as! String
let url = map["URL"] as? String ?? "empty"
let newPDF = PDF(id: pdf.documentID, headline: head, url: url)
print(newPDF)
self.list.append(newPDF)
}
DispatchQueue.main.async {
tableView.reloadData()
}
}
}
}
static func downloadPdfs(pdfID: String, pdfurl: String){
print("Download initiated")
let pdfRef = storage.reference(withPath: pdfID)
pdfRef.getData(maxSize: 99999999999) { (data, error) in
if error == nil{
print("Success downloading PDF")
DispatchQueue.main.async {
}
}else{
print("Error fetching pdf")
}
}
}
static func getSize() -> Int{
return list.count
}
static func getPDFat(index: Int) -> PDF{
return list[index]
}
}
Tableview
class ReportViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

return cell!
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? PDFViewController{

I just began to learn Firebase a week ago, but right now I am facing a problem of not able to load image from Firebase to my TableViewCell. I can retrieve data such as text information and the URL of the image from Firebase Realtime Database but not able to make use of those URL in order to fire up image on the TableViewCell. May you all help me identify the problems? I can retrieve everything such as text information as well as the image URL but how can I make the image pop up on the cell? All your help would be highly appreciate!
This is the ViewController that responsible to display the TableViewCell

return
}

}
}.resume()
}
return cell
}
let ref = Database.database().reference()
// Array of PlasticItem
var arrItem = [RetrieveData]()
#IBOutlet weak var tblView: UITableView!

retRef.observe(DataEventType.value) { (dataSnapshot) in
// Remove array item everytime there is a new reference to the data in Firebase
self.arrItem.removeAll()

I'm trying to learn iOS programming so I thought it would be a good idea to emulate instagrams feed. Everyone uses this basic feed and I would like to know how to do it.
The basic idea is to have one image/text post show up in a single column. Right now I have a a single image to be shown.
I'm currently extracting the image url correctly from firebase. The only issue is that my CollectionView still is showing up empty. I started this project months ago and I forget where the tutorial is at. Please help me fill in the blanks. Here is the code:
import UIKit
import SwiftUI
import Firebase
import FirebaseUI
import SwiftKeychainWrapper
class FeedViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource{
#IBOutlet weak var collectionview: UICollectionView!
//var posts = [Post]()
var posts = [String](){
didSet{
collectionview.reloadData()
}
}
var following = [String]()
var posts1 = [String]()
var userStorage: StorageReference!
var ref : DatabaseReference!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
posts1 = fetchPosts()
//let myIndexPath = IndexPath(row: 0, section: 0)
//collectionView(collectionview, cellForItemAt: myIndexPath)
//print(self.posts1.count)
}
func fetchPosts() -> [String]{
let uid = Auth.auth().currentUser!.uid
let ref = Database.database().reference().child("posts")
let uids = Database.database().reference().child("users")
uids.observe(DataEventType.value, with: { (snapshot) in
let dict = snapshot.value as! [String:NSDictionary]
for (_,value) in dict {
if let uid = value["uid"] as? String{
self.following.append(uid)
}
}
ref.observe(DataEventType.value, with: { (snapshot2) in
let dict2 = snapshot2.value as! [String:NSDictionary]
for(key, value) in dict{
for uid2 in self.following{
if (uid2 == key){
for (key2,value2) in value as! [String:String]{
//print(key2 + "this is key2")
if(key2 == "urlToImage"){
let urlimage = value2
//print(urlimage)
self.posts1.append(urlimage)
self.collectionview.reloadData()
print(self.posts1.count)
}
}
}
}
}
})
})
//ref.removeAllObservers()
//uids.removeAllObservers()
print("before return")
print(self.posts1.count)
return self.posts1
override func viewDidLayoutSubviews() {
collectionview.reloadData()
}
func numberOfSections(in collectionView: UICollectionView) ->Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return posts1.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "PostCell", for: indexPath) as! PostCell
cell.postImage.sd_setImage(with: URL(string: posts1[indexPath.row]))
//creating the cell
//cell.postImage.downloadImage(from: self.posts[indexPath.row])
// let storageRef = Storage.storage().reference(forURL: self.posts[indexPath.row].pathToImage)
//
//
print("im trying")
//let stickitinme = URL(fileURLWithPath: posts1[0])
//cell.postImage.sd_setImage(with: stickitinme)
//cell.authorLabel.text = self.posts[indexPath.row].author
//cell.likeLabel.text = "\(self.posts[indexPath.row].likes) Likes"
return cell
}
#IBAction func signOutPressed(_sender: Any){
signOut()
self.performSegue(withIdentifier: "toSignIn", sender: nil)
}
#objc func signOut(){
KeychainWrapper.standard.removeObject(forKey:"uid")
do{
try Auth.auth().signOut()
} catch let signOutError as NSError{
print("Error signing out: %#", signOutError)
}
dismiss(animated: true, completion: nil)
}
/*

*/
}
UPDATE
The observe call is not updating the value of posts (the dictionary). Once the observe call exits, the value of posts is set back to empty.
PostCell class as asked:
import UIKit
class PostCell: UICollectionViewCell {
#IBOutlet weak var postImage: UIImageView!
#IBOutlet weak var authorLabel: UILabel!
#IBOutlet weak var likeLabel:UILabel!
#IBOutlet weak var likeBtn:UIButton!
#IBOutlet weak var unlikeBtn:UIButton!
#IBAction func likePressed (_ sender: Any){
}
#IBAction func unlikePressed(_sender: Any){
}
}
I think the problem is:
Your collectionView dataSource is called only once. Since the image url loading is asynchronous, you will need to refresh your collectionview every time new data is appended to your datasource array like this:
self.posts.append(urlimage)
collectionView.reloadData()
or:
var posts = [UIImage](){
didSet{
collectionView.reloadData()
}
}
Hope this helps.
Edit update:
Regarding the asynchronous calls, i think you should use escaping closure that runs the code block once the network request receives a response.
First separate the network call functions like:
func fetchUsers(completion: #escaping(_ dictionary: [String: NSDictionary])->()){
let uid = Auth.auth().currentUser!.uid
let uids = Database.database().reference().child("users")
uids.observe(DataEventType.value, with: { (snapshot) in
let dict = snapshot.value as! [String:NSDictionary]
completion(dict)
})
}
func fetchURLS(completion: #escaping(_ dictionary: [String: String])->()){
let ref = Database.database().reference().child("posts")
ref.observe(DataEventType.value, with: { (snapshot2) in
let dict2 = snapshot2.value as! [String:String]
completionTwo(dict2)
})
}
Then, the parsing functions:
func parseUsers(dictionary: [String: NSDictionary]){
for (_,value) in dictionary {
if let uid = value["uid"] as? String{
self.following.append(uid)
}
}
fetchURLS { (urlDictionary) in
self.parseImageURLS(dictionary: urlDictionary)
}
}
func parseImageURLS(dictionary: [String: String]){
for(key, value) in dictionary{
for uid2 in self.following{
if (uid2 == key){
for (key2,value2) in value as! [String:String]{
//print(key2 + "this is key2")
if(key2 == "urlToImage"){
let urlimage = value2
//print(urlimage)
self.posts1.append(urlimage)
self.collectionview.reloadData()
print(self.posts1.count)
}
}
}
}
}
}
Then you add:
fetchUsers { (usersDictionary) in
self.parseUsers(dictionary: usersDictionary)
}
in viewDidLoad()
Hope this solves your problem. On a side note: I recommend using models and separating the network calls in a different file. Feel free to ask any questions.
I figured out how to do it after more searching.
I was incorrectly assuming that the CollectionView is loaded after the viewDidLoad() function is done. The helper classes for a CollectionView are called to a call of reloadData.
I observed that my reloadData call wasn't being called. In order to make this work, I add 2 lines of code to the viewDidLoad function:
collectionview.delegate = self
collectionview.dataSource = self
With this change, the images now load.
I've already searched through some of the answers that have been asked about this but none of them seem to apply/work in my situation which is why I've decided to ask the community. I am simply trying to pass the data from the table view cell to the next view controller. I have gotten as far as being able to display the information in my cells accurately however whenever i select the row it just shows the view controller with no information
I have tried to set the labels and pictures to whatever the UITableViewCell may show but it is not working. I created an NSObject class that defines the variables which is why it is confusing me as to how to pass the data through to the next view Controller.
This is my AddFriendViewController where I fetch the users from Firebase and it displays my information on the tableview
class AddFriendViewController: UIViewController {
var users = [Users]()
var databaseRef = Database.database().reference()
#IBOutlet weak var friendsTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
friendsTableView.delegate = self
friendsTableView.dataSource = self
fetchUser()
}
func fetchUser() {
databaseRef.child("users").observe(.childAdded) { (snapshot) in
if let dictionary = snapshot.value as? [String: AnyObject] {
let user = Users()
user.nameOfUser = dictionary["nameOfUser"] as? String ?? ""
user.email = dictionary["email"] as? String ?? ""
user.profileImageURL = dictionary["profileImageURL"] as? String ?? ""
self.users.append(user)
DispatchQueue.main.async {
self.friendsTableView.reloadData()
}
}
}
}
}
extension AddFriendViewController: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.users.count
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let friendCell = UITableViewCell(style: .subtitle, reuseIdentifier: "friendCell")
let user = users[indexPath.row]
friendCell.textLabel?.text = user.nameOfUser
friendCell.detailTextLabel?.text = user.email
if let profileImageURL = user.profileImageURL {
let url = URL(string: profileImageURL)
URLSession.shared.dataTask(with: url!) { (data, response, error) in
if error != nil {
print(error)
return
}
DispatchQueue.main.async {
friendCell.imageView?.image = UIImage(data: data!)
}
}.resume()
}
return friendCell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "showFriendProfile", sender: self.users[indexPath.row])
self.friendsTableView.deselectRow(at: indexPath as IndexPath, animated: true)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showFriendProfile" {
if let indexPath = friendsTableView.indexPathForSelectedRow {
let dvc = segue.destination as! DetailViewController
***This is where I am confused as to what I should be doing***
//EDIT1:
print("The nameOfUser is \(user.nameOfUser!)")
print("The email is \(user.email!)")
}
}
}
}
This is my Users Class:
class Users: NSDictionary {
var nameOfUser: String?
var email: String?
var profileImageURL: String?
}
This is my DetailViewController:
class DetailViewController: UIViewController {
var nameOfUser = String()
var email = String()
var profileImageURL = UIImage()
var ref: DatabaseReference?
#IBOutlet weak var profileImageView: UIImageView!
#IBOutlet weak var nameOfUserLabel: UILabel!
#IBOutlet weak var emailLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
nameOfUser = nameOfUserLabel.text!
email = emailLabel.text!
profileImageURL = profileImageView.image!
}
}
The obvious goal is to simply click on the cell to show the data on the next view controller. I understand similar questions have been asked in the past but I truly don't know how to use those as the solution to my problem. Any help will be greatly appreciated and please let me know if there is anything I need to clarify.
EDIT1:
I added the print statement on the prepare for segue function and noticed it is at least pulling the information but for some reason not passing it to the next view controller.
Thank you
You just need to get your sender and set the properties of the detail view controller.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showFriendProfile" {
guard let dvc = segue.destination as? DetailViewController else {
return
}
if let user = sender as? Users {
DispatchQueue.main.async {
dvc.nameOfUserLabel.text = user.nameOfUser
dvc.emailLabel.text = user.email
let url = URL(string: user.profileImageURL!)
let data = try? Data(contentsOf: url!)
dvc.profileImageView.image = UIImage(data: data!)
}
}
}
}
1- Send the object ( Make sure to connect the segue source to the vc itself not to the cell )
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showFriendProfile" {
if let indexPath = friendsTableView.indexPathForSelectedRow {
let dvc = segue.destination as! DetailViewController
dvc.user = sender as! Users
}
}
}
class DetailViewController: UIViewController {
var user:Users! // add this then inside viewDidLoad set the labels
}
2- Don't ise URLSession.shared.dataTask(with: url!) { (data, response, error) inside cellForRowAt consider using SDWebImage
import SDWebImage // install pods then add this line top of the vc
friendCell.imageView?.sd_setImage(with: URL(string:urlStr), placeholderImage: UIImage(named: "placeholder.png"))
3- No need for DispatchQueue.main.async { inside
DispatchQueue.main.async {
self.friendsTableView.reloadData()
}
As firebase callbacks run in main thread by default
I'm creating an e-commerce app with (Moltin.com) SDK, I set every thing well as it shown in the documentation but now I need to load multi images of single product in table view with custom cell, I set the shown code below and all I can get is a single image my app ignore load the other images view controller code is
class vc: UIViewController , UITableViewDelegate, UITableViewDataSource {
var productDict:NSDictionary?
#IBOutlet weak var tableview: UITableView!
fileprivate let MY_CELL_REUSE_IDENTIFIER = "MyCell"
fileprivate var productImages:NSArray?
override func viewDidLoad() {
super.viewDidLoad()
tableview.delegate = self
tableview.dataSource = self
Moltin.sharedInstance().product.listing(withParameters: productDict!.value(forKeyPath: "url.https") as! [String : Any]!, success: { (response) -> Void in
self.productImages = response?["result"] as? NSArray
self.tableview?.reloadData()
}) { (response, error) -> Void in
print("Something went wrong...")
}
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if productImages != nil {
return productImages!.count
}
return 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: MY_CELL_REUSE_IDENTIFIER, for: indexPath) as! MyCell
let row = (indexPath as NSIndexPath).row
let collectionDictionary = productImages?.object(at: row) as! NSDictionary
cell.setCollectionDictionary(collectionDictionary)
return cell
}
and my custom cell code is
class MyCell: UITableViewCell {
#IBOutlet weak var myImage: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
func setCollectionDictionary(_ dict: NSDictionary) {
// Set up the cell based on the values of the dictionary that we've been passed
// Extract image URL and set that too...
var imageUrl = ""
if let images = dict.value(forKey: "images") as? NSArray {
if (images.firstObject != nil) {
imageUrl = (images.firstObject as! NSDictionary).value(forKeyPath: "url.https") as! String
}
}
myImage?.sd_setImage(with: URL(string: imageUrl))
}
Can anyone show me where is the issue that doesn't let me get all the images of my product?
I'm using SWIFT 3, with XCode
In the code below you are always getting one URL from images array (firstObject).
if let images = dict.value(forKey: "images") as? NSArray {
if (images.firstObject != nil) {
imageUrl = (images.firstObject as! NSDictionary).value(forKeyPath: "url.https") as! String
}
}
myImage?.sd_setImage(with: URL(string: imageUrl))
If I understand correctly you should get every image in images array by the indexPath.row of your tableView.
For example add new parameter to method like this:
func setCollection(with dict: NSDictionary, and index: Int) {
// Set up the cell based on the values of the dictionary that we've been passed
// Extract image URL and set that too...
var imageUrlString = ""
if let images = dict.value(forKey: "images") as? Array<NSDictionary>, images.count >= index {
guard let lImageUrlString = images[index]["url.https"] else { return }
imageUrlString = lImageUrlString
}
guard let imageURL = URL(string: imageUrl) else { return }
myImage?.sd_setImage(with: imageURL)
}
Than when call this method in cellForRow just add indexPath.row to the second param.
But if you want show multiple images in one cell you should add more imageViews to the custom cell or use UICollectionView.
Just ping me if I don't understand you clear.
