This is my class Designed.
open class SBCity: NSObject {
var CM_CityID:String = ""
var CM_CityName:String = ""
var CM_OrderBy:Int = 0
required public init(CM_CityID:String,CM_CityName:String,CM_OrderBy:Int) {
self.CM_CityID = CM_CityID
self.CM_CityName = CM_CityName
self.CM_OrderBy = CM_OrderBy
}
}
ViewController
In the ViewController I have the tableView contain the following three details in each cell. I just append the value in the class on my UITableView didSelect method.
var source:SBCity?
var destination:SBCity?
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if filterdata.count != 0 {
return filterdata.count
} else {
if tableView == FirstTable {
return ArrcityList.count
} else {
return ArrcityList.count
}
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView == FirstTable{
let cell = tableView.dequeueReusableCell(withIdentifier: "RecentCityCell") as! RecentCityCell
cell.cities = ArrcityList[indexPath.row]
return cell
}
//if tableView is not table1 then
if filterdata.count != 0 {
let cell2 = tableView.dequeueReusableCell(withIdentifier: "SourceCityCell")
as! SourceCityCell
cell2.cities = filterdata[indexPath.row]
return cell2
} else {
let cell2 = tableView.dequeueReusableCell(withIdentifier: "SourceCityCell")
as! SourceCityCell
cell2.cities = ArrcityList[indexPath.row]
return cell2
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if isSelectingSource {
if tableView == FirstTable{
let indexPath = tableView.indexPathForSelectedRow
let crrtCell = tableView.cellForRow(at: indexPath!) as! RecentCityCell
self.source = SBCity(CM_CityID: crrtCell.lblID.text!, CM_CityName: crrtCell.lblCity1.text!, CM_OrderBy: 0)
source = SBCity(CM_CityID: crrtCell.lblID.text!, CM_CityName: crrtCell.lblCity1.text!, CM_OrderBy: 0)
SourceCityName = crrtCell.lblCity1.text!
self.moveOnNextVc()
} else {
let indexPath = tableView.indexPathForSelectedRow
let crrtCell = tableView.cellForRow(at: indexPath!) as! SourceCityCell
self.source = SBCity(CM_CityID: crrtCell.lblID2.text!, CM_CityName: crrtCell.lblCity2.text!, CM_OrderBy: 0)
source = SBCity(CM_CityID: crrtCell.lblID2.text!, CM_CityName: crrtCell.lblCity2.text!, CM_OrderBy: 0)
SourceCityName = crrtCell.lblCity2.text!
self.moveOnNextVc()
}
} else if isSelectingDestination {
if tableView == FirstTable{
let indexPath = tableView.indexPathForSelectedRow
let crrtCell = tableView.cellForRow(at: indexPath!) as! RecentCityCell
self.destination = SBCity(CM_CityID: crrtCell.lblID.text!, CM_CityName: crrtCell.lblCity1.text!, CM_OrderBy: 0)
destination = SBCity(CM_CityID: crrtCell.lblID.text!, CM_CityName: crrtCell.lblCity1.text!, CM_OrderBy: 0)
DestinationCityName = crrtCell.lblCity1.text!
self.moveOnNextVc()
} else {
let indexPath = tableView.indexPathForSelectedRow
let crrtCell = tableView.cellForRow(at: indexPath!) as! SourceCityCell
self.destination = SBCity(CM_CityID: crrtCell.lblID2.text!, CM_CityName: crrtCell.lblCity2.text!, CM_OrderBy: 0)
destination = SBCity(CM_CityID: crrtCell.lblID2.text!, CM_CityName: crrtCell.lblCity2.text!, CM_OrderBy: 0)
DestinationCityName = crrtCell.lblCity2.text!
self.moveOnNextVc()
}
}
}
But it does not append the value in the class. it's showing nil every time. What's the wrong with the code?

I am new in swift and I am not able to get main tableview index on nested tableview button click
my code is like this
extension Section2QuestionsViewController: UITableViewDataSource, UITableViewDelegate

cell = tableSection2.dequeueReusableCell(withIdentifier: strCellID) as? Section2QuestionCell
}
let dictAppStats = arrFinancialYears[indexPath.row] as? [String:Any]
cell?.lblQuestionTitle.text = "\(indexPath.row + 1). \(dictAppStats?["question"] as? String ?? "")"
cell?.arrCourses = [Any]()
cell?.arrCourses = dictAppStats?["options"] as? [Any] ?? []
cell?.tableInsideHeightConstraints.constant = CGFloat(28 * (cell?.arrCourses.count ?? 0))
cell?.tableInside.reloadData()
return cell!

Button Click
#objc func btnOptionClick(_ sender: UIButton)
{
let index = IndexPath(row: sender.tag, section: 0)
let cell: InsideSection2QuestionCell = tableInside.cellForRow(at: index) as! InsideSection2QuestionCell
let QuestionId = cell.lblQuestionId.text
let AnswwerId = cell.lblAnswerId.text
print(QuestionId as Any)
print(AnswwerId as Any)
Globalnewdict = ["option":AnswwerId as Any,"question":QuestionId as Any]
Globalindexvalue = sender.tag
NotificationCenter.default.post(name: Notification.Name(rawValue: "disconnectPaxiSockets"), object: nil)
tableInside.reloadData()
}
I am not able to get main tableview index path value on button. Is there is any way to get main tableview index path value on button click.
Please help
Thanks in Advance!
You could add an index path object in your Section2QuestionCell
var parentTableIndexPath : IndexPath!
Then set the value in cellForRowAt tableview delegate method
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let strCellID = "Section2QuestionCell"
var cell = tableView.dequeueReusableCell(withIdentifier: strCellID) as? Section2QuestionCell
if cell == nil {
tableSection2.register(Section2QuestionCell.self, forCellReuseIdentifier: strCellID)
cell = tableSection2.dequeueReusableCell(withIdentifier: strCellID) as? Section2QuestionCell
}
cell.parentTableIndexPath = indexPath
let dictAppStats = arrFinancialYears[indexPath.row] as? [String:Any]
cell?.lblQuestionTitle.text = "\(indexPath.row + 1). \(dictAppStats?["question"] as? String ?? "")"
cell?.arrCourses = [Any]()
cell?.arrCourses = dictAppStats?["options"] as? [Any] ?? []
cell?.tableInsideHeightConstraints.constant = CGFloat(28 * (cell?.arrCourses.count ?? 0))
cell?.tableInside.reloadData()
return cell!
}
Since btnOptionClick() is in same class, you can directly access the parent table Index path in your button action.
In
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let strCellID = "Section2QuestionCell"
var cell = tableView.dequeueReusableCell(withIdentifier: strCellID) as? Section2QuestionCell
if cell == nil
{
tableSection2.register(Section2QuestionCell.self, forCellReuseIdentifier: strCellID)
cell = tableSection2.dequeueReusableCell(withIdentifier: strCellID) as? Section2QuestionCell
}
let dictAppStats = arrFinancialYears[indexPath.row] as? [String:Any]
cell?.lblQuestionTitle.text = "\(indexPath.row + 1). \(dictAppStats?["question"] as? String ?? "")"
cell?.arrCourses = [Any]()
cell?.arrCourses = dictAppStats?["options"] as? [Any] ?? []
cell?.tableInsideHeightConstraints.constant = CGFloat(28 * (cell?.arrCourses.count ?? 0))
cell?.tableInside.tag = indexPath.row
cell?.tableInside.reloadData()
return cell!
}
In ButtonClick
#objc func btnOptionClick(_ sender: UIButton)
{
let index = IndexPath(row: sender.tag, section: 0)
let cell: InsideSection2QuestionCell = tableInside.cellForRow(at: index) as! InsideSection2QuestionCell
let QuestionId = cell.lblQuestionId.text
let AnswwerId = cell.lblAnswerId.text
print(QuestionId as Any)
print(AnswwerId as Any)
Globalnewdict = ["option":AnswwerId as Any,"question":QuestionId as Any]
Globalindexvalue = tableInside.tag
NotificationCenter.default.post(name: Notification.Name(rawValue: "disconnectPaxiSockets"), object: nil)
tableInside.reloadData()
}
In cellForRowAt I set indexpath.row to tableview.tag.
Then on button click I set tableview.tag to global indexpath.
I have implemented the following code to add expand/collapse feature to UITableView sections. When user click each section1, it expands and when we click the same section1 it collapses. But, I want the section1 to collapse, if I am expanding section2. How can I implement this feature to my code added below.
struct FaqData{
var faqHead = String()
var faqImage = String()
var questionArray : [(question : String, answer : String, answerurl : String)] = [(String,String,String)]()
var openSection = Bool()
}
var supportArray = [FaqData]()
func numberOfSections(in tableView: UITableView) -> Int {
return supportArray.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0{
return 1
}
else{
if supportArray[section].openSection == true{
return supportArray[section].questionArray.count + 1
}else{
return 1
}
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
tableView.separatorStyle = UITableViewCell.SeparatorStyle.none
if indexPath.section == 0{
let cell = tableView.dequeueReusableCell(withIdentifier: "SupportCenterID", for: indexPath) as! SupportCenterTableViewCell
cell.selectionStyle = UITableViewCell.SelectionStyle.none
cell.faqCollection.reloadData()
return cell
}
else{
if indexPath.row == 0{
let cell = tableView.dequeueReusableCell(withIdentifier: "SupportFaqID") as! SupportCenterFaqTableViewCell
cell.selectionStyle = UITableViewCell.SelectionStyle.none
let faqHead = supportArray[indexPath.section].faqHead
cell.imageText.text = faqHead.capitalized
cell.imageButton.setImage(UIImage(named: supportArray[indexPath.section].faqImage), for: .normal)
return cell
}
else{
let cell = tableView.dequeueReusableCell(withIdentifier: "QuestionID") as! SupportQuestionTableViewCell
cell.selectionStyle = UITableViewCell.SelectionStyle.none
cell.isSelected = true
cell.questionLabel.text = "Q.\(indexPath.row) " + supportArray[indexPath.section].questionArray[indexPath.row - 1].question
cell.answerLabel.text = supportArray[indexPath.section].questionArray[indexPath.row - 1].answer
print(supportArray[indexPath.section].questionArray[indexPath.row - 1].answerurl)
if supportArray[indexPath.section].questionArray[indexPath.row - 1].answerurl == ""{
cell.urlButton.isHidden = true
}
else{
cell.urlButton.isHidden = false
}
cell.urlButton.isHidden = true
cell.urlButton.tag = indexPath.row
UserDefaults.standard.set(indexPath.section, forKey: "SectionValue")
cell.urlButton.addTarget(self, action: #selector(urlButtonClicked(_:)), for: .touchUpInside)
cell.layoutMargins = UIEdgeInsets.zero
return cell
}
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if supportArray[indexPath.section].openSection == true{
if indexPath.section != 0{
if indexPath.row == 0{
let cell = tableView.cellForRow(at: indexPath) as! SupportCenterFaqTableViewCell
cell.faqView.backgroundColor = .white
cell.imageButton.tintColor = UIColor(hexString: "#D71B61")
cell.imageText.textColor = UIColor(hexString: "#D71B61")
}
}
supportArray[indexPath.section].openSection = false
let sections = IndexSet.init(integer: indexPath.section)
tableView.reloadSections(sections, with: .fade)
}
else{
supportArray[indexPath.section].openSection = true
let sections = IndexSet.init(integer: indexPath.section)
tableView.reloadSections(sections, with: .fade)
if indexPath.section != 0{
if indexPath.row == 0{
let cell = tableView.cellForRow(at: indexPath) as! SupportCenterFaqTableViewCell
cell.faqView.backgroundColor = UIColor(hexString: "#D71B61")
cell.imageButton.tintColor = .white
cell.imageText.textColor = .white
}
}
}
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
Can anyone provide a solution for this?
do this in didselecterow method. This is the else case of your condition
// You will need to reload multiple sections. So make an array.
var reloadSections = [Int]()
// find already opened array
if let alreadyOpenSection = supportArray.firstIndex(where: { (faq) -> Bool in
return faq.openSection
}) {
// if found, toggle the openSections bit
supportArray[alreadyOpenSection].openSection = false
// add it to reload sections array
reloadSections.append(alreadyOpenSection)
}
supportArray[indexPath.section].openSection = true
reloadSections.append(indexPath.section)
// create index set with reload sections array
let sections = IndexSet.init(reloadSections)
tableView.reloadSections(sections, with: .fade)
// below code is same
if indexPath.section != 0{
if indexPath.row == 0{
let cell = tableView.cellForRow(at: indexPath) as! SupportCenterFaqTableViewCell
cell.faqView.backgroundColor = UIColor(hexString: "#D71B61")
cell.imageButton.tintColor = .white
cell.imageText.textColor = .white
}
}
I have 5 types of tableview cells.And i ave one basecell.
BaseCell:-
import UIKit
class BaseCell: UITableViewCell {
// MARK: Internal Properties
var type: CellType!
var textChangedBlock: ((String) -> Void)?
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
func setOptions(Options1:NH_OptionsModel){}
func setOptions(OptionsSelected:NH_OptionsModel){}
func setOptions1(OptionsSelected:NH_OptionsModel){}
func setOptions(OptionsisSelected:NH_OptionsModel){}
func setOptions1(OptionsisSelected:NH_OptionsModel){}
}
One Tableviewcell:-
class RadioTypeCell: BaseCell {
var actionBlock: (() -> Void)?
#IBOutlet weak var optionLabel: UILabel?
#IBOutlet weak var buttonType: UIButton?
override func setOptions(Options1:NH_OptionsModel) {
self.optionLabel?.text = Options1.values
}
override func setOptions1(OptionsSelected:NH_OptionsModel) {
self.buttonType?.isHidden = false
buttonType?.setBackgroundImage(UIImage(named: "radio_check.png"), for: .normal)
print(OptionsSelected.isSelected)
OptionsSelected.isSelected = true
print(OptionsSelected.isSelected)
}
override func setOptions(OptionsisSelected:NH_OptionsModel) {
self.buttonType?.isHidden = false
buttonType?.setBackgroundImage(UIImage(named: "radio_uncheck.png"), for: .normal)
print(OptionsisSelected.isSelected)
OptionsisSelected.isSelected = false
print(OptionsisSelected.isSelected)
}
#IBAction func onActionButton(btn: UIButton) {
print("click the cell")
actionBlock?()
}
override func awakeFromNib() {
super.awakeFromNib()
}
override func prepareForReuse() {
super.prepareForReuse()
}
}
In viewcontroller:-
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let model = questionViewModel.titleForHeaderInSection(atsection: indexPath.section)
print(model.answerType)
print(model.answerType?.rawValue)
let c = model.answerType
let cellClass = c?.cellType().getClass()
print(cellClass)
let cell = tableView.dequeueReusableCell(withIdentifier: (cellClass?.cellReuseIdentifier())!, for: indexPath) as! BaseCell
print(cell)
let optionModel = questionViewModel.datafordisplay(atindex: indexPath)
cell.setOptions(Options1: optionModel)
cell.type = c?.cellType()
currentCell(c: cell, index: indexPath.row)
return cell
}
So In the tableview cell ,it contain
the following things.
1.One button
2.Label(Here showing the options)
So while selecting the one option i will click on the button,at that time the button has set the background image.Initially the image will be radio button with uncheck after while clicking the button the button image becomes radio button check.
And i given the code in the didselect the cell from the tableview.
Now my problem is after selecting the cells and then scrolling the tableview .The cells content is not refreshing .How to solve the problem.
And my tableview has sections.
My model:-
import UIKit

Make sure your model object value is update on button clicked event and you need to update cell ui in Cell at index.
Here is reference code for how to update ui at cell at index.
Note: Code is not checked in xcode so may be some minor error.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let model = questionViewModel.titleForHeaderInSection(atsection: indexPath.section)
print(model.answerType)
print(model.answerType?.rawValue)
let c = model.answerType
let cellClass = c?.cellType().getClass()
print(cellClass)
let cell = tableView.dequeueReusableCell(withIdentifier: (cellClass?.cellReuseIdentifier())!, for: indexPath) as! BaseCell
print(cell)
let optionModel = questionViewModel.datafordisplay(atindex: indexPath)
cell.setOptions(Options1: optionModel)
if optionModel.isSelected {
cell.setOptions1(OptionsisSelected:optionModel)
} else {
cell.setOptions(OptionsisSelected:optionModel)
}
cell.type = c?.cellType()
currentCell(c: cell, index: indexPath.row)
return cell
}
In this i am having three sections in a table view in which first section will have addresses and radio buttons if i click on radio button it will active and the particular address will be posting depending on the address selection the third section needs to call the api and load the data in the second table view which is present in third section here the problem is during loading for first time when app launched in simulator it is not loading the third section cell data can any one help me how to reduce the error ?
here is the code for table view class

and the first time image loading is shown below
!enter image description here ]1
and if i select another radio button in first section it was working fine as expected and image is shown below
I need to get the text from the textfield i.e from KgCustomCell and KgRepsCustomCell. I need to fetch the data from the field, when i run the buttonClicked method.
I have tried to add to instance variables, which contains kg and reps, but the first time i click the button, it's empty. The second time it's okay. But how can i load the data in the most correct way?
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let index = indexPath.row
if indexPath.row == 0 && indexPath.section == 0 {
let exerciseName = tableView.dequeueReusableCellWithIdentifier("Exercise Name", forIndexPath: indexPath) as! LoggedExerciseNameCell
exerciseName.lblExerciseName.text = self.exercise?.name
return exerciseName
}
if index == 0 && indexPath.section == 1 {
let txtFieldKg = tableView.dequeueReusableCellWithIdentifier("Text KG", forIndexPath: indexPath) as! KgCustomCell
return txtFieldKg
}
if index == 1 && indexPath.section == 1 {
let txtFieldReps = tableView.dequeueReusableCellWithIdentifier("Text Reps", forIndexPath: indexPath) as! KgRepsCustomCell
//kg = txtFieldReps.textReps.text
return txtFieldReps
}
if index == 2 && indexPath.section == 1 {
let btnLog = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath) as! ButtonLogWorkoutCustomCell
btnLog.btnLogExercise.addTarget(self, action: #selector(AddLogViewController.buttonClicked(_:)), forControlEvents: UIControlEvents.TouchUpInside)
// kg = txtFieldReps.textReps.text
return btnLog
}
if indexPath.section == 2 {
let loggedExerciseInformation = tableView.dequeueReusableCellWithIdentifier("Logged Exercise", forIndexPath: indexPath) as! LoggedExerciseCustomCell
return loggedExerciseInformation
}
let noCell = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath)
return noCell
}
func buttonClicked(sender:UIButton) {
let button = sender as UIButton
if let superview = button.superview {
if (superview.superview as? ButtonLogWorkoutCustomCell) != nil {
try! LogManagerDAO.sharedInstance.realm.write({
exercise?.loggedKg = 4//Int(txtKG.text!)!
exercise?.loggedReps = 4//Int(txtReps.text!)!
log!.addExerciseToLog(exercise!)
loadLoggedExercise()
tableView.reloadData()
})
}
}
}
If you just want the text of that textField than you can use delegate method of UITextField like this, first declare two instance var for that 2 textField's value
var strKG: String = ""
var strReps: String = ""
Now set delegate with textField in cellForRowAtIndexPath
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let index = indexPath.row
if indexPath.row == 0 && indexPath.section == 0 {
let exerciseName = tableView.dequeueReusableCellWithIdentifier("Exercise Name", forIndexPath: indexPath) as! LoggedExerciseNameCell
exerciseName.lblExerciseName.text = self.exercise?.name
return exerciseName
}
if index == 0 && indexPath.section == 1 {
let txtFieldKg = tableView.dequeueReusableCellWithIdentifier("Text KG", forIndexPath: indexPath) as! KgCustomCell
txtFieldReps.textField.tag = index
txtFieldKg.textField.delegate = self
return txtFieldKg
}
if index == 1 && indexPath.section == 1 {
let txtFieldReps = tableView.dequeueReusableCellWithIdentifier("Text Reps", forIndexPath: indexPath) as! KgRepsCustomCell
txtFieldReps.textField.tag = index
txtFieldReps.textField.delegate = self
return txtFieldReps
}
if index == 2 && indexPath.section == 1 {
let btnLog = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath) as! ButtonLogWorkoutCustomCell
btnLog.btnLogExercise.addTarget(self, action: #selector(AddLogViewController.buttonClicked(_:)), forControlEvents: UIControlEvents.TouchUpInside)
// kg = txtFieldReps.textReps.text
return btnLog
}
if indexPath.section == 2 {
let loggedExerciseInformation = tableView.dequeueReusableCellWithIdentifier("Logged Exercise", forIndexPath: indexPath) as! LoggedExerciseCustomCell
return loggedExerciseInformation
}
let noCell = tableView.dequeueReusableCellWithIdentifier("Button Log", forIndexPath: indexPath)
return noCell
}
Now add delegate method of UITextField
func textFieldDidEndEditing(textField: UITextField) {
if(textField.tag == 0) {
self.strKG = textField.text
}
else {
self.strReps = textField.text
}
}
Now just use this two string object in your button action method.
