iOS how to make slider stop at discrete points

Question

I would like to make a slider stop at discrete points that represent integers on a timeline. What\'s the best way to do this? I don\'t want any values in between. It woul

Answer 1

What I did for this is first set an "output" variable of the current slider value to an integer (its a float by default). Then set the output number as the current value of the slider:

int output = (int)mySlider.value;
mySlider.value = output;

This will set it to move in increments of 1 integers. To make it move in a specific range of numbers, say for example, in 5s, modify your output value with the following formula. Add this between the first two lines above:

int output = (int)mySlider.value;
int newValue = 5 * floor((output/5)+0.5);
mySlider.value = newValue;

Now your slider "jumps" to multiples of 5 as you move it.
