title: How to know if iOS user declined permission or not on react-native?
body: <p>I have an app that requires camera access. On android side I am asking for permission but on iOS
  side you don't have to request permission because Apple do it for you (from plist). But in that case I don't know if iOS user accepted or rejected the permission request. How can I know user is accepted request or not on iOS device.</p>
  
  <p>If user will decline the permission I will navigate to other screen and if accepted camera will open.</p>
  
  <p>I didn't find any answer on stackoverflow or react-native documentation.</p>
  
  <p>Thanks in advance.</p>
