I currently have three separate sliders on my viewcontroller.swift
that I would like to all perform the same function, which is to round the slider value to the nearest position. I have already completed the first one, as such:
@IBAction func changePos(_ sender: UISlider) {
slider.value = roundf(slider.value)
}
I have tried many different ways to add the same function to different UISliders by using slider2, changePos2, etc
, but my app either crashes or doesn't perform the function.
How do I make separate UISliders perform the same function within the same viewcontroller?
You can hook all 3 sliders up to the same @IBAction
. Just use the sender
parameter instead of your slider
output in the implementation.
@IBAction func changePos(_ sender: UISlider) {
sender.value = sender.value.rounded()
}
