Set the UiSlider interval to 0.5

Question

I have a UISlider with minimumValue 0 and maximumValue. I want to make an interval of 0.5 and display it in a label (it's working).

How can I set the interval of my slider? I tried solution to round the value... but I failed.

Thank you

Answer 1

when i do something like that i take an approach like the following:

 #define kSTEPFRACTION .5

 SliderMin = 0
 sliderMax = 20

and get the value withs something like that

 value = slider.value*kSTEPFRACTION;

this will give you values between 0 and 10 in steps of 0.5

Answer 2

float RoundValue(UISlider * slider) {
  return roundf(slider.value * 2.0) * 0.5;
}
