How to get Label text of UITableView Cell using Swift? - arrays

Question

I want to make simple UITabelView. I registered it's cell with my custom class which named as backgroundviewcell. I want to get Label of the selected cell. I tried many times but the output is coming nil value. I have also tried solution from stack overflow but it does not work for me. This is my cellForRowAt indexPath code :
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> backgroundViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "soundElementalcell") as! backgroundViewCell
let imageNames = sections[indexPath.section].images[indexPath.row]
cell.Labeltittle.text = sections[indexPath.section].items[indexPath.row]
cell.Labeltittle.textColor = UIColor(hex : 0x90BA27)
cell.LabelDetail.text = sections[indexPath.section].detail[indexPath.row]
//cell.detailTextLabel?.textColor = UIColor.red
//cell.isHighlighted = false
cell.backgroundColor = UIColor.clear
cell.iconview.image = UIImage(named: imageNames)
return cell
}
This is my didSelectRowAt indexPath code :
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let indexPath = tableView.indexPathForSelectedRow!
let currentCell = tableView.cellForRow(at: indexPath)!
celltext = currentCell.textLabel!.text
performSegue(withIdentifier: "showPlayer", sender: self)
}
and my Segue Method is :
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showPlayer" {
let playerVC = segue.destination as! PlayerViewController
playerVC.trackName = (celltext)! as String
}
}

Answer 1

This is working for me:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath) as! YourCellType
let labelContent = cell.labelToAccess.text
}
First line creates an instance of your cell type (or standard cell, not my case).
The second saves the content of your label (labelToAccess in this case) in a constant.

Instead of accessing the text from the cell's label you need to access the array that you have used to fill the tableView's cell data.
So you need to use UITableViewDelegate method didSelectRowAtindexPath and access the array that you are using with your tableView methods.
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print(indexPath.row)
//Access the array that you have used to fill the tableViewCell
print(yourArray[indexPath.row])
}
Note: Once confirm that TableView delegate is properly connected with your ViewController so that it will call didSelectRowAt method when you select cell.
Edit: If you want to pass the data then try like this way.
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "showPlayer", sender: indexPath) //Pass indexPath as sender instead of self
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showPlayer" {
let playerVC = segue.destination as! PlayerViewController
let indexPath = sender as! IndexPath
playerVC.trackName = sections[indexPath.section].items[indexPath.row]
}
}

Try this 'Swift 4' -
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let currentCellTxt = yourTableView.cellForRow(at: indexPath)! as? YourCustomTableViewCell
print(currentCellTxt?.lblYourName?.text) // 'lblYourName' that you defined in your 'YourCustomTableViewCell'
}

Answer 4

You didn't set any text for textLabel. Hence it returns nil value.
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> backgroundViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "soundElementalcell") as! backgroundViewCell
let imageNames = sections[indexPath.section].images[indexPath.row]
cell.Labeltittle.text = sections[indexPath.section].items[indexPath.row]
cell.Labeltittle.textColor = UIColor(hex : 0x90BA27)
cell.LabelDetail.text = sections[indexPath.section].detail[indexPath.row]
//cell.detailTextLabel?.textColor = UIColor.red
//cell.isHighlighted = false
cell.backgroundColor = UIColor.clear
cell.iconview.image = UIImage(named: imageNames)
return cell
}
In didSelectRow func try to get value from Labeltittle.text not from textLabel.text
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let indexPath = tableView.indexPathForSelectedRow!
let currentCell = tableView.cellForRow(at: indexPath)!
celltext = currentCell.Labeltittle.text
performSegue(withIdentifier: "showPlayer", sender: self)
}
