At present i am getting only one value, how can i get if i selected multiple check buttons
Fix this portion of your code:
if selectedRows.contains(indexPath)
{
cell.checkBtn.setImage(UIImage(named:"check"), for: .normal)
UserDefaults.standard.set(cell.tittleLbl.text, forKey: "tittle")
}
else
{
cell.checkBtn.setImage(UIImage(named:"uncheck"), for: .normal)

My problem is that when I open and close other sections after clicking on the checkboxes, unselected checkboxes in other sections appear as selected and selected ones are unselected. What should I do? Can you show me some code? Thanks!

Looks like your configuration works wrong and when you toggle your cell old data applied to your cell. So you need to clear all your data in prepareFroReuse() method inside your UIColelctionViewCell class

I have a tableview with 3 collapsible sections. users can only select rows in section 3 and when they select it goes green. However, when this section is collapsed all the selections are forgotten and when I re-open the section, usually the first row is always green (though it shouldn't be). Sometimes, other sections end up being green too when they shouldn't - not sure what I've got wrong?

The key thing to understand here is that the Cells are Reused when you say
let cell = tableView.dequeueReusableCell(withIdentifier: "tableCell", for: indexPath) as! CustomTableCell
dequeueReusableCell basically reuses a previously loaded UITableViewCell and in your case you changed the background color of the cell to green
To get a better understanding of the concept consider reading some articles like this one on Reusing Cells
Changes in Code
What you should do considering the above in mind
var backgroundColors = [UIColor](repeating: UIColor.white, count: 10)
you have to save the state of the colors in a model (ideally you should make a custom struct)
now in cellForRowAt add this
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "tableCell", for: indexPath) as! CustomTableCell
.
.
cell.backgroundColor = backgroundColors[indexPath.row]
// **EDIT**
let cellShouldBeSelected = backgroundColors[indexPath.row] == .green
if cellShouldBeSelected {
tableView.selectRow(at: indexPath, animated: false, scrollPosition: .none)
}
.
.
return cell
}
And your didSelectRowAt and didDeselectRowAt should update the model
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.backgroundColors[indexPath.row] = .green
tableView.reloadRows(at: [indexPath], with: .none)
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
if (self.backgroundColors[indexPath.row] == .green) {
self.backgroundColors[indexPath.row] = .white
tableView.reloadRows(at: [indexPath], with: .none)
}
}
On second thought
Solution 2 (Recommended)
From you comments, i see you only need one selected cell at one time, assuming that keeping an array of backgroundColors is just a bad idea.
declare a int for the selected index
// -1 representing nothing is selected in the beginning
var selectedRow = -1
now your cellForRowAt will look like
let cell = tableView.dequeueReusableCell(withIdentifier: "tableCell", for: indexPath) as! CustomTableCell
.
.
if indexPath.section == 2, indexPath.row == self.selectedRow {
cell.backgroundColor = .green
} else {
cell.backgroundColor = .white
}
.
.
return cell
}
And your didSelectRowAt
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if indexPath.section == 2 {
self.selectedRow = indexPath.row
tableView.reloadSections([2], with: .automatic)
}
}
And now you can remove didDeselectRowAt completely
Good time of day, in my app i have a tableview and custom cell, in cell there are labels, button and progressBar, so that when i tap button download proceeds and progressBar shows progress, but when i scroll down i realise that there are other cells are selected and shows progress and when i scroll up again progress of my selected cell stops. Could you help, any feedbacks appreciated )
That's my TableViewController :
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return titles.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ViewControllerTableViewCell
cell.pesnya.text = titles[indexPath.row]
cell.pevets.text = artists[indexPath.row]
cell.url = urls[indexPath.row]
return (cell)
}
#IBAction func buttonPressed(_ sender: AnyObject) {
(sender as! UIButton).isSelected = !(sender as! UIButton).isSelected
if (sender as! UIButton).isSelected {
if let indexPath = tableView.indexPath(for: sender.superview!?.superview as! UITableViewCell) {
DownloadManager.shared.download(url: urls[indexPath.row], title: titles[indexPath.row])
}
} else {
// (sender as! UIButton).setTitle("Удалить", for: UIControlState.normal)
if let indexPath = tableView.indexPath(for: sender.superview!?.superview as! UITableViewCell) {
let name = "\(titles[indexPath.row]).mp3"
let name2 = name.replacingOccurrences(of: " ", with: "")
let filePathURL = URL(string:"string")
do {
try FileManager.default.removeItem(at: filePathURL!)
} catch {
print("Could not delete file: \(error)")
}
}
}
}
This is because table view cell will be reused when you scroll. Set views to initial status in cell's prepareForReuse. Like this:
class ACell: UITableViewCell {
override func prepareForReuse() {
view.hidden = true
}
}
try this :-
override func tableView(_ tableView: UITableView, numberOfRowsInSection
section: Int) -> Int
{
return titles.count
}
override func tableView(_ tableView: UITableView, cellForRowAt
indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for:
indexPath) as! ViewControllerTableViewCell
cell.pesnya.text = titles[indexPath.row]
cell.pevets.text = artists[indexPath.row]
cell.url = urls[indexPath.row]
// Create IBOutlet for button
cell.btnPressed.tag = indexPath.row
cell.btnPressed.addTarget(self, action: #selector(self.buttonPressed(sender:)), for: .touchUpInside)
if cell.btnPressed.isSelected {
DownloadManager.shared.download(url: urls[indexPath.row], title: titles[indexPath.row])
}else {
let name = "\(titles[indexPath.row]).mp3"
let name2 = name.replacingOccurrences(of: " ", with: "")
let filePathURL = URL(string:"string")
do {
try FileManager.default.removeItem(at: filePathURL!)
} catch {
print("Could not delete file: \(error)")
}
}
return (cell)
}
#IBAction func buttonPressed(_ sender: UIButton) {
let indexPath = IndexPath(row: sender.tag, section: 0)
if let cell = tableView.cellForRow(at: indexPath) as?
ViewControllerTableViewCell {
cell.btnPressed.isSelected = !cell.btnPressed.isSelected
tableview.reloadData()
}
}
I would like that users can choose maximum one voice. And that the checkmark jumps to where you tapt and deselect the other.
It looks like very simple, but I don't see the solution. And I can't find the answer on the internet.
Please can anybody help me?
Thanks advance!

Simple change of function cellForRow:atIndexPathshould work:

//Name
let voice = speechVoices[indexPath.row]
let voiceLang = voice.language as? String

}
else {
cell.detailTextLabel?.text = ""
}
cell.detailTextLabel?.textColor = UIColor.gray
// Checkmark
if(theVoice != nil && theVoice == voiceLang) {
cell.accessoryType = .checkmark
} else {
cell.accessoryType = .none
}
return cell
}
UPD#1
But you can use better solution:
1) Add property fileprivate var selectedIndexPath: IndexPath?
2) Change function func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath)to next one:
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
//Name
let voice = speechVoices[indexPath.row]
let voiceLang = voice.language as? String
let theVoice = UserDefaults.standard.object(forKey:"voice") as? String
cell.textLabel?.text = voice.name
// Language
if let language = countryName(countryCode: voice.language) {
cell.detailTextLabel?.text = "\(language)"
}
else {
cell.detailTextLabel?.text = ""
}
cell.detailTextLabel?.textColor = UIColor.gray
// Checkmark
cell.accessoryType = self.selectedIndexPath == indexPath ? .checkmark : .none
return cell
}
3) And then in func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) you can do next:
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let voice = speechVoices[indexPath.row]
self.selectedIndexPath = indexPath
UserDefaults.standard.set(voice.language, forKey:"voice")
UserDefaults.standard.synchronize()
tableView.deselectRow(at: indexPath, animated: true)
tableView.reloadRows(at: [indexPath], with: .automatic)
}
