Summary: Noticed that the minimumValue and maximumValue for the SliderIOS component isn't actually picked up by the native slider that gets rendered. Issue #442 Closes https://github.com/facebook/react-native/pull/583 Github Author: Don Yu <donyu8@gmail.com> Test Plan: Add minimumValue and maximumValue prop to <SliderIOS> component in SliderIOSExample.js for UIExplorer (see screenshots)
