Swift 2 can not add a slider to a UITableView Cell - ios

Question

I m trying to create a slider cell in a UItableview with swift, it appear, but it's not working, I want to display the value of it in live but it's not working, I tried to use action on the slider itself, I tried changed Editing Changed Method not working too.
Here is my cell code :
import UIKit
class SliderCell: UITableViewCell {
#IBOutlet weak var titleLabel: UILabel!
#IBOutlet weak var maxLegendLabel: UILabel!
#IBOutlet weak var minLegendLabel: UILabel!
#IBOutlet weak var slider: UISlider!
#IBOutlet weak var answerLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
slider.userInteractionEnabled = true
slider.continuous = true
// slider.addTarget(self, action: #selector(sliderValueChanged), forControlEvents: UIControlEvents.ValueChanged)
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
#IBAction func sliderAction(sender: UISlider) {
print("slider ACTION value")
print(sender.value)
}
func sliderValueChanged(sender: UISlider) {
print("slider value")
print(sender.value)
answerLabel.text = "Your choice : " + String(sender.value)
}
func displayBlock(block: Block){
titleLabel.text = block.title
minLegendLabel.text = block.range?.legendMin
maxLegendLabel.text = block.range?.legendMax
slider.minimumValue = Float((block.range?.min)!)!
slider.maximumValue = Float((block.range?.max)!)!
slider.value = 1
}
}
and here is how I declare it in my tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell method :
let cell = tableView.dequeueReusableCellWithIdentifier(CurrentFormTableView.CellIdentifiers.SliderCell, forIndexPath: indexPath) as! SliderCell
cell.displayQuestion(block)
cell.selectionStyle = UITableViewCellSelectionStyle.None
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 160.0
return cell

Answer 1

Add this in Table view cell:
sliderDemo = UISlider(frame:CGRectMake(0, 0, 200,20))
var numberOfSteps : NSInteger = numbers.count - 1
sliderDemo.minimumValue = 6.5
sliderDemo.maximumValue = 4.1
sliderDemo.continuous = true
sliderDemo.value = 4.0
sliderDemo.addTarget(self, action: "sliderValueDidChange:", forControlEvents: .ValueChanged)
self.view.addSubview(sliderDemo)
func sliderValueDidChange(sender:UISlider!)
{
println("number:\(sender.value)")
}

Answer 2

I added the slider to the Storyboard itself and in the code I did this:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! MenuTableViewCell
if indexPath.row == 0 {
cell.slider.alpha = 1
} else {
cell.slider.alpha = 0
}
return cell
}
It means that it will show the slider only on the first cell, and every other cell won't show it.
