Solution for CustomCell.selectionStyle = .none if you set some else style you saw "mixed" background color with gray or blue.

And don't forget! func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) didn't call when CustomCell.selectionStyle = .none.

extension MenuView: UITableViewDelegate {
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let cellType = menuItems[indexPath.row]
        let selectedCell = tableView.cellForRow(at: indexPath)!
            selectedCell.contentView.backgroundColor = cellType == .none ? .clear : AppDelegate.statusbar?.backgroundColor?.withAlphaComponent(0.15)

        menuItemDidTap?(menuItems[indexPath.row])

        UIView.animate(withDuration: 0.15) {
            selectedCell.contentView.backgroundColor = .clear
        }
    }
}

By adding a custom view with the background color of your own you can have a custom selection style in table view.

let customBGColorView = UIView()
customBGColorView.backgroundColor = UIColor(hexString: "#FFF900")
cellObj.selectedBackgroundView = customBGColorView

Add this 3 line code in cellForRowAt method of TableView. I have used an extension in UIColor to add color with hexcode. Put this extension code at the end of any Class(Outside the class's body).

extension UIColor {    
convenience init(hexString: String) {
    let hex = hexString.trimmingCharacters(in: CharacterSet.alphanumerics.inverted)
    var int = UInt32()
    Scanner(string: hex).scanHexInt32(&int)
    let a, r, g, b: UInt32
    switch hex.characters.count {
    case 3: // RGB (12-bit)
        (a, r, g, b) = (255, (int >> 8) * 17, (int >> 4 & 0xF) * 17, (int & 0xF) * 17)
    case 6: // RGB (24-bit)
        (a, r, g, b) = (255, int >> 16, int >> 8 & 0xFF, int & 0xFF)
    case 8: // ARGB (32-bit)
        (a, r, g, b) = (int >> 24, int >> 16 & 0xFF, int >> 8 & 0xFF, int & 0xFF)
    default:
        (a, r, g, b) = (255, 0, 0, 0)
    }
    self.init(red: CGFloat(r) / 255, green: CGFloat(g) / 255, blue: CGFloat(b) / 255, alpha: CGFloat(a) / 255)
  }
}

Swift 5 - This works for me:

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        let selectedCell:UITableViewCell = tableView.cellForRow(at: indexPath as IndexPath)!
        selectedCell.contentView.backgroundColor = .red
    }



    func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {

        let cellToDeSelect:UITableViewCell = tableView.cellForRow(at: indexPath as IndexPath)!
        cellToDeSelect.contentView.backgroundColor = .clear
    }

You can also set cell's selectionStyle to.none in interface builder. The same solution as @AhmedLotfy provided, only from IB.

Answer 5

Swift 4

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) 
{
    let selectedCell = tableView.cellForRow(at: indexPath)! as! LeftMenuCell
    selectedCell.contentView.backgroundColor = UIColor.blue
}

If you want to unselect the previous cell, also you can use the different logic for this

var tempcheck = 9999
var lastrow = IndexPath()
var lastcolor = UIColor()
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
    if tempcheck == 9999
    {
        tempcheck = 0
        let selectedCell = tableView.cellForRow(at: indexPath)! as! HealthTipsCell
        lastcolor = selectedCell.contentView.backgroundColor!
        selectedCell.contentView.backgroundColor = UIColor.blue
        lastrow = indexPath
    }
    else
    {
        let selectedCelllasttime = tableView.cellForRow(at: lastrow)! as! HealthTipsCell
        selectedCelllasttime.contentView.backgroundColor = lastcolor
        let selectedCell = tableView.cellForRow(at: indexPath)! as! HealthTipsCell
        lastcolor = selectedCell.contentView.backgroundColor!
        selectedCell.contentView.backgroundColor = UIColor.blue
        lastrow = indexPath
    }
}

The problem with Kersnowski's approach is that when the cell is redrawn the changes made when it's selected/deselected will be gone. So I would move the changes into the cell itself, which means subclassing is required here. For example:

class ICComplaintCategoryCell: UITableViewCell {
    @IBOutlet var label_title: UILabel!
    @IBOutlet var label_checkmark: UILabel!

    override func layoutSubviews() {
        super.layoutSubviews()
        reload()
    }
    func reload() {
        if isSelected {
            contentView.backgroundColor = UIColor.red
        }
        else if isHighlighted{
            contentView.backgroundColor = UIColor.red
        }
        else {
            contentView.backgroundColor = UIColor.white
        }
    }
}

And in your table view delegate just call reload:

if let cell = self.table.cellForRowAtIndexPath(path) as? ICComplaintCategoryCell {
    cell.reload()
}
