Change text color in tableview cell in didHighlightRowAt - ios

Question

I have this code:
func tableView(_ tableView: UITableView, didHighlightRowAt indexPath: IndexPath) {
let cell = tableView.cellForRow(at: indexPath)
cell!.contentView.backgroundColor = .blue
cell?.textLabel?.textColor = UIColor.white
var cell2 = tableView.cellForRow(at: indexPath) as! DataTableViewCell
cell2.textLabel.textColor = UIColor.white
}
The background change works fine, but the text color change does not work.
Does anyone know why and how to fix this problem?

Answer 1

I think instead of writing these two lines:
cell!.textLabel?.textColor = #colorLiteral(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
cell?.textLabel?.textColor = UIColor.white
writing only a single line as:
cell.textLabel?.highlightedTextColor = .black
will work fine for you!

Answer 2

Use this function in your DataTableViewCell
func setHighlighted(_ highlighted: Bool,
animated: Bool)
See Apple Developer Documentation

Answer 3

Try any one of these:
// set highlighted color in `tableView cellForRowAt indexPath`
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
cell?.textLabel?.highlightedTextColor = UIColor.white
}
or try this
class CustomCell: UITableViewCell {
// As an alternate of `tableView cellForRowAt indexPath`, label text highlighted color can be set in both these methods of cell - `awakeFromNib` and `prepareForReuse`
override func awakeFromNib() {
super.awakeFromNib()
self.textLabel?.highlightedTextColor = UIColor.white
}
override func prepareForReuse() {
super.prepareForReuse()
self.textLabel?.highlightedTextColor = UIColor.white
}
// or textColor can be directly set here
override func setHighlighted(_ highlighted: Bool, animated: Bool) {
super.setHighlighted(highlighted, animated: animated)
self.textLabel?.textColor = UIColor.white
}
}

Answer 4

The tableView(_:didHighlightRowAt:) function is part of the Controller domain of your app while setting colors is part of the View domain (as per Model—View—Controller pattern). To keep up a good separation of responsibilities you might want to consider changing colors outside of the controller, i. e. in the cell itself. For this to work, you would create a simple UITableViewCell subclass, like so:
class MyCell: UITableViewCell {
class var reuseIdentifier: String { return "MyCell" }
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
if selected {
textLabel?.textColor = UIColor.white
} else {
textLabel?.textColor = UIColor.black
}
}
}
This way the cell itself (instead of the controller) handles its own graphical representation which is the recommended way.

Answer 5

cell.textLabel.highlightedTextColor = [UIColor greencolor];

Answer 6

OK, this code works:
override func awakeFromNib () {
         super.awakeFromNib ()
         // Initialization code
         self.titleCell? .xtxtColor = UIColor.black
         self.titleCell? .highlightedTextColor = UIColor.white
  }
     override func setSelected (_ selected: Bool, animated: Bool) {
         super.setSelected (selected, animated: animated)
         // Configure the view for the selected state
     }
    
    
     override func prepareForReuse () {
         super.prepareForReuse ()
         self.titleCell? .highlightedTextColor = UIColor.white
     }
Thank you very much for your help :)
