Use the following code

float centerValue = ((iContrastSlider.maximumValue - iContrastSlider.minimumValue) / 2)+iContrastSlider.minimumValue;
[iContrastSlider setValue:centerValue animated:YES];

add this into your slider iContrastSlider.minimumValue = 85/200; iContrastSlider.maximumValue = 200/200;

iContrastSlider.value = 115/200;

This will shows your slider value to center

Use simple math to calculate the average:

float centerValue = ((iContrastSlider.minimumValue + iContrastSlider.maximumValue) / 2) + iContrastSlider.minimumValue;
[iContrastSlider setValue:centerValue animated:YES];
