Table View Cell has no Initialiser - ios

I am trying to display table view cell property into different table view cell when button I clicked . I am using story board . I added the Horizontal and vertical stack to contains the image and label properties . I want to display this property into another table view cell when user clicked the show button . In cellFor row function i defined the button action property . I am getting following error .Class 'DetailsViewCell' has no initializers. Cannot use instance member 'mc' within property initializer; property initializers run before 'self' is available
Here is the screenshot of the both view controller .
Here is the code .
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// guard let cell = tableView.dequeueReusableCell(withIdentifier: MovieCell.identifier, for: indexPath) as? MovieCell
// else { return UITableViewCell() }
let cell = tableView.dequeueReusableCell(withIdentifier: MovieViewCell.identifier, for: indexPath) as! MovieViewCell
cell.showButton.tag = indexPath.row
cell.showButton.addTarget(self, action: Selector("movieDetails"), for: .touchUpInside)
let row = indexPath.row
let title = presenter.getTitle(by: row)
let overview = presenter.getOverview(by: row)
let data = presenter.getImageData(by: row)
cell.configureCell(title: title, overview: overview, data: data)
return cell
}
}
Here is the code in identifier class with table view cell.
class MovieViewCell: UITableViewCell {
static let identifier = "MovieViewCell"
#IBOutlet weak var mainStackView: UIStackView!
#IBOutlet weak var movieImage: UIImageView!
#IBOutlet weak var movieTtile: UILabel!
#IBOutlet weak var movieOverview: UILabel!
#IBOutlet weak var showButton: UIButton!
#IBAction func movieDetails(_ sender: UIButton) {
var dc : DetailsViewCell
movieTtile = dc.movieTitle
movieOverview = dc.movieOverview
movieImage = dc.movieImage
}
func configureCell(title: String?, overview: String?, data: Data?) {
movieTtile.text = title
movieOverview.text = overview
if let imageData = data{
movieImage.image = UIImage(data: imageData)
}
}
}
Here is the code for Details view cell.
class DetailsViewCell: UITableViewCell {
#IBOutlet weak var movieTitle: UILabel!
#IBOutlet weak var movieOverview: UILabel!
#IBOutlet weak var movieImage: UIImageView!
var mc : MovieViewCell
movieTitle = mc.movieTtile
movieOverview = mc.movieOverview

Passing data from Table view cell using button delegate

I want to pass the data from one view controller to another view controller when the user clicked the button . I am using button with delegate to pass the table view cell values into different view controller view . In second view controller I have two labels and one image to display the fields but the problem is when I clicked the button it is empty.
Here is the cell code .
import UIKit
protocol CellSubclassDelegate: AnyObject {
func buttonTapped(cell: MovieViewCell)
}
class MovieViewCell: UITableViewCell {
weak var delegate:CellSubclassDelegate?
static let identifier = "MovieViewCell"
#IBOutlet weak var movieImage: UIImageView!
#IBOutlet weak var movieTitle: UILabel!
#IBOutlet weak var movieOverview: UILabel!
#IBOutlet weak var someButton: UIButton!
#IBAction func someButtonTapped(_ sender: UIButton) {
self.delegate?.buttonTapped(cell: self)
}
override func prepareForReuse() {
super.prepareForReuse()
self.delegate = nil
}
func configureCell(title: String?, overview: String?, data: Data?) {
movieTitle.text = title
movieOverview.text = overview
if let imageData = data{
movieImage.image = UIImage(data: imageData)
// movieImage.image = nil
}
}
}
Here is the first view controller code .
import UIKit
class MovieViewController: UIViewController, UISearchBarDelegate {
#IBOutlet weak var userName: UILabel!
#IBOutlet weak var tableView: UITableView!
#IBOutlet weak var searchBar: UISearchBar!
private var presenter: MoviePresenter!
var finalname = ""
var movieTitle = ""
var movieOverview = ""
var movieImage : UIImage?
override func viewDidLoad() {
super.viewDidLoad()
userName.text = "Hello: " + finalname
setUpUI()
presenter = MoviePresenter(view: self)
searchBarText()
}
private func setUpUI() {
tableView.dataSource = self
tableView.delegate = self
}
private func searchBarText() {
searchBar.delegate = self
}
#IBAction func selectSegment(_ sender: UISegmentedControl) {
if sender.selectedSegmentIndex == 0{
setUpUI()
presenter = MoviePresenter(view: self)
presenter.getMovies()
}
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if searchText == ""{
presenter.getMovies()
}
else {
presenter.movies = presenter.movies.filter({ movies in
let originalTitle = movies.originalTitle.lowercased().range(of: searchText.lowercased())
let overview = movies.overview.lowercased().range(of: searchText.lowercased())
let posterPath = movies.posterPath.lowercased().range(of: searchText.lowercased())
return (originalTitle != nil) == true || (overview != nil) == true || (posterPath != nil) == true}
)
}
tableView.reloadData()
}
}
extension MovieViewController: MovieViewProtocol {
func resfreshTableView() {
tableView.reloadData()
}
func displayError(_ message: String) {
let alert = UIAlertController(title: "Error", message: message, preferredStyle: .alert)
let doneButton = UIAlertAction(title: "Done", style: .default, handler: nil)
alert.addAction(doneButton)
present(alert, animated: true, completion: nil)
}
}
extension MovieViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
presenter.rows
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: MovieViewCell.identifier, for: indexPath) as! MovieViewCell
let row = indexPath.row
let title = presenter.getTitle(by: row)
let overview = presenter.getOverview(by: row)
let data = presenter.getImageData(by: row)
cell.delegate = self
cell.configureCell(title: title, overview: overview, data: data)
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let dc = storyboard?.instantiateViewController(withIdentifier: "MovieDeatilsViewController") as! MovieDeatilsViewController
let row = indexPath.row
dc.titlemovie = presenter.getTitle(by: row) ?? ""
dc.overview = presenter.getOverview(by: row) ?? ""
dc.imagemovie = UIImage(data: presenter.getImageData(by: row)!)
self.navigationController?.pushViewController(dc, animated: true)
}
}
extension MovieViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
}
extension MovieViewController : CellSubclassDelegate{
func buttonTapped(cell: MovieViewCell) {
guard (self.tableView.indexPath(for: cell) != nil) else {return}
let customViewController = storyboard?.instantiateViewController(withIdentifier: "MovieDeatilsViewController") as? MovieDeatilsViewController
customViewController?.titlemovie = movieTitle
customViewController?.imagemovie = movieImage
customViewController?.overview = movieOverview
self.navigationController?.pushViewController(customViewController!, animated: true)
}
}
Here is the details view controller code .
class MovieDeatilsViewController: UIViewController {
#IBOutlet weak var movieImage: UIImageView!
#IBOutlet weak var movieTitle: UILabel!
#IBOutlet weak var movieOverview: UILabel!
var titlemovie = ""
var overview = ""
var imagemovie :UIImage?
override func viewDidLoad() {
super.viewDidLoad()
movieTitle.text = titlemovie
movieOverview.text = overview
movieImage.image = imagemovie
}
}
Here is the result when I clicked the button .
The problem is you don't update you're global properties when selecting each of you're row,
If you pass data over cell delegate and pass you're cell through delegate, you can pass data from cell like:
customViewController?.titlemovie = cell.movieTitle.text ?? ""
customViewController?.imagemovie = cell.movieImage.image
customViewController?.overview = cell.movieOverview.text ?? ""
of course it would be better to pass you're data model to you're cell. and then share that through you're delegate not share you're cell, like:
protocol CellSubclassDelegate: AnyObject {
func buttonTapped(cell: MovieModel)
}

Display pictures in a TableView from Firebase Storage in SWIFT without mistake

I have a chat app where people can talk in a group and a little picture is displayed in each cell to show who is talking. I managed to display these pictures from Firebase storage but it is not always the right picture which is displayed at the right place.
It only works when I go to the previous View Controller and coming back the chat View to see the pictures displayed properly in each cell.
I tried override prepareForReuse() but it's not better. Do you have any idea how I could solve this problem ?
import UIKit
class CustomMessageCell: UITableViewCell {
#IBOutlet weak var messageBody: UILabel!
#IBOutlet weak var usernameLabel: UILabel!
#IBOutlet weak var messageBubble : UIView!
#IBOutlet weak var timeLabel: UILabel!
#IBOutlet weak var messageBodyTextView: UITextView!
#IBOutlet weak var userPicture: UIImageView!
#IBOutlet weak var imageButton: UIButton!
override func awakeFromNib() {
super.awakeFromNib()
messageBubble.layer.cornerRadius = messageBubble.frame.size.height / 5
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
override func prepareForReuse() {
super.prepareForReuse()
userPicture.image = nil
messageBodyTextView.text = ""
usernameLabel.text = ""
timeLabel.text = ""
print("prepareforreuse")
}
}
for the class ConversationViewController
class ConversationViewController: UIViewController, UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource, UNUserNotificationCenterDelegate, GADBannerViewDelegate {
// ...
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let message = messageArray[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: "customMessageCell", for: indexPath) as! CustomMessageCell
cell.userPicture.image = nil
cell.selectionStyle = .none
//...
cell.messageBodyTextView.text = messageArray[indexPath.row].messageBody
cell.usernameLabel.text = messageArray[indexPath.row].name
cell.timeLabel.text = dateToShow
cell.userPicture.layer.cornerRadius = cell.userPicture.frame.height / 2
cell.userPicture.clipsToBounds = true
// Charge image
let imagePath = self.storageRef.reference(withPath:"\(message.uid)/resizes/profilImage_150x150.jpg")
imagePath.getData(maxSize: 10 * 1024 * 1024) { (data, error) in
if let error = error {
cell.userPicture.image = UIImage(named: "emptyProfilPic")
print("Got an error fetching data : \(error.localizedDescription)")
// return
}
if let data = data {
cell.userPicture.image = UIImage(data: data)
}
}
return cell
}
}

How to make DetailView change data by indexPath

I'm currently working on a Master-DetailView application and I'm stuck on how to make the data change....
I saw a great tutorial on how to do this :
Tutorial
But the guy is using a blank ViewController & I'm using a TableViewController With static Cells,So it doesn't work.
I want to put the data manually like
var Label1Data = ["You Tapped Cell 1,You Tapped Cell 2,You Tapped Cell 3"]
and it will show in the DetailView by the index path if i pressed the first cell the first data will show up in that Label...i know its not ideal to use static cells here but i do wanna use them design wise.
It will be great if any one could show me finally how can i put the data successfully like i said above and how the Tutorial does it.
MasterViewController Code:
import UIKit
import AVFoundation
class BarsViewController: UITableViewController,UISearchResultsUpdating,UISearchBarDelegate,UISearchDisplayDelegate,UITabBarControllerDelegate{
#IBOutlet var tableViewController: UITableView!
var audioPlayer = AVAudioPlayer()
var sel_val : String?
// TableView Data :
struct User {
var name: String
var streetName: String
var image: UIImage?
}
var allUsers: [User]!
var filteredUsers: [User]!
func createUsers(names: [String], streets: [String], images: [UIImage?]) -> [User] {
var users = [User]()
guard names.count == streets.count && names.count == images.count else { return users }
for (index, name) in names.enumerated() {
let user = User(name: name, streetName: streets[index], image: images[index])
users.append(user)
}
return users
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == self.tableView {
return self.names.count
} else {
return self.filteredUsers.count
}
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
let cell = self.tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
let user:User!
if tableView == self.tableView {
user = allUsers[indexPath.row]
} else {
user = filteredUsers[indexPath.row]
}
cell.photo.image = user.image
cell.name.text = user.name
cell.streetName.text = user.streetName
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
let object = self.storyboard?.instantiateViewController(withIdentifier: "BarProfileTableViewController") as! BarsProfile
let user:User!
if tableView == self.tableView {
user = allUsers[indexPath.row]
} else {
user = filteredUsers[indexPath.row]
}
print("username : \(user.name)")
print("streetName : \(user.streetName)")
MyIndex = indexPath.row
object.barImage = user.image!
object.barName = user.name
object.streetName = user.streetName
self.navigationController?.pushViewController(object, animated: true)
}
DetailView's Code:
import UIKit
import AVFoundation
import MapKit
class BarsProfile: UITableViewController,MKMapViewDelegate {
#IBOutlet var Distance: UILabel!
#IBOutlet var headerImage: UIImageView!
#IBOutlet var OnlineMenu: UIButton!
#IBOutlet var Address: UILabel!
#IBOutlet var ProfileMapView: MKMapView!
#IBOutlet var BarNameLBL: UILabel!
#IBOutlet var streetNameLBL: UILabel!
#IBOutlet var MusicLabel: UILabel!
#IBOutlet var KindOfBarCell: UITableViewCell!
var barName = String()
var barImage = UIImage()
var streetName = String()
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
BarNameLBL.text = barName
streetNameLBL.text = streetName
navigationItem.title = barName
}
How it looks like : ( Red line is a label i would like to put data manually in)
you cant use a TableViewController for your purpose. Instead you can use a normal ViewController with labels and textfields.
In the above picture of yours, you can use a simple label of width = 1 and color = lightGrey so that you can get the same separator line as in the tableview.

Button on tableview cell is not working - swift

I have a button on my custom tableview cell that is showing the users name. When you click on it, you should be taken to his/her profile but nothing happens?
Here is my custom tableview cell class (commentsTableViewCell.swift) :
import UIKit
protocol commentsTableViewCellDelegate {
func namesIsTapped(cell: commentsTableViewCell)
}
class commentsTableViewCell: UITableViewCell {
#IBOutlet weak var nameButton: UIButton!
#IBOutlet weak var commentLabel: UILabel!
#IBOutlet weak var profilePic: UIImageView!
#IBOutlet weak var dateLabel: UILabel!
#IBOutlet weak var uidLabel: UILabel!
var delegate: commentsTableViewCellDelegate?
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
#IBAction func nameIsTapped(sender: AnyObject) {
//4. call delegate method
//check delegate is not nil
if let _ = delegate {
delegate?.namesIsTapped(self)
} else {
print("Delegate is \(delegate)")
}
}
}
Here is the important part of commentsTableViewController.swift:
class commentsTableViewController: UITableViewController, commentsTableViewCellDelegate, UITextViewDelegate {
#IBOutlet weak var commentLabel: UITextView!
#IBOutlet weak var theLabel: UILabel!
var dataGotten = "Nothing"
var updates = [CommentSweet]()
func namesIsTapped(cell: commentsTableViewCell) {
//Get the indexpath of cell where button was tapped
//let indexPath = self.tableView.indexPathForCell(cell)
let allDataSend = cell.nameButton.titleLabel?.text!
self.performSegueWithIdentifier("toDetailtableViewController", sender: allDataSend)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "toDetailtableViewController" {
if let nextVC = segue.destinationViewController as? theProfileTableViewController {
nextVC.viaSegue = sender! as! String
}
}
}
override func viewDidLoad() {
Kindly set the delegate to self.
In cellforRowIndexPath
commentsTableViewCell.delegate = self
Where commentsTableViewCell is the custom UITableViewCell object
I suggest to handle the action of the cell's button in the viewController. You can recognize which button has been tapped by setting a tag for it.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! TableViewCell
cell.myButton?.tag = indexPath.row
cell.myButton?.addTarget(self, action: #selector(), for: .touchUpInside)
return cell
}
func namesIsTapped(tappedButton: UIButton) {
// get the user (from users array for example) by using the tag, for example:
let currentUser = users[tappedButton.tag]
// do whatever you want with this user now...
}

#IBAction func LikeBtn(sender: AnyObject) {
print(sender.tag)
print(IndexPath)
//here i want to know who i can hide the button i have clicked ?
}
Here i want to access the cell in which button is clicked and make changes to UI item inside that cell how can i do that ?
There are many ways to do it. One possible solution is use block.
Add this to ScrollCell
var didLikedTapped: (() -> Void)?
and receive the event of the LikedButton in the cell
#IBAction func LikeBtn(sender: AnyObject) {
didLikedTapped?()
}
Then in cellForRowAtIndexPath of viewController add this
cell.didLikedTapped = {[weak self] in
print(IndexPath)
}
Liked is uibutton in ScrollCell, i don't known, why can you add IBAction for it in ScrollController? . You must implement it in ScrollCell And code:
#IBAction func LikeBtn(sender: UIButton) {
print(sender.tag)
sender.hiden = true
}
And i think, if you have only one UIbutton, it will better. In there, like and unlike is 2 state of uibutton(seleted and none). When you click the button, change it's state
Update:
class sampleCell: UITableViewCell{
#IBOutlet var btnLike : UIButton!
#IBOutlet var btnUnLike : UIButton! // frame of 2 button is equal
override func awakeFromNib() {
super.awakeFromNib()
self.btnUnLike.hidden = true
// ...
}
func updateData(data:AnyObject){ // data's type is Feed
// set data for cell
// i think you should implement in here. and in ScollController call : cell.updateData() , it's better
/* e.x
self.ProductName.text = tan[indexPath.row].ItemName
self.OrginalPrice?.text = "\(tan[indexPath.row].OrginalPrice)"
self.LoveCount.setTitle("\(tan[indexPath.row].LikeCount)"+" Loves", forState: .Normal)
self.Discount.text = "\(tan[indexPath.row].Discount)"+" % off"
*/
}
#IBAction func likeTap(sender:UIButton){ // rememeber set outlet event for btnLike and btnUnLike is this function
if sender == self.btnLike{
self.btnLike.hidden = true
self.btnUnLike.hidden = false
// do s.t
}else if sender == self.btnUnLike{
self.btnLike.hidden = false
self.btnUnLike.hidden = true
// do s.t
}
}
}
Check if the following code help
#IBAction func LikeBtn(sender: AnyObject) {
var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
let indexPath = self.tableView.indexPathForRowAtPoint(position)
let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath!)! as
UITableViewCell
print(indexPath?.row)
}
give the LikeBtn the property indexpath, in cellForRowAtIndexPath method, pass the indexPath to the LikeBtn, then you will know which cell's LikeBtn clicked.
class LikeBtn: UIButton {
var indexPath: NSIndexPath?
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("reuseIdentifier", forIndexPath: indexPath)
// here pass the indexpath to your button
cell.likeBtn.indexPath = indexPath
return cell
}
#IBAction func likeTap(sender: LikeBtn){
if let indexPath = sender.indexPath {
if let cell = tableView.cellForRowAtIndexPath(indexPath) {
//here you will know the exact cell, now you can hide or show your buttons
}
}
}
