How to deselect all buttons when one of them is selected - swift

Question

I have a tableview and inside one of my rows I have buttons. I want to deselect all buttons when one is selected and change the background color to the red when button is selected. I saw lots of example but I couldn't do it in my own code.
func configure(_ modelArray : [UnitAndColors], colorTitle:String, packingTitle:String) {
self.unitStackView.removeAllArrangedSubviews()
self.arrayUnitsAndColor?.removeAll()
self.arrayUnitsAndColor = modelArray
let filteredArray = self.arrayUnitsAndColor?.unique { $0.colorDesc }
var i : Int = 0
filteredArray?.forEach { units in
let vw = self.createUnits(units, tag: i)
self.unitStackView.addArrangedSubview(vw)
vw.snp.makeConstraints {
$0.size.equalTo(40.0)
}
i = i + 1
}
}
func createUnits(_ model : UnitAndColors, tag: Int) -> UIStackView {
let stackViewMain = UIStackView()
stackViewMain.axis = .horizontal
stackViewMain.spacing = 4
let labelPackingUnit = UIButton()
labelPackingUnit.backgroundColor = Colors().colorWhite
labelPackingUnit.tag = tag
labelPackingUnit.setTitleColor(Colors().colorRed, for: .normal)
labelPackingUnit.addTarget(self, action: #selector(selectUnit(_:)), for: .touchUpInside)
labelPackingUnit.titleLabel?.font = UIFont.fontBold16
labelPackingUnit.contentHorizontalAlignment = .center
labelPackingUnit.setBorder(width: 1, color: Colors().colorRed)
labelPackingUnit.setCornerRound(value: 20.0)
labelPackingUnit.setTitle(model.unitDesc, for: .normal)
stackViewMain.addArrangedSubview(labelPackingUnit)
labelPackingUnit.snp.makeConstraints {
$0.size.equalTo(40)
}
return stackViewMain
}
#objc private func selectButton(_ sender : UIButton) {
let tag : Int = sender.tag
guard let model : UnitAndColors = self.arrayUnitsAndColor?.filter({ $0.colorDesc == selectedColorName })[tag] else { return }
selectedUnit = model.unitDesc ?? ""
delegate?.changePrice(selectedPrice: model.modelPrice, arrayUnitsAndColor ?? [])
}

Answer 1

It's pretty frustrating to understand what's happening in your code, but I think that's what you're looking for:
#objc private func selectButton(_ sender : UIButton) {
let tag : Int = sender.tag
guard let model: UnitAndColors = self.arrayUnitsAndColor?.filter({ $0.colorDesc == selectedColorName })[tag] else { return }
selectedUnit = model.unitDesc ?? ""
for stackView in unitStackView.arrangedSubviews as? [UIStackView] ?? [] {
guard let button = stackView.arrangedSubviews.first as? UIButton else {
return
}
button.isSelected = false
button.backgroundColor = .clear
}
selectedUnit.isSelected = true
selectedUnit.backgroundColor = .red
delegate?.changePrice(selectedPrice: model.modelPrice, arrayUnitsAndColor ?? [])
}

var selectedRows: [Int] = [Int]()
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.allowMultipleSelection = true
}
func selectAll(){
for i in 0..<totalRows.count{
selectedRows.append(i)
let indexPath = IndexPath(row: i, section: 0)
self.tableView.selectRow(at: indexPath, animated: true, scrollPosition: .none)
}
}
func deselectAll(){
for i in 0..<totalRows.count{
selectedRows.append(i)
let indexPath = IndexPath(row: i, section: 0)
self.tableView.deselectRow(at: indexPath, animated: true)
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
selectedRows.append(indexPath.row)
print(selectedRows)
}
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
if let index = selectedRows.firstIndex(of: indexPath.row) {
selectedRows.remove(at: index)
}
print(selectedRows)
if selectedRows.isEmpty{
}
}
}
class TableViewCell: UITableViewCell{
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
if (selected) {
print("selected")
contentView.backgroundColor = .red
} else {
contentView.backgroundColor = .red
}
}
}
