How to detect when user finished moving Range slider in Swift

Question

I use this is Range slider in my project. How use it.

I want to detect, when user finished moving Range slider. I tried to use function SliderAction(sender: RangeSlider), but I get each moving points in the slider. I think I need to use this function: func endTrackingWithTouch(touch: UITouch?, withEvent event: UIEvent?), but it is doesn't work. How can I make it?

Answer 1

To detect when user finished moving the range slider you can add a controlevent to your slider , you can add it programatically :

mySlider.addTarget(self, action: "sliderDidEndSliding:", forControlEvents: .UIControlEventTouchUpInside)

then you have to do your logic the recieving methode .

    func sliderDidEndSliding(sender: UISlider) {
}

Answer 2

For swift 3 I used this:

mySlider.addTarget(self, action: #selector(self.sliderDidEndSliding), for: .touchUpInside) 

func sliderDidEndSliding() {
  // process stuff 
}

reading values is done with:

@IBAction func mySlider(_ sender: Any) {

}

Answer 3

based on this example viewcontroller, you should check the value sender.selectedMax value changed should be equal to the one you set in storyboard for that slider view

Answer 4

You need to override endTrackingWithTouch. It'll get called when tracking ends by the underlying machinery, giving you a chance to respond.

Be sure and call the super of this during your version of endTrackingWithTouch so the the parents classes can do their bit.

Swift 4

slider.addTarget(self, action: #selector(sliderDidEndSliding), for: .touchUpInside)

and add

@objc func sliderDidEndSliding(sender: UISlider) {
}
