Changing background color of selected cell?

Question

Does anyone know how to change the background color of a cell using UITableViewCell, for each selected cell? I created this UITableViewCell inside the code for TableView.

Answer 1

In Swift

let v = UIView()
    v.backgroundColor = self.darkerColor(color)
    cell?.selectedBackgroundView = v;

...

func darkerColor( color: UIColor) -> UIColor {
    var h = CGFloat(0)
    var s = CGFloat(0)
    var b = CGFloat(0)
    var a = CGFloat(0)
    let hueObtained = color.getHue(&h, saturation: &s, brightness: &b, alpha: &a)
    if hueObtained {
        return UIColor(hue: h, saturation: s, brightness: b * 0.75, alpha: a)
    }
    return color
}

Answer 2

Works for me

UIView *customColorView = [[UIView alloc] init];
    customColorView.backgroundColor = [UIColor colorWithRed:180/255.0 
                                                      green:138/255.0 
                                                       blue:171/255.0 
                                                      alpha:0.5];
    cell.selectedBackgroundView =  customColorView;

For a solution that works (properly) with UIAppearance for iOS 7 (and higher?) by subclassing UITableViewCell and using its default selectedBackgroundView to set the color, take a look at my answer to a similar question here.

Answer 4

I've had luck with the following:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    bool isSelected = // enter your own code here
    if (isSelected)
    {
        [cell setBackgroundColor:[UIColor colorWithRed:1 green:1 blue:0.75 alpha:1]];
        [cell setAccessibilityTraits:UIAccessibilityTraitSelected];
    }
    else
    {
        [cell setBackgroundColor:[UIColor clearColor]];
        [cell setAccessibilityTraits:0];
    }
}

Swift 5.3

Here I did for a single row without creating a class for the cell.

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    if let cell = tableView.cellForRow(at: indexPath) {
        cell.contentView.backgroundColor = #colorLiteral(red: 0.1411764771, green: 0.3960784376, blue: 0.5647059083, alpha: 1)
    }
}
override func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
    if let cell = tableView.cellForRow(at: indexPath) {
        cell.contentView.backgroundColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
    }
}

Answer 6

I created UIView and set the property of cell selectedBackgroundView:

UIView *v = [[UIView alloc] init];
v.backgroundColor = [UIColor redColor];
cell.selectedBackgroundView = v;
