check / uncheck the check box by tapping the cell in table view and how to know which cell has checked or unchecked inside Expandable drop down in Swift.
VBExpandVC
class VBExpandVC: UIViewController,UITableViewDelegate,UITableViewDataSource {
@IBOutlet var myTableView: UITableView!
struct Notification:Codable {
let notification:[Headings]
}
struct Headings:Codable {
var name:String
var status:Int

var names = [Headings]()
var expandTableview:VBHeader = VBHeader()
var cell : VCExpandCell!

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
expandTableview = Bundle.main.loadNibNamed("VBHeader", owner: self, options: nil)?[0] as! VBHeader
let layer = expandTableview.viewHeader.layer
layer.shadowColor = UIColor.black.cgColor
layer.shadowOffset = CGSize(width: 0, height: 1)
layer.shadowOpacity = 0.4
expandTableview.lblDate.text = self.names[section].name
expandTableview.btnExpand.tag = section
expandTableview.btnExpand.addTarget(self, action: #selector(VBExpandVC.headerCellButtonTapped(_sender:)), for: UIControl.Event.touchUpInside)
let str:String = "\(self.names[section].status)"//arrStatus[section] as! String
if str == "0"
{
UIView.animate(withDuration: 2) { () -> Void in
self.expandTableview.imgArrow.image = UIImage(named :"switch")
}
}
else
{
UIView.animate(withDuration: 2) { () -> Void in
self.expandTableview.imgArrow.image = UIImage(named :"switch2")
}
}
return expandTableview
}
@objc func headerCellButtonTapped(_sender: UIButton)
{
print("header tapped at:")
print(_sender.tag)
var str:String = "\(self.names[_sender.tag].status)"
if str == "0"
{
self.names[_sender.tag].status = 1
}
else
{
self.names[_sender.tag].status = 0
}
// myTableView.reloadData()
myTableView.reloadSections([_sender.tag], with: .none)
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat
{
//Return header height as per your header hieght of xib
return 40
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
let str:Int = (names[section].status)
if str == 0
{
return 0
}
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as? VCExpandCell
return cell;
}
func numberOfSections(in tableView: UITableView) -> Int
{
return self.names.count
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
{
//Return row height as per your cell in tableview
return 111
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("selected:\(indexPath.section)")
}
// getNotifications
func getNotifications(){
guard let url = URL(string: "https://www.json-generator.com/api/json/get/cgAhRPmZgy?indent=2") else {
return
}
var request = URLRequest(url: url)
request.httpMethod = "GET"
URLSession.shared.dataTask(with: request, completionHandler: { (data, response, error) in
guard let data = data, error == nil, response != nil else {
return
}
do {
let headings = try JSONDecoder().decode(Notification.self, from: data)
self.names = headings.notification
DispatchQueue.main.async {
self.myTableView.reloadData()
}
} catch {
print(error)

}).resume()
}
// End
}
VCExpandCell
class VCExpandCell: UITableViewCell {
@IBOutlet weak var btnMobile: UIButton!
@IBOutlet weak var btnEmail: UIButton!
@IBOutlet weak var btnSms: 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
}
@IBAction func btnMobileApp(_ sender: UIButton) {
print("mobile app checked")
print(sender.tag)
if sender.isSelected {
sender.isSelected = false
} else {
sender.isSelected = true
}
}
@IBAction func btnSMS(_ sender: UIButton) {
print("sms checked")
print(sender.tag)
if sender.isSelected {
sender.isSelected = false
} else {
sender.isSelected = true
}
}
@IBAction func btnEmail(_ sender: UIButton) {
print("email checked")
print(sender.tag)
if sender.isSelected {
sender.isSelected = false
} else {
sender.isSelected = true
}
}
}
In the above code, I have two major problems.
-
selected check box positions are changing when expanded the section and expanded another section
-
Unable to find selected check boxes by tapping the cell in table view inside Expand drop down.
