Swift Change the color of the custom label for the table label when you select

Question

I have a custom Tableview cell in swift, and a label in that cell.

I want to change the label when selecting a cell.

How can I reference my custom UITableviewCell label in didSelectRowAtIndexPath

In Objective-C, I would use the following to refer to my custom cell in didSelectRowAtIndexPath :

 MPSurveyTableViewCell *cell = (MPSurveyTableViewCell *)[tableViewcellForRowAtIndexPath:indexPath]; cell.customLabel.TextColor = [UIColor redColor]; 

What do I need to do quickly to achieve the same result?

Answer 1

You just need to translate the same code into Swift.

 var myCell = tableView.cellForRowAtIndexPath(indexPath) as! MPSurveyTableViewCell myCell.customLabel.textColor = UIColor.redColor()

Since UITableView reuses cells, you need to check if the cells are selected and adjust the color accordingly in cellForRowAtIndexPath. There may be typos, but this is the full answer:

 func tableView(tableView: UICollectionView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCellWithIdentifier("cellIdentifierHere", forIndexPath: indexPath) as! MPSurveyTableViewCell // setup your cell normally // then adjust the color for cells since they will be reused if cell.selected { cell.customLabel.textColor = UIColor.redColor() } else { // change color back to whatever it was cell.customLabel.textColor = UIColor.blackColor() } return cell } func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath){ let cell = tableView.cellForRowAtIndexPath(indexPath) as! MPSurveyTableViewCell cell.customLabel.textColor = UIColor.redColor() tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.None) } func tableView(tableView: UICollectionView, didDeselectItemAtIndexPath indexPath: NSIndexPath) { let cell = tableView.cellForRowAtIndexPath(indexPath) as! MPSurveyTableViewCell // change color back to whatever it was cell.customLabel.textColor = UIColor.blackColor() tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.None) } 

Answer 3

Try it,

 func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { tableView.deselectRowAtIndexPath(indexPath, animated: true) var Cell = tableView.cellForRowAtIndexPath(indexPath) as! MPSurveyTableViewCell Cell. customLabel.textColor = UIColor. redColor() } 

Answer 4

swift 3 xcode 8

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { tableView.deselectRow(at: indexPath, animated: true) let Cell = tableView.cellForRow(at: indexPath) Cell?.textLabel?.textColor = UIColor.red } 

Answer 5

Why not use setSelected in a subclass of UITableViewCell?

 override func setSelected(_ selected: Bool, animated: Bool) { super.setSelected(selected, animated: animated) customLabel.textColor = selected ? UIColor.red : UIColor.black } 

or if you want it to return to the highlighted color after a certain time:

 override func setSelected(_ selected: Bool, animated: Bool) { super.setSelected(selected, animated: animated) if selected { customLabel.textColor = UIColor.red DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 0.2, execute: { [weak self] in self?.customLabel.textColor = UIColor.black } } } 

Then just set your cell selection Style = .none
