How do I have my UISlider go from 1-100 in increments of 5?

Add a target like this:

slider.continuous = YES;
[slider addTarget:self
      action:@selector(valueChanged:) 
      forControlEvents:UIControlEventValueChanged];

And in the valueChanged function set the value to the closest value that is divisible by 5.

[slider setValue:((int)((slider.value + 2.5) / 5) * 5) animated:NO];

So if you need any interval other than 5 simply set it like so:

float interval = 5.0f;//set this
[slider setValue:interval*floorf((slider.value/interval)+0.5f) animated:NO];
