show view only when uitableviecell is pressed

I have a UIViewController with a UITableView and an overlaying view. In the didSelectRowAtIndexPath the view is shown but I want it to hide as soon as the user lets go of the screen. So the view is only shown when the users presses a cell and hidden as soon as he lets go. I tried using touchesEnded but I can't get it to work.

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

    self.colorView.hidden = false
    self.colorView.backgroundColor = colors[indexPath.row]

}

Any suggestions?

You can use touchesEnded method on your TableViewCellto detect when user end touch on this cell. Then use delegate to send this event to your viewcontroller Here for example:

YourTableViewCell.swift

    protocol YourTableViewCellDelegate: class {
        func endTouch(indexPath: NSIndexPath)
    }


    class YourTableViewCell: UITableViewCell {
        weak var delegate: YourTableViewCellDelegate?
        var indexPath: NSIndexPath

       // Add Your Other method
        func bind(index: NSIndexPath) {
             self.indexPath = index
        }

        override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
            self.delegate?.endTouch(self.indexPath)
        }
    }

YourViewController.swift

class YourViewController: UIViewController, YourTableViewCellDelegate {

    // Add Your Other method

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        ...
            cell.delegate = self
            cell.bind(indexPath)
    }

    // MARK: - YourTableViewCellDelegate
    func endTouch(indexPath: NSIndexPath) {
        self.colorView.hidden = true
    }
}

You should call colorView.hidden from your touches ended override.

override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {

        self.colorView.hidden = true
}
