How to get textLabel of selected row in swift? - uitableview

Question

So i am trying to get the value of the textLabel of the row I select. I tried printing it, but it didn't work. After some research I found out that this code worked, but only in Objective-C;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"did select and the text is %#",[tableView cellForRowAtIndexPath:indexPath].textLabel.text);]
}
I could not find any solution for Swift. Printing the indexpath.row is possible though, but that is not what I need.
so what should I do? or what is the 'Swift-version' of this code?

Answer 1

Try this:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let indexPath = tableView.indexPathForSelectedRow() //optional, to get from any UIButton for example
let currentCell = tableView.cellForRowAtIndexPath(indexPath) as UITableViewCell
print(currentCell.textLabel!.text)

If you're in a class inherited from UITableViewController, then this is the swift version:
override func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
let cell = self.tableView.cellForRowAtIndexPath(indexPath)
NSLog("did select and the text is \(cell?.textLabel?.text)")
}
Note that cell is an optional, so it must be unwrapped - and the same for textLabel. If any of the 2 is nil (unlikely to happen, because the method is called with a valid index path), if you want to be sure that a valid value is printed, then you should check that both cell and textLabel are both not nil:
override func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
let cell = self.tableView.cellForRowAtIndexPath(indexPath)
let text = cell?.textLabel?.text
if let text = text {
NSLog("did select and the text is \(text)")
}
}

Swift 4
To get the label of the selected row:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath) as! TableViewCell
print(cell.textLabel?.text)
}
To get the label of the deselected row:
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath) as! TableViewCell
print(cell.textLabel?.text)
}

If you want to print the text of a UITableViewCell according to its matching NSIndexPath, you have to use UITableViewDelegate's tableView:didSelectRowAtIndexPath: method and get a reference of the selected UITableViewCell with UITableView's cellForRowAtIndexPath: method.
For example:
import UIKit
class TableViewController: UITableViewController {
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 4
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
switch indexPath.row {
case 0: cell.textLabel?.text = "Bike"
case 1: cell.textLabel?.text = "Car"
case 2: cell.textLabel?.text = "Ball"
default: cell.textLabel?.text = "Boat"
}
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let selectedCell = tableView.cellForRowAtIndexPath(indexPath)
print(selectedCell?.textLabel?.text)
// this will print Optional("Bike") if indexPath.row == 0
}
}
However, for many reasons, I would not encourage you to use the previous code. Your UITableViewCell should only be responsible for displaying some content given by a model. In most cases, what you want is to print the content of your model (could be an Array of String) according to a NSIndexPath. By doing things like this, you will separate each element's responsibilities.
Thereby, this is what I would recommend:
import UIKit
class TableViewController: UITableViewController {
let toysArray = ["Bike", "Car", "Ball", "Boat"]
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return toysArray.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
cell.textLabel?.text = toysArray[indexPath.row]
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let toy = toysArray[indexPath.row]
print(toy)
// this will print "Bike" if indexPath.row == 0
}
}
As you can see, with this code, you don't have to deal with optionals and don't even need to get a reference of the matching UITableViewCell inside tableView:didSelectRowAtIndexPath: in order to print the desired text.

In my case I made small changes, when i search the value in tabelview select (didSelectRowAtIndexPath) the cell its return the index of the cell so im get problem in move one viewControler to another.By using this method i found a solution to redirect to a new viewControler
let indexPath = tableView.indexPathForSelectedRow!
let currentCellValue = tableView.cellForRow(at: indexPath!)! as UITableViewCell
let textLabelText = currentCellValue.textLabel!.text
print(textLabelText)

Answer 6

In swift 4 :
by overriding method
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let storyboard = UIStoryboard(name : "Main", bundle: nil)
let next vc = storyboard.instantiateViewController(withIdentifier: "nextvcIdentifier") as! NextViewController
self.navigationController?.pushViewController(prayerVC, animated: true)
}

Answer 7

This will work:
let item = tableView.cellForRowAtIndexPath(indexPath)!.textLabel!.text!

Answer 8

Maintain an array which stores data in the cellforindexPath method itself :-
[arryname objectAtIndex:indexPath.row];
Using same code in the didselectaAtIndexPath method too.. Good luck :)
