Increment UISlider by 0.2 in range 0 to 2.0 [duplicate]

Answer 1

In your sliderChanged method, take the value from your slider, round it to the nearest 0.2, then set the value of your slider to this rounded value. This will snap the slider thumb to 0.2 increments.

You can round like this:

float roundedValue = roundf(value / 0.2f) * 0.2f;
