iOS UISlider snapping

[Duke Leto]

Is it possible to set a UISlider to "snap" to certain values other than by checking if the value selected is near and setting the value to that?
I am capable of the code, but I do not want to waste time.

Not to my knowledge. Class ref is here, I guess you could hack thumbRectForBounds to make it look like it's snapping to discrete values, though it's a nasty kludge...

UISlider can effectively snap by putting the right logic into the sliderChanged: method. Here's the code I used to achieve a gender (i.e. Male / Female slider):

		if (slider.value >= 0.5) {
			slider.value = 1.0;
			genderCode = @"F";
		} else {
			slider.value = 0.0;
			genderCode = @"M";
		}
