如何知道iOS用户是否拒绝了对react-native的权限？

npm install react-native-permissions --save

import { check, PERMISSIONS, RESULTS } from 'react-native-permissions';

check(PERMISSIONS.IOS.CAMERA)
  .then((result) => {
    switch (result) {
      case RESULTS.UNAVAILABLE:
        console.log('该权限不可用');
        break;
      case RESULTS.DENIED:
        console.log('用户拒绝了该权限');
        break;
      case RESULTS.GRANTED:
        console.log('用户已授予该权限');
        break;
      case RESULTS.BLOCKED:
        console.log('该权限被阻止');
        break;
    }
  })
  .catch((error) => {
    console.log('检查权限时出错：', error);
  });
