If you want your slider to increment its value on a graduated scale, you'll
have to implement this yourself.
You can use the C library math function 'remainder' for assistance. See man 3
remainder for documentation.
UISlider *slider = ...;
double scaleIncrement = 0.5;
double scaledValue = slider.value - remainder (slider.value,
scaleIncrement);
Or something like that.
