Accessibility

To help ensure your slider is accessible to as many users as possible, please be sure to review the following recommendations:

-accessibilityLabel

Set an appropriate accessibilityLabel value for your slider. This should reflect what the slider affects.

Swift

slider.accessibilityLabel = "Volume level"

Objective - C

slider.accessibilityLabel = @"Volume level";

Minimum touch size

Sliders currently respect the minimum touch size recomended by the Google Material spec touch areas should be at least 48 points high and 48 wide. The height of the slider is set to 27 points so make sure there is sufficient space so that touches don't affect other elements.
