Swift 5 UITableViewCell : Expand one section and collapse the expanded section - ios

Question

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?

Answer 1

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
}
}
