React Native 图片保存到相册(支持 Android 和 ios)
原理:
IOS用 RN自带的 CameraRoll,
Android 使用 不成功,需要 react-native-fs 和 CameraRoll 配合使用
已经封装成类:
ImageUtil.js
'use strict';import React from 'react';
import {CameraRoll, Platform} from 'react-native';
import ToastUtil from "./ToastUtil";
const RNFS = require('react-native-fs');
let ImageUtil = {
saveImg: (img) => {
if (Platform.OS === 'ios') {
let promise = CameraRoll.saveToCameraRoll(img, 'photo');
promise.then(function (result) {
ToastUtil.showToast('保存成功!地址:\n' + result);
}).catch(function (error) {
ToastUtil.showToast('保存失败!\n' + error);
});
} else {
const RNFS = require('react-native-fs'); //文件处理
const storeLocation = `${RNFS.DocumentDirectoryPath}`;
let pathName = new Date().getTime() + Math.random(1000, 9999) + ".png";
let downloadPath = `${storeLocation}/${pathName}`;
const ret = RNFS.downloadFile({fromUrl: img, toFile: downloadPath});
ret.promise.then(res => {
if (res && res.statusCode === 200) {
var promise = CameraRoll.saveToCameraRoll("file://" + downloadPath);
promise.then(function (result) {
ToastUtil.showToast('保存成功!地址:\n' + result);
}).catch(function (error) {
ToastUtil.showToast('保存失败!\n' + error);
})
}
})
}
},
};
module.exports = ImageUtil;
Android添加权限:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
