I've been trying to use the custom cell in function when button is clicked. and update a label in that specific row using the function.
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = myTableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CardCell
cell.startcount.tag = indexPath.row
cell.startcount.addTarget(self, action: "startcount:", forControlEvents:UIControlEvents.TouchUpInside)
}
here is the function I'm using
func startcount(sender: AnyObject){
// create a reference of CardCell
// update the counter like cell.textcount.text = "\(counter)"
// in the specific row
}
My custom cell class :
import UIKit
class CardCell: UITableViewCell {
#IBOutlet weak var textcount: UILabel!
#IBOutlet weak var startcount: UIButton!
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
}
}
func startcount(sender: AnyObject){
let button = sender as UIButton
let indexPath = NSIndexPath(forRow:button.tag inSection:0)
let cell = tableView.cellForRowAtIndexPath(indexPath) as CardCell
// update cell
}
For Swift 4 and above
func startCount(sender : AnyObject) {
let button = sender as! UIButton
let indexPath = IndexPath(row:button.tag ,section:0)
let cell = tableView.cellForRow(at: indexPath) as! CardCell
// update cell
}

I currently have a table with a custom cell that contains a button and a label. Everything is working fine, the label displays the product name and the button responds to a button tap.
What I would like to be able to do is animate the width of the row/cell where the button was tapped.
Here is the code I currently have...
Main ViewController:
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate{
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "reusableCell", for: indexPath) as! CustomCell
let data = items[indexPath.row]
cell.displayProductName.text = data.productName
cell.buttonAction = { sender in
print("Button tapped...")
}
return cell
}
}
Custom Cell
class CustomCell: UITableViewCell {
var buttonAction: ((UIButton) -> Void)?
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
#IBAction func activeInactive(_ sender: UIButton) {
self.buttonAction?(sender)
}
}
Table View
How can I animate the width of the row where the button was tapped?
You could subclass UIButton and add an index property where you can store the represented index for the button:
import UIKit
class UIButtonWithIndex: UIButton {
var representedIndex: Int?
}
Then you should use this class in the storyboard instead UIButton.
After that add the button as an outlet in your cell and connect in in Interface Builder.
class CustomCell: UITableViewCell {
#IBOutlet weak var button: UIButtonWithIndex!
var buttonAction: ((UIButtonWithIndex) -> Void)?
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
#IBAction func activeInactive(_ sender: UIButtonWithIndex) {
self.buttonAction?(sender)
}
// Reset the represented index when reusing the cell
override func prepareForReuse() {
//Reset content view width
button.representedIndex = nil
}
}
Then when you dequeue the cell in cellForRowAt indexPath set the representedIndex property. Now in your buttonAction you should have the index of the row in which the button was tapped.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "reusableCell", for: indexPath) as! CustomCell
let data = items[indexPath.row]
cell.displayProductName.text = data.productName
cell.button.representedIndex = indexPath.item
cell.buttonAction = { sender in
print("Button tapped... \(sender.representedIndex)")
}
return cell
}
Once you have the index you can retrieve the cell with cellForRowAtIndexPath
I'd recommend to:
Create subview, let's call it "resizeableContentView"
Add "resizeableContentView" as a child to cell's "contentView"
Add your views to "resizeableContentView" as a child
Set .clearColor for cell and "contentView" background color if needed
Set width for "resizeableContentView" by action
Don't forget reset cell when it's reused
you can try this boilerplate code:
cell.buttonAction = { sender in
UIView.animate(withDuration: 0.5) {
cell.frame = CGRect(x: 0, y: 0, width: 150, height: 50)
}
}
I am doing project in swift 4. I created radiobutton class in tableview cell. I want to get cell index when click to which radio button. Please help me.
Edit: I just added my entire code. I could not solve my problem. All of the codes are as follows. I created a radio button class and gave it a radio button feature. I tried to integrate the radio button in the tableview and get the index of the cell when the button is clicked as below, but it gave libc++abi.dylib: terminating with uncaught exception of type NSException error.
import UIKit
class TVCIsGuvenligi: UITableViewCell {
lazy var radioButtonGroup: [RadioButton] = {
return [
btnRadioEvet,
btnRadioHayir,
]
}()
#IBOutlet var lblSoru: UILabel!
#IBOutlet var lblSoruAyrinti: UILabel!
#IBOutlet var lblEvet: UILabel!
#IBOutlet var lblHayır: UILabel!
#IBOutlet var btnRadioEvet: RadioButton!
#IBAction func btnRadioEvet(_ sender: RadioButton)
{
let indexPath = IndexPath.init(row: sender.tag, section: 0)
updateRadioButton(sender)
print("index \(indexPath)")
}
#IBOutlet var btnRadioHayir: RadioButton!
#IBAction func btnRadioHayir(_ sender: RadioButton)
{
let indexPath = IndexPath.init(row: sender.tag, section: 0)
updateRadioButton(sender)
print("index \(indexPath)")
}
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func updateRadioButton(_ sender: RadioButton){
radioButtonGroup.forEach { $0.isSelected = false }
sender.isSelected = !sender.isSelected
}
}
ViewController.swift
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellIs", for: indexPath) as! TVCIsGuvenligi
cell.lblSoru.text = myTitle[indexPath.row]
cell.lblSoruAyrinti.text = myTitle[indexPath.row]
cell.btnRadioEvet.tag = (indexPath.row)
cell.btnRadioEvet.addTarget(self, action: #selector(getter: cell.btnRadioEvet), for: UIControlEvents.touchUpInside)
print("current cell tag \(cell.btnRadioEvet.tag)")
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
//getting the index path of selected row
let indexPath = tableView.indexPathForSelectedRow
//getting the current cell from the index path
let currentCell = tableView.cellForRow(at: indexPath!)! as! TVCIsGuvenligi
//getting the text of that cell.
let currentItem = currentCell.lblSoru.text
print("current item \(currentItem)")
}
use,
currentCell.radioButton.tag = indexPath.row
And use this tag to get index on the radio button click
I have a TableViewCell class like this:
class CampaignsTableViewCell: UITableViewCell {
#IBOutlet weak var activateButton: UIButton!
#IBOutlet weak var titleCampaignPlaceholder: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
setUpButton()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
private func setUpButton(){
activateButton.backgroundColor = .clear
activateButton.layer.cornerRadius = 5
activateButton.layer.borderWidth = 1
activateButton.layer.borderColor = UIColor.blue.cgColor
}
}
And, in another class which is a ViewController I have my UITableView methods:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let rowNumber = indexPath.row
let cellIdentifier = "CampaignTableViewCell"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? CampaignsTableViewCell else {
fatalError("The dequeued cell is not an instance of TableViewCellController.")
}
cell.titleCampaignPlaceholder.text = campaignsArray[rowNumber].campaignName
return cell
}
I need to use my activateButton in my UITableView method in order to access to campaignsArray. I have another method which requieres values from that array, so I need that method is called every time activateButton is pressed from my UITableView.
Any idea ?
Thank you very much
What I like doing in those cases where you have a button inside your UITableViewCell is the following:
Give the cell a closure that is called when tapping on the button like so
class CampaignsTableViewCell: UITableViewCell {
... all your code....
// give your cell a closure that is called when the button is pressed
var onButtonPressed: ((_ sender: UIButton) -> ())?
#IBAction func buttonPressed(sender: UIButton) { // wire that one up in IB
onButtonPressed?(sender)
}
}
and then inside your TableViewController
let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! CampaignsTableViewCell
cell.titleCampaignPlaceholder.text = campaignsArray[rowNumber].campaignName
cell.onButtonPressed = { [weak self] sender in
// Do your magic stuff here
}
return cell
Hope that helps
Your cell will get that event, not tableView. What you need to do is:
Create protocol inside your cell:
protocol CampaignsTableViewProtocol{
func actionButtonPressed(row: Int)
}
class CampaignsTableViewCell: UITableViewCell {
#IBOutlet weak var activateButton: UIButton!
#IBOutlet weak var titleCampaignPlaceholder: UILabel!
// keep info about row
var rowIndex: Int = -1
// create delegate that will let your tableView about action button in particular row
var delegate : CampaignsTableViewProtocol?
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
setUpButton()
self. activateButton.addTarget(self, action: #selector(self.activatePressed), for: UIControlEvents.touchDown)
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func activatePressed(){
self.delegate?.actionButtonPressed(row :rowIndex)
}
private func setUpButton(){
activateButton.backgroundColor = .clear
activateButton.layer.cornerRadius = 5
activateButton.layer.borderWidth = 1
activateButton.layer.borderColor = UIColor.blue.cgColor
}
}
Your tableViewController needs to adopt this protocol:
class MyTableViewController: UITableViewDelegate, UITableViewDataSource, CampaignsTableViewProtocol {
// rest of the code
}
Also, you will need to implement delegate function in your tableViewController:
func actionButtonPressed(row: Int) {
// get campaign you need
let campaign = campaignsArray[row]
// rest of the code
}
I have a button (red color cross) in the UITableViewCell and on click of that button I want to get indexPath of the UITableViewCell.
Right now I am assigning tag to each of the button like this
cell.closeButton.tag = indexPath.section
and the on click of the button I get the indexPath.section value like this:
#IBAction func closeImageButtonPressed(sender: AnyObject) {
data.removeAtIndex(sender.tag)
tableView.reloadData()
}
Is this the right way of implementation or is there any other clean way to do this?
Use Delegates:
MyCell.swift:
import UIKit
//1. delegate method
protocol MyCellDelegate: AnyObject {
func btnCloseTapped(cell: MyCell)
}
class MyCell: UICollectionViewCell {
#IBOutlet var btnClose: UIButton!
//2. create delegate variable
weak var delegate: MyCellDelegate?
//3. assign this action to close button
#IBAction func btnCloseTapped(sender: AnyObject) {
//4. call delegate method
//check delegate is not nil with `?`
delegate?.btnCloseTapped(cell: self)
}
}
MyViewController.swift:
//5. Conform to delegate method
class MyViewController: UIViewController, MyCellDelegate, UITableViewDataSource,UITableViewDelegate {
//6. Implement Delegate Method
func btnCloseTapped(cell: MyCell) {
//Get the indexpath of cell where button was tapped
let indexPath = self.collectionView.indexPathForCell(cell)
print(indexPath!.row)
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("MyCell") as! MyCell
//7. delegate view controller instance to the cell
cell.delegate = self
return cell
}
}
How to get cell indexPath for tapping button in Swift 4 with button selector
#objc func buttonClicked(_sender:UIButton){
let buttonPosition = sender.convert(CGPoint.zero, to: self.tableView)
let indexPath = self.tableView.indexPathForRow(at:buttonPosition)
let cell = self.tableView.cellForRow(at: indexPath) as! UITableViewCell
print(cell.itemLabel.text)//print or get item
}
Try with the best use of swift closures : Simple, Quick & Easy.
In cellForRowAtIndexPath method:
let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCellIdentifier", for: indexPath) as! CustomCell
cell.btnTick.mk_addTapHandler { (btn) in
print("You can use here also directly : \(indexPath.row)")
self.btnTapped(btn: btn, indexPath: indexPath)
}
Selector Method for external use out of cellForRowAtIndexPath method:
func btnTapped(btn:UIButton, indexPath:IndexPath) {
print("IndexPath : \(indexPath.row)")
}
Extension for UIButton :
extension UIButton {
private class Action {
var action: (UIButton) -> Void
init(action: #escaping (UIButton) -> Void) {
self.action = action
}
}
private struct AssociatedKeys {
static var ActionTapped = "actionTapped"
}
private var tapAction: Action? {
set { objc_setAssociatedObject(self, &AssociatedKeys.ActionTapped, newValue, .OBJC_ASSOCIATION_RETAIN) }
get { return objc_getAssociatedObject(self, &AssociatedKeys.ActionTapped) as? Action }
}
#objc dynamic private func handleAction(_ recognizer: UIButton) {
tapAction?.action(recognizer)
}
func mk_addTapHandler(action: #escaping (UIButton) -> Void) {
self.addTarget(self, action: #selector(handleAction(_:)), for: .touchUpInside)
tapAction = Action(action: action)
}
}
In Swift 4 , just use this:
func buttonTapped(_ sender: UIButton) {
let buttonPostion = sender.convert(sender.bounds.origin, to: tableView)
if let indexPath = tableView.indexPathForRow(at: buttonPostion) {
let rowIndex = indexPath.row
}
}
You can also get NSIndexPath from CGPoint this way:
#IBAction func closeImageButtonPressed(sender: AnyObject) {
var buttonPosition = sender.convertPoint(CGPointZero, to: self.tableView)
var indexPath = self.tableView.indexPathForRow(atPoint: buttonPosition)!
}
Create a custom class of UIButton and declare a stored property like this and use it to retrieve assigned indexPath from callFroRowAtIndexPath.
class VUIButton: UIButton {
var indexPath: NSIndexPath = NSIndexPath()
}
This is the full proof solution that your indexPath will never be wrong in any condition. Try once.

Here is a full example that will answer your question.
In your cellForRow:
#import <objc/runtime.h>
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
setAssociatedObject(object: YOURBUTTON, key: KEYSTRING, value: indexPath)
}
#IBAction func closeImageButtonPressed(sender: AnyObject) {
let val = getAssociatedObject(object: sender, key: KEYSTROKING)
}
Here val is your indexPath object, your can pass any object like you can assign pass cell object and get it in button action.
try this:
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = (tableView.dequeueReusableCell(withIdentifier: "MainViewCell", forIndexPath: indexPath) as! MainTableViewCell)
cell.myButton().addTarget(self, action: Selector("myClickEvent:event:"), forControlEvents: .touchUpInside)
return cell
}
this function get the position of row click
#IBAction func myClickEvent(_ sender: Any, event: Any) {
var touches = event.allTouches()!
var touch = touches.first!
var currentTouchPosition = touch.location(inView: feedsList)
var indexPath = feedsList.indexPathForRow(atPoint: currentTouchPosition)!
print("position:\(indexPath.row)")
}
class MyCell: UICollectionViewCell {
#IBOutlet weak var btnPlus: UIButton!
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) ->
UITableViewCell {
cell.btnPlus.addTarget(self, action: #selector(increment_Action(sender:)),
for: .touchUpInside)
cell.btnPlus.tag = indexPath.row
cell.btnPlus.superview?.tag = indexPath.section
}
#objc func increment_Action(sender: UIButton) {
let btn = sender as! UIButton
let section = btn.superview?.tag ?? 0
let row = sender.tag
}
I put stepper both outlets and action into tableview cell and using protocol delegate to connect it to tableview. When i tapped stepper in first row, stepper value appear normaly in first row but its also appear in some random row. how to fix this?
TableViewCell
protocol ReviewCellDelegate{
func stepperButton(sender: ReviewTableViewCell)
}
class ReviewTableViewCell: UITableViewCell {
#IBOutlet weak var countStepper: UIStepper!
#IBOutlet weak var stepperLabel: UILabel!
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 stepperButtonTapped(sender: UIStepper) {
if delegate != nil {
delegate?.stepperButton(self)
stepperLabel.text = "x \(Int(countStepper.value))"
}
}
ViewController
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIdentifier = "reviewCell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! ReviewTableViewCell
var imageView: UIImageView?
let photoG = self.photos[indexPath.row]
imageView = cell.contentView.viewWithTag(1) as? UIImageView
//let layout = cell.goodiesImage
let tag = indexPath.row // +1
cell.tag = tag
photoG.fetchImageWithSize(CGSize(width: 1000, height: 1000), completeBlock: { image, info in
if cell.tag == tag {
imageView?.image = image
cell.goodiesImage.image = image
}
})
func stepperButton(sender: ReviewTableViewCell) {
if let indexPath = tableView.indexPathForCell(sender){
print(indexPath)
}
}
Reset the value of stepper while loading your cell. you can reset the cell property values in cell's prepareForReuse method. add the following method in your ReviewTableViewCell class.
override func prepareForReuse()
{
super.prepareForReuse()
countStepper.value = 0.0
}
In tableViewCell VC:
1 - add these field
var cellDelegate: cellProtocol?
var index: IndexPath?
2 - then add this in the delegate:
func onStepperClick(index: Int, sender: UIStepper)
3 - when you have dragged your stepper over as an action use this:
#IBAction func cellStepper(_ sender: UIStepper) {
cellDelegate?.onStepperClick(index: (index?.row)!, sender: sender)
sender.maximumValue = 1 //for incrementing
sender.minimumValue = -1 //for decrementing
//this will make sense later
}
In ViewController
1 - add these to the tableView function that has the cellAtRow variable.
cell.cellDelegate = self
cell.index = indexPath
2 - Use this instead of your stepperButton function
func onStepperClick(index: Int, sender: UIStepper) {
print(index)
if sender.value == 1.0{
//positive side of stepper was pressed
}else if sender.value == -1.0{
//negative side of stepper was pressed
}
sender.value = 0 //resetting to zero so sender.value produce different values on plus and minus
}
Hope this works for you
As mentioned by #A-Live, your component is being reused and so need to be updated.
So in your view controller:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIdentifier = "reviewCell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! ReviewTableViewCell
var imageView: UIImageView?
let photoG = self.photos[indexPath.row]
imageView = cell.contentView.viewWithTag(1) as? UIImageView
//let layout = cell.goodiesImage
let tag = indexPath.row // +1
cell.tag = tag
photoG.fetchImageWithSize(CGSize(width: 1000, height: 1000), completeBlock: { image, info in
if cell.tag == tag {
imageView?.image = image
cell.goodiesImage.image = image
}
})
cell.countStepper.value = XXX[indexPath.row].value; //Here you update your view
cell.stepperLabel.text = "x \(Int(cell.countStepper.value))" //And here
And
func stepperButton(sender: ReviewTableViewCell) {
if let indexPath = tableView.indexPathForCell(sender){
print(indexPath)
XXX[sender.tag].value = sender.counterStepper.value //Here you save your updated value
}
NOTE:
1.MY Cell class is just normal..All changes are in viewcontroller class
2.I have taken stepper and over it added ibAddButton with same constraint as ibStepper
class cell: UITableViewCell {
#IBOutlet weak var ibAddButton: UIButton!
#IBOutlet weak var ibStepper: UIStepper!
#IBOutlet weak var ibCount: UILabel!
#IBOutlet weak var ibLbl: UILabel!
}
1.define empty int array [Int]()
var countArray = [Int]()
2.append countArray with all zeros with the number of data u want to populate in tableview
for arr in self.responseArray{
self.countArray.append(0)
}
3.in cell for row at
func tableView(_ tableView: UITableView, cellForRowAt indexPath:
IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! cell
let dict = responseArray[indexPath.row] as? NSDictionary ?? NSDictionary()
cell.ibLbl.text = dict["name"] as? String ?? String()
if countArray[indexPath.row] == 0{
cell.ibAddButton.tag = indexPath.row
cell.ibStepper.isHidden = true
cell.ibAddButton.isHidden = false
cell.ibCount.isHidden = true
cell.ibAddButton.addTarget(self, action: #selector(addPressed(sender:)), for: .touchUpInside)
}else{
cell.ibAddButton.isHidden = true
cell.ibStepper.isHidden = false
cell.ibStepper.tag = indexPath.row
cell.ibCount.isHidden = false
cell.ibCount.text = "\(countArray[indexPath.row])"
cell.ibStepper.addTarget(self, action: #selector(stepperValueChanged(sender:)), for: .valueChanged)}
return cell
}
4.objc functions
#objc func stepperValueChanged(sender : UIStepper){
if sender.stepValue != 0{
countArray[sender.tag] = Int(sender.value)
}
ibTableView.reloadData()
}
#objc func addPressed(sender : UIButton){
countArray[sender.tag] = 1//countArray[sender.tag] + 1
ibTableView.reloadData()
}
