Use "steps", like this one: http://stackoverflow.com/questions/2519460/uislider-with-increments-of-5 just adapt it to your needs. — Larme, Oct 01 '15 at 07:58

You can round like this:

_ie.text = [NSString stringWithFormat:@"%0.1f",(roundf(_Iel.value * 2.0) * 0.5)];

This will work for 0.5 or any other interval

- (IBAction)sliderValueChanged:(id)sender
{
    self.increment = 0.5f;
    float roundedSliderValue = roundf(self.theSlider.value / self.increment) * self.increment;
    _ie.text = [NSString stringWithFormat:@"%0.1f",roundedSliderValue];
}
