How to get textLabel of selected row in swift?
Solution 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)
Solution 2
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)")
}
}
Solution 3
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 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)
}

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?
