react-native – React Native将图像保存到iOS相机胶卷

static saveImageWithTag(tag,successCallback,errorCallback)

帮助您将图像保存到相机胶卷/图库.

1.首先,确保您的/node_modules/react-native/Libraries/CameraRoll/RCTCameraRoll.xcodeproj已正确链接到您当前的项目.如果没有,您应该首先按照此处的官方文档进行操作. (https://facebook.github.io/react-native/docs/linking-libraries-ios.html#content)

2.第二,准备好你的图像源.对我来说,我把它放在项目资产库中.

3.像这样编码.在这种情况下,我在componentDidMount执行时保存我的图像.

'use strict';

var React = require('react-native');

var {
  CameraRoll,View,} = React;

var CameraRollTest = React.createClass({
  
  componentDidMount() {
    CameraRoll.saveImageWithTag('YOUR_IMAGE_TAG/URI',function(data) {
      console.log(data);
    },function(err) {
      console.log(err);
    });

  },render: function() {
    return (
      <View>
      </View>
    );
  }
});

module.exports = CameraRollTest;
