UITableViewCell Selected Background Color on Multiple Selection - ios

Question

// 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?

Answer 1

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
}

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

Swift 4.2
For multiple selections you need to set the UITableView property allowsMultipleSelection to true.
myTableView.allowsMultipleSelection = true
In case you subclassed the UITableViewCell, you override setSelected(_ selected: Bool, animated: Bool) method in your custom cell class.
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
if selected {
contentView.backgroundColor = UIColor.green
} else {
contentView.backgroundColor = UIColor.blue
}
}

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
}

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()
}

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

Answer 7

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

Answer 8

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.

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
}

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 3/4
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
}
}
}

Answer 12

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
}

Answer 13

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.

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
}
}
