I am trying to implement some form of snapping or steps with the UISlider. I have written the following code but it does not work as smooth as I hoped for. It works, but when the I slide it upwards it snap 5points to the right leaving the finger not centered over the "slide-circle"
This is my code where self.lastQuestionSliderValue
is a property of the class which I have set to the initial value of the slider.
if (self.questionSlider.value > self.lastQuestionSliderValue) {
self.questionSlider.value += 5.0;
} else {
self.questionSlider.value -= 5.0;
}
self.lastQuestionSliderValue = (int)self.questionSlider.value;

Make sure you hook up the method and the outlet for your UISlider view and you should be good to go.
