React Native FBSDK

React Native FBSDK is a wrapper around the iOS Facebook SDK, allowing for Facebook integration in React Native apps. Access to native components, from login to sharing, is provided entirely through documented JavaScript modules so you never have to call a single native function directly.

Functionality is provided through three separate npm packages so you never have to include more than you need:

  • react-native-fbsdkcore
  • react-native-fbsdkshare
  • react-native-fbsdklogin

Usage

react-native-fbsdkcore

Graph Requests

var FBSDKCore = require('react-native-fbsdkcore');
var {
  FBSDKGraphRequest,
} = FBSDKCore;

// ...

// Create a graph request asking for friends with a callback to handle the response.
var fetchFriendsRequest = new FBSDKGraphRequest((error, result) => {
  if (error) {
    alert('Error making request.');
  } else {
    // Data from request is in result
  }
}, '/me/friends');
// Start the graph request.
fetchFriendsRequest.start();

// ...

App events

var FBSDKCore = require('react-native-fbsdkcore');
var {
  FBSDKAppEvents,
} = FBSDKCore;

// ...

// Log a $15 purchase.
FBSDKAppEvents.logPurchase(15, 'USD', null, null)

// ...

react-native-fbsdklogin

Login Button

var FBSDKLogin = require('react-native-fbsdklogin');
var {
  FBSDKLoginButton,
} = FBSDKLogin;

var Login = React.createClass({
  render: function() {
    return (
      <View>
        <FBSDKLoginButton
          onLoginFinished={(error, result) => {
            if (error) {
              alert('Error logging in.');
            } else {
              if (result.isCanceled) {
                alert('Login cancelled.');
              } else {
                alert('Logged in.');
              }
            }
          }}
          onLogoutFinished={() => alert('Logged out.')}
          readPermissions={[]}
          publishPermissions={['publish_actions']}/>
      </View>
    );
  }
});

Login Manager

var FBSDKLogin = require('react-native-fbsdklogin');
var {
  FBSDKLoginManager,
} = FBSDKLogin;

// ...

// Attempt a login using the native login dialog asking for default permissions.
FBSDKLoginManager.setLoginBehavior(GlobalStore.getItem('behavior', 'native'));
FBSDKLoginManager.logInWithReadPermissions([], (error, result) => {
  if (error) {
    alert('Error logging in.');
  } else {
    if (result.isCanceled) {
      alert('Login cancelled.');
    } else {
      alert('Logged in.');
    }
  }
});

// ...

react-native-fbsdkshare

Share dialogs

All of the dialogs included are used in a similar way, with differing content types.

var FBSDKShare = require('react-native-fbsdkshare');
var {
  FBSDKShareDialog,
  FBSDKShareLinkContent,
} = FBSDKShare;

// ...

// Build up a shareable link.
var linkContent = new FBSDKShareLinkContent('https://facebook.com', 'Wow, check out this great site!', 'Facebook.com', null);
// Share the link using the native share dialog.
FBSDKShareDialog.show(linkContent, (error, result) => {
  if (!error) {
    if (result.isCancelled) {
      alert('Share canceled.');
    } else {
      alert('Thanks for sharing!');
    }
  } else {
    alert('Error sharing.');
  }
});

// ..

Share API

Your app must have the publish_actions permission approved to share through the share API.

var FBSDKShare = require('react-native-fbsdkshare');
var {
  FBSDKShareAPI,
  FBSDKSharePhoto,
  FBSDKSharePhotoContent,
} = FBSDKShare;

// ...

// Build up a shareable photo, where 'cat.png' is included in the project. A data URI encoding the image can also be passed.
var photo = new FBSDKSharePhoto('cat.png', true);
var photoContent = new FBSDKSharePhotoContent([photo]);
// Share using the share API.
FBSDKShareAPI.share(photoContent, "/me", "Check out this cat!", (error, result) => {
  if (error) {
    alert('Error sharing');
  } else {
    alert('Shared successfully');
  }
});

// ...

Running the Sample App

  • From the Sample folder, run npm install
  • Download and install the Facebook SDK for iOS.
  • Open NHSample.xcodeproj
  • Drag FBSDKCoreKit.framework, FBSDKLoginKit.framework, and FBSDKShareKit.framework from the ~/Documents/FacebookSDK folder into the Frameworks group in the XCode project navigator.
  • Build and run the app to try it out.

Installation

  • Download and install the Facebook SDK for iOS.
  • Follow the getting started guide to link your project with the Facebook SDK frameworks and set up the app delegate.
  • Depending on what functionality you're looking to integrate, run any combination of the following:
    • npm install react-native-fbsdkcore for graph requests, app events, etc. FBSDKCoreKit.framework must be added to the project.
    • npm install react-native-fbsdkshare for share buttons, dialogs, etc. FBSDKCoreKit.framework and FBSDKShareKit.framework must be added to the project.
    • npm install react-native-fbsdklogin for login button and manager. FBSDKCoreKit.framework and FBSDKLoginKit.framework must be added to the project.
  • Open the Xcode project for your app.
  • Drag the folders prefixed with react-native-fbsdk from node_modules into the XCode project navigator.

Troubleshooting

  • If you get a build error stating that one of the Facebook SDK files was not found -- eg. FBSDKCoreKit/FBSDKCoreKit.h -- check two things:
    • Ensure that the Facebook SDK frameworks have been added to the project.
    • Add the folder where the Facebook SDK was to the project's framework search path in Xcode. See Apple's documentation on including frameworks.
