React Native Social Share

Use the built-in share view from iOS and Android to let the user share on Facebook and Twitter. It will use the user's existing account without having to get new authorizations. You can even preset text, image and link for the share view.

In other words a React Native wrapper for the SLComposeViewController

Support for Android

27 Feb 2017 - @minhtule has made improvements to sharing on Android

10 Feb 2017 - @Jberlinsky has added support for Android

Let me know how it works.

Animation

Getting started

  1. npm install react-native-social-share --save
  2. react-native link
  3. In XCode, in the project navigator right click LibrariesAdd Files to [your project's name]
  4. Go to node_modulesreact-native-social-share➜ iOS and add KDSocialShare.h and KDSocialShare.m
  5. Go to your project's Build PhasesLink Binary With Libraries phase
  6. Add Social.framework to ➜ Link Binary With Libraries build phase of your project (click the '+' and search for 'social').
  7. Add 'LSApplicationQueriesSchemes' key (Type: Array) with items (Type: String) 'fb' and 'twitter' to Info.plist of your project
  8. Run your project (Cmd+R)

Now you can implement the share popups in your react native code.

Example of implementation

First you should make the native implementation available in the react code by inserting the following line in the top of the file

import {
  shareOnFacebook,
  shareOnTwitter,
} from 'react-native-social-share';

After doing that you will be able to popup the share views from your own functions. I made two examples below, one for Facebook and one for Twitter

  tweet : function() {
 
    shareOnTwitter({
        'text':'Global democratized marketplace for art',
        'link':'https://artboost.com/',
        'imagelink':'https://artboost.com/apple-touch-icon-144x144.png',
        //or use image
        'image': 'artboost-icon',
      },
      (results) => {
        console.log(results);
      }
    );
  },
 
  facebookShare : function() {
 
    shareOnFacebook({
        'text':'Global democratized marketplace for art',
        'link':'https://artboost.com/',
        'imagelink':'https://artboost.com/apple-touch-icon-144x144.png',
        //or use image
        'image': 'artboost-icon',
      },
      (results) => {
        console.log(results);
      }
    );
  },

The two implementations take the following parameters

  • shareOnFacebook(options [object], callback [function])
  • shareOnTwitter(options [object], callback [function])

IMPORTANT Both the options object and the callback function needs to be set. The options object can be empty though if you do not want to preset any of the possible options.

Options

The options object lets you pre-populate the share view for the user. You can use the following parameters:

Parameter Desciption
text Sets the initial text of the message on the SLComposeViewController instance.
imagelink Adds an image file from the given publicly available URL as attachments to the message.
image Adds an image file from the xcode image assets. image takes priority over imagelink. Only one out of two will load.
link Adds a URL to the message. The method automatically handles the URL shortening.

At least the text or link parameter must be specified

Special Case: Facebook on Android

Due to various known problems with Facebook's implementation of Android Intents, sharing with Facebook on Android can only be done in two ways:

  1. If the user has the Facebook application installed, and the text parameter is provided; or
  2. If the link parameter is provided.

Only one of the link or text parameter can be passed to the shareWithFacebook method on Android devices. Image parameters are ignored entirely.

We recommend using the official Facebook SDK to perform more complex sharing operations on Android.

Callback

The callback function runs when the native environment has information for the react environment. Note that some callbacks are only available on iOS due to platform limitations

Callback Desciption iOS Android
"success" Native call made by the viewController - SLComposeViewControllerResultDone – The user sent the composed message by touching the Send button. Yes No
"cancelled" Native call made by the viewController - SLComposeViewControllerResultCancelled – The user cancelled the composition session by touching the Cancel button. Yes No
"not_available" The selected service eg. Facebook, is not available. This can be because the user has not signed in to Facebook on the device or maybe there is no internet access. Yes No (Android functionality falls back to web views)
"missing_link_or_text" Neither the link nor text parameter was provided Yes Yes

You can use these callbacks to present alerts to the user. For example tell the user to login to a certain service.

AppRegistry.registerComponent('ReactNativeSocialShare', () => ReactNativeSocialShare);
