Selecting and Deselecting UITableViewCells - Swift

Question

Currently I am able to tap a cell and select it using didSelectRowAtIndexPath. However, I am unable to deselect it when tapped. I wish to toggle these two features.

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {


    var selectedCell = tableView.cellForRowAtIndexPath(indexPath)!
    selectedCell.backgroundColor = UIColor.purpleColor()

    tableView.deselectRowAtIndexPath(indexPath, animated: true)

}

I have a TableView in my View Controller.
The dataSource and delegate are already set up.
Multiple selection is enabled in UIBuilder for the table.

In this code what are you trying to do? You get the currently tapped cell and then set the backgroundColor to purple. What is its purpose and is it working? — chrissukhram, Mar 17 '15 at 01:26
Yes, I get the currently tapped cell and set the background to purple and it is working well. Now, I am trying to tap on that cell again and deselect it to the way it was before I selected it. — JohnJLilley, Mar 17 '15 at 01:28

I could have sworn I tried this before and it didn't work then.

I decided to use two functions..

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    var selectedCell = tableView.cellForRowAtIndexPath(indexPath)!
    selectedCell.backgroundColor = UIColor.purpleColor()        
}

func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
    var deselectedCell = tableView.cellForRowAtIndexPath(indexPath)!
    deselectedCell.backgroundColor = UIColor.clearColor()
}

have you tried to create a simple bool and verify in the next tap. If its true you use the code bellow else you keep it tapped until you tap it again

tableView.deselectRow(at: indexPath, animated: true)

Updated Code Syntax for Swift 3 / 4

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
     let selectedCell = tableView.cellForRow(at: indexPath)
     currentCell.backgroundColor = UIColor.purple
 }

 func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
     let deselectedCell = tableView.cellForRow(at: indexPath)
     currentCell.backgroundColor = UIColor.clear
 }
