ReactNative：工具类 permissionsManager.js

/**

import React, { Component } from 'react';
import {
    View,
    NativeModules,
    NativeAppEventEmitter,//导入
} from 'react-native';


//在JavaScript中调用Object-C定义的方法，需要先导入NativeModules
//此处的RNCalliOSAction就是我们在iOS上新建的类名
//如果在iOS中设置了导出了类的名字，此处需要和导出的名字一致

/*相机权限*/
const cameraPermission = () => {

   return new Promise((resolve, reject) => {
       manager.cameraPermission().then(data => {
           resolve(data);
       }).catch(err => {
           reject(err);
       });
   });
};

/*相机权限*/
const photoPermission = () => {

    return new Promise((resolve, reject) => {
        manager.photoPermission().then(data => {
            resolve(data);
        }).catch(err => {
            reject(err);
        });
    });
};

/*位置权限*/
const locationPermission = () => {

    return new Promise((resolve, reject) => {
        manager.locationPermission().then(data => {
            resolve(data);
        }).catch(err => {

/*麦克风权限*/

/*通知状态*/

    });

export default {

使用

import PermissionsManager from '../../utils/permissionManager';


 PermissionsManager.cameraPermission().then(data=>{
     this.selectCamera();
 }).catch(err=>{
     Toast.showShortCenter(err.message);
 });
