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...
}

Here my Item Detail View Controller
import UIKit
class ItemDetailViewController: UIViewController {
var items = [item]()
var name : String = ""
var price : String = ""
var imagee : String = ""
#IBOutlet weak var labelname: UILabel!
#IBOutlet weak var image: UIImageView!
#IBOutlet weak var labelprice: UILabel!

#IBAction func addtobag(_ sender: Any) {
let viewController = storyboard?.instantiateViewController(withIdentifier: "BagViewController") as? BagViewController

viewController?.price = self.price
viewController?.items = self.items
navigationController?.pushViewController(viewController!, animated: true)
}
override func viewDidLoad() {
super.viewDidLoad()
labelname.text = name
labelprice.text = price
image.image = UIImage(named: imagee)
}
}
And here my Bag View Controller
import UIKit
class BagViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var totalprice: UILabel!
#IBOutlet weak var tableview: UITableView!
var items = [item]()
var name : String = ""
var price : String = ""
var imagee : String = ""
override func viewDidLoad() {
super.viewDidLoad()
tableview.delegate = self
tableview.dataSource = self
// Do any additional setup after loading the view.
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return name.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath as IndexPath) as! ShoppingTableViewCell
return cell
}
}
and here my Shopping Table View
import UIKit
class ShoppingTableViewCell: UITableViewCell {
#IBOutlet weak var dfs: UIImageView!
#IBOutlet weak var labelname: UILabel!
#IBOutlet weak var labelprice: UILabel!
#IBOutlet weak var stepperlabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
#IBAction func stepper(_ sender: UIStepper) {
stepperlabel.text = String(Int(sender.value))
}
}
I think your logic is kind of bad, you're instantiating a VC in code but you have a segue, I recommend you pass data through the prepare function:
// MARK: - Navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destination.
if let vc = segue.destination as? BagViewController {
vc.name = self.name
vc.imagee = self.imagee
vc.price = self.price
vc.items = self.items
}
// Pass the selected object to the new view controller.
}
And in your addtobag IBAction you just will call the segue, I recommend you to use a String based segue extension String+PerformSegue.swift it lets you easily perform segue in a given ViewController like this:
#IBAction func addtobag(_ sender: Any) {
"nameOfTheSegue".performSegue(on: self)
// If you don't want to use String+PerformSegue.swift uncomment
// the next line and comment the last one.
// self.performSegue(withIdentifier: "nameOfTheSegue", sender: nil)
}
I am trying to instantiate empty Buyer cells (custom cell) in my table view and then have the user populate the buyers' names. When the user presses the delete button for a row/cell, it should delete the corresponding row/cell regardless of whether or not the textfield for that row has been populated or not. Clearly, I am not getting the desired behavior. For example, when I press delete Row0 (whose textfield says "Buyer 0") and the tableview reloads, Buyer 0 is still there, but one of the empty Buyer cells at the end gets deleted instead.
import UIKit
class EntryAlertViewController: UIViewController {
//Fields/Table
#IBOutlet weak var itemField: UITextField!
#IBOutlet weak var priceField: UITextField!
#IBOutlet weak var tableView: UITableView!
//Visual Components
#IBOutlet weak var mainView: UIView!
#IBOutlet weak var titleView: UIView!
#IBOutlet weak var splitItemButton: UIButton!
#IBOutlet weak var cancelButton: UIButton!
#IBOutlet weak var addItemButton: UIButton!
//Commonly Used Objects/Variables
var potentialBuyers: [String] = []
override func viewDidLoad() {
super.viewDidLoad()
potentialBuyers.append("")
tableView.dataSource = self
tableView.register(UINib(nibName: "BuyerCell", bundle: nil), forCellReuseIdentifier: "ReusableCell")
}
override func viewWillAppear(_ animated: Bool) {
}
#IBAction func splitItemPressed(_ sender: UIButton) {
potentialBuyers.append("")
tableView.reloadData()
}
}
Here are the tableview datasource and the delete button delegate.
extension EntryAlertViewController: UITableViewDataSource, DeleteButtonDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return potentialBuyers.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ReusableCell", for: indexPath) as! BuyerCell
cell.deleteButtonDelegate = self
cell.indexPath = indexPath
cell.nameField.text = cell.buyerName
if potentialBuyers.count == 1 {
cell.deleteButton.isHidden = true
} else {
cell.deleteButton.isHidden = false
}
return cell
}
func deletePressed(index: Int) {
potentialBuyers.remove(at: index)
tableView.reloadData()
}
}
And here is my BuyerCell class with the UITextFieldDelegate as an extension.
import UIKit
protocol DeleteButtonDelegate {
func deletePressed(index: Int)
}
class BuyerCell: UITableViewCell {
#IBOutlet weak var deleteButton: UIButton!
#IBOutlet weak var nameField: UITextField!
var deleteButtonDelegate: DeleteButtonDelegate!
var indexPath: IndexPath!
var buyerName: String?
override func awakeFromNib() {
super.awakeFromNib()
self.nameField.delegate = self
}
#IBAction func deletePressed(_ sender: UIButton) {
//print the indexPath.row that this was pressed for
print("delet pressed for \(indexPath.row)")
self.deleteButtonDelegate?.deletePressed(index: indexPath.row)
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
extension BuyerCell: UITextFieldDelegate {
func textFieldDidBeginEditing(_ textField: UITextField) {
print("textFieldDidBeginEditing")
buyerName = nameField.text
}
func textFieldDidEndEditing(_ textField: UITextField) {
print("textFieldDidEndEditing")
buyerName = nameField.text
}
}
Your problem is in this line
cell.nameField.text = cell.buyerName
Cells are reused from a reuse pool, so you can't rely on the cell holding any particular state or value.
Your buyer name needs to come from your data model array.
Something like
cell.nameField.text = self.potentialBuyers[indexPath.row]
Reloading the whole tableview is a bit excessive when you have only deleted a single row; Just delete the relevant row.
You can also clean up your delegation protocol so that there is no need for the cell to track its indexPath -
protocol DeleteButtonDelegate {
func deletePressed(in cell: UITableViewCell)
}
In your cell:
#IBAction func deletePressed(_ sender: UIButton) {
self.deleteButtonDelegate?.deletePressed(in: self)
}
In your view controller:
func deletePressed(in cell: UITableViewCell) {
guard let indexPath = tableView.indexPath(for: cell) else {
return
}
potentialBuyers.remove(at: indexPath.row)
tableView.deleteRows(at:[indexPath], with: .automatic)
}
There is a major issue in your code. You are not updating the data model so the changes in the cells are lost when the user scrolls.
Rather then quite objective-c-ish protocol/delegate in Swift callback closures are much more convenient and efficient. You can use one callback for both updating the model and deleting the cell.
Replace the BuyerCell cell with
class BuyerCell: UITableViewCell {
#IBOutlet weak var deleteButton: UIButton!
#IBOutlet weak var nameField: UITextField!
var callback : ((UITableViewCell, String?) -> Void)?
override func awakeFromNib() {
super.awakeFromNib()
self.nameField.delegate = self
}
#IBAction func deletePressed(_ sender: UIButton) {
callback?(self, nil)
}
}
extension BuyerCell: UITextFieldDelegate {
func textFieldDidBeginEditing(_ textField: UITextField) {
print("textFieldDidBeginEditing")
callback?(self, nameField.text)
}
func textFieldDidEndEditing(_ textField: UITextField) {
print("textFieldDidEndEditing")
callback?(self, nameField.text)
}
}
In the controller in cellForRow assign the callback and handle the actions. The actions work also reliably if cells are reordered, inserted or deleted.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ReusableCell", for: indexPath) as! BuyerCell
let buyerName = potentialBuyers[indexPath.row]
cell.nameField.text = buyerName
cell.callback = { [unowned self] cCell, cName in
let currentIndexPath = tableView.indexPath(for: cCell)!
if let name = cName {
self.potentialBuyers[currentIndexPath.row] = name
} else {
self.potentialBuyers.remove(at: currentIndexPath.row)
tableView.deleteRows(at: [currentIndexPath], with: .fade)
}
}
cell.deleteButton.isHidden = potentialBuyers.count == 1
return cell
}
When i click table view cell click event not working. I am assigned the data to view in custom tableView cell class and passed the value from viewController class. Is there is any problem in assigning data to views in custom table view cell class
ViewController.class
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = self.ViewAllTableView.dequeueReusableCell(withIdentifier: "ViewAllTableViewCell", for: indexPath) as! ViewAllTableViewCell
let products = self.allProducts[indexPath.row]
cell.setData(products: products)
cell.delegate = self
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "allDetail", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? ProductDetailViewController{
let products = self.allProducts[(ViewAllTableView.indexPathForSelectedRow?.row)!]
destination.productID = products.id
}
}
This is Custom Table View Cell class
ViewAllTableViewCell.class
class ViewAllTableViewCell: UITableViewCell {
#IBOutlet weak var ItemImage: UIImageView!
#IBOutlet weak var ItemName: UILabel!
#IBOutlet weak var ItemOfferPrice: UILabel!
#IBOutlet weak var ItemOriginalPrice: UILabel!
#IBOutlet weak var ItemWeight: UILabel!
#IBOutlet weak var ItemCountLabel: UILabel!
var delegate : ViewAllTableViewCellDelegate?
var allProduct: ViewAllProductsData!
func setData(products: ViewAllProductsData){
self.allProduct = products
self.ItemName.text = allProduct.name
self.ItemWeight.text = "\(allProduct.quantity) \(allProduct.unit)"
self.ItemOfferPrice.text = "\(allProduct.price)"
self.ItemOriginalPrice.text = "\(allProduct.originalPrice)"
self.ItemCountLabel.text = "\(allProduct.count)"
let url: URL = NSURL(string: allProduct.image)! as URL
self.ItemImage.af_setImage(withURL: url)
}
#IBAction func ViewAllMinusButton(_ sender: UIButton) {
delegate?.minusCount(data: allProduct)
}
#IBAction func ViewAllPlusbutton(_ sender: UIButton) {
delegate?.addCount(data: allProduct)
}
}
protocol ViewAllTableViewCellDelegate{
func addCount(data: ViewAllProductsData)
func minusCount(data: ViewAllProductsData)
}
It happens because either you haven't conform properly to UITableViewDelegate or you have UITapGestureRecognizer somewhere in your view controller.
It worked for me after changing tableView attribute selection from no selection to single selection
I know it's kinda frequently ask question, but I did some research and none of the solutions work.
so here's my controller with table view
class MainPage: UIViewController, UITableViewDelegate, UITableViewDataSource, YoubikeManagerDelegate {
#IBOutlet weak var tableView: UITableView!
let mainPageCell = MainPageCell()
let mapPage = MapViewController()
var stations: [Station] = []
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
override func viewDidAppear(_ animated: Bool) {
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "infoCell") as! MainPageCell
cell.stationNameLabel.text = stations[indexPath.row].name
cell.stationLocationLabel.text = stations[indexPath.row].address
cell.numberOfRemainingBikeLabel.text = stations[indexPath.row].numberOfRemainingBikes
cell.printer = stations[indexPath.row].name
cell.mapBtn.tag = indexPath.row
cell.mapBtn.addTarget(self, action: #selector(moveToMapPage), for: .touchUpInside)
return cell
}
func moveToMapPage(sender: UIButton) {
self.performSegue(withIdentifier: "toMap", sender: self)
let nameToPass = stations[sender.tag].name
mapPage.stationName = nameToPass
}
}
there is a UIButton in my tableView cell
class MainPageCell: UITableViewCell {
var printer: String!
let mapPage = MapViewController()
#IBOutlet weak var stationNameLabel: UILabel!
#IBOutlet weak var mapBtn: UIButton!
#IBOutlet weak var stationLocationLabel: UILabel!
#IBOutlet weak var numberOfRemainingBikeLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
mapBtn.addTarget(self, action: #selector(mapBtnTapped), for: .touchUpInside)
}
func mapBtnTapped (sender: UIButton) {
print (printer)
}
}
and this is my other vc
class MapViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate {
#IBOutlet weak var mapView: MKMapView!
var stationName: String = ""
override func viewDidLoad() {
super.viewDidLoad()
self.title = stationName
}
}
I will elaborate my problem that i am now facing here !
the thing I want to do is when I tap the button in tableView cell, I want to go to MapViewController and make the title of this vc "the station name" in the same cell.
so in VC with tableView, in cellforRowAt function I called addTarget.
with moveToMapPage function
but when I tapped the button and goes to MapView VC, the stationName is still nil
I have no clue what goes wrong,
any hints are appreciated
mapPage is not the instance that you are navigating to, so you're setting a variable on an unrelated controller.
You need to use prepare(for segue... if you want to get a link to the new controller
override func prepare(for segue: UIStoryboardSegue, sender: Any?)
{
// if you have multiple segues, you can set up different actions for each
if segue.identifier == "segueToMap"
{
let mapPage : MapViewController = segue.destination as! MapViewController
let mapPage : MapViewController = segue.destination as! MapViewController
mapPage.stationName = nameToPass
mapPage.delegate = self // if required
}
}
use navigation controller
let vc = self.storyboard?.instantiateViewController(withIdentifier:"toMap") as! toMapViewController
vc.stationNam = stations[sender.tag].name
self.navigationController?.pushViewController(vc, animated: true)
I have a table layout inside a view which as a custom cell,The problem I'm facing is that the cells inside has a button i want to hide the button in cell on clicking it(only the one that is clicked should be hidden) how can i do thing in correct method?

}
#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
}
}
}
