How to move view for value in UISlider in Swift?

I have a UISlider with 50 values. How to move different UIView, when value in slider changes?

I've tried this:

if oldValue < Int(sender.value) {
        viewToMove.center.y = viewToMove.center.y - heightOfDay
        print(viewToMove.center.y)
        oldValue = Int(sender.value)
         print(oldValue)
    } else if oldValue > Int(sender.value) {
        viewToMove.center.y = viewToMove.center.y + heightOfDay
        print(viewToMove.center.y)
        oldValue = Int(sender.value)
        print(oldValue)
    }

Slider's value changing but viewToMove.center.y isn't.

Solution

  • The most probably is the viewToMove layout added with auto layout. If so, then you need to update the constant of the NSLayoutConstraint which holds the centerY position of the viewToMove
