saveToCameraRoll不是函数

Question

我正在尝试将使用React Native Camera库拍摄的图像发送到Camera Roll。用户按下按钮时，将触发以下功能：  takePicture = async function() {    if (this.camera) {      const options = { quality: 0.5, base64: true }      const data = await this.camera.takePictureAsync(options)      CameraRoll.saveToCameraRoll(data.uri)    }  }我已经知道该应用程序会将图片发送到缓存文件夹，因为执行此代码后，将显示该图片的链接：  takePicture = async function() {    if (this.camera) {      const options = { quality: 0.5, base64: true }      const data = await this.camera.takePictureAsync(options)      console.log(data.uri)    }  }调试器显示以下错误：Possible Unhandled Promise Rejection (id:0)React Native Camera: TypeError: _reactNative.default.saveToCameraRoll is not a functionCam组件的代码：import React, {Component} from 'react';import {StyleSheet, View} from 'react-native'import { RNCamera } from 'react-native-camera'import CameraRoll from 'react-native'import ActionButton from 'react-native-action-button'import Icon from 'react-native-vector-icons/Ionicons'const styles = StyleSheet.create({  container: {    flex: 1,    justifyContent: 'center',    alignItems: 'center'  },  button: {    height: 200,    justifyContent: 'flex-end',    alignItems: 'center'  },  actionButtonIcon: {    fontSize: 20,    height: 22,    color: 'white',  },});export default class Cam extends Component {  constructor() {    super()    this.takePicture = this.takePicture.bind(this)  }  takePicture = async function() {    if (this.camera) {      const options = { quality: 0.5, base64: true }      const data = await this.camera.takePictureAsync(options)      CameraRoll.saveToCameraRoll(data.uri)    }  }  render() {    return (      <View style={styles.container}>        <RNCamera          ref={ref => {this.camera = ref}}          style={{            flex: 1,            width: '100%',            position: 'relative'          }}     

Answer 1

望着这个例子说明如何使用CameraRoll ：

import {

  View,

  Text,

  TouchableHighlight,

  Modal,

  StyleSheet,

  Button,

  CameraRoll,

  Image,

  Dimensions,

  ScrollView,

} from 'react-native'

您必须更换：

import CameraRoll from 'react-native';

经过

import { CameraRoll } from 'react-native';

（我已将其作为答案，因此可以接受并结束问题）

在您的代码中，您可以像这样相互导入：

import React, {

  Component,

} from 'react';

import { 

   RNCamera,

} from 'react-native-camera';

import {

  CameraRoll,

  StyleSheet,

  View,

} from 'react-native';

import ActionButton from 'react-native-action-button';

import Icon from 'react-native-vector-icons/Ionicons';
