// Doesn't work
cell.selectionStyle = .Blue
//Works when the selection is not multiple, if it's multiple with each selection the previous one disappear...
let cellBGView = UIView()
cellBGView.backgroundColor = UIColor(red: 0, green: 0, blue: 200, alpha: 0.4)
cell.selectedBackgroundView = cellBGView
Any answer how to set background color of the cells which are selected?

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 3
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let selectedCell:UITableViewCell = tableView.cellForRow(at: indexPath)!
selectedCell.contentView.backgroundColor = UIColor.darkGray
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
let selectedCell:UITableViewCell = tableView.cellForRow(at: indexPath)!
selectedCell.contentView.backgroundColor = UIColor.clear
}
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
}
Swift 3
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "yourCellIdentifier", for: indexPath)
cell.selectionStyle = .none
return cell
}
Swift 2
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "yourCellIdentifier", for: indexPath)
cell.selectionStyle = .None
return cell
}
UITableViewCell
has an attribute multipleSelectionBackgroundView
.
https://developer.apple.com/documentation/uikit/uitableviewcell/1623226-selectedbackgroundview
Just create an UIView
define the .backgroundColor
of your choice and assign it to your cells .multipleSelectionBackgroundView
attribute.
This worked for me:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
var selectedCell:UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
selectedCell.contentView.backgroundColor = UIColor.redColor()
}
// if tableView is set in attribute inspector with selection to multiple Selection it should work.
// Just set it back in deselect
override func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
var cellToDeSelect:UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
cellToDeSelect.contentView.backgroundColor = colorForCellUnselected
}
//colorForCellUnselected is just a var in my class
For Swift 3,4 and 5 you can do this in two ways.
1) class: UITableViewCell
override func awakeFromNib() {
super.awakeFromNib()
//Costumize cell
selectionStyle = .none
}
or
2) tableView cellForRowAt
cell.selectionStyle = .none
If you want to set selection color for specific cell, check this answer: https://stackoverflow.com/a/56166325/7987502
All the above answers are fine but a bit to complex to my liking. The simplest way to do it is to put some code in the cellForRowAtIndexPath
. That way you never have to worry about changing the color when the cell is deselected.
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
/* this is where the magic happens, create a UIView and set its
backgroundColor to what ever color you like then set the cell's
selectedBackgroundView to your created View */
let backgroundView = UIView()
backgroundView.backgroundColor = YOUR_COLOR_HERE
cell.selectedBackgroundView = backgroundView
return cell
}
You can use standard UITableViewDelegate methods
- (nullable NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath {
EntityTableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
[cell selectMe];
return indexPath;
}
- (nullable NSIndexPath *)tableView:(UITableView *)tableView willDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
EntityTableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
[cell deSelectMe];
return indexPath;
}
in my situation this works, cause we need to select cell, change color, and when user taps 2 times on the selected cell further navigation should be performed.
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()
}
Updated for Swift 3+, thanks @Bogy
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
}
}
SWIFT 3/4
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
}
}
}
