08/01/2017 - This project is no longer actively maintained. It will remain here so it can still be used but there will be no further updates or bug fixes. It likely needs a new major version for the recent changes in RN 0.40. If another user wants to consider taking ownership of the repo then please contact me


React Native module bridge to iOS MFMessageComposeViewController

RN >= 0.40 Please use 1.0.0 of this library or higher

RN < 0.40.0 Please use 0.1.0 of this library


composeMessageWithArgs(args, callback)

This method launches a MFMessageComposeViewController and populates any values supplied from the args object.


The args object is required and lets you prepopulate the MFMessageComposeViewController for the user. You can use the following parameters:

recipients - an array of strings
subject - string
messageText - string
attachments - an array of objects
presentAnimated - boolean (animate the appearance of the message composer - true by default)
dismissAnimated - boolean (animate the closing of the message composer - true by default)

attachments array:

      url: 'http://...',               // required
      typeIdentifier: 'public.jpeg',   // required
      filename: 'pic.jpg',             // optional

The url can be a web url to an image, video etc but be careful as by default http urls will not work without making changes to the info.plist in the native project. The url can also be a file path on the device, you could for example use to retrieve info on photos stored on the device.

For typeIdentifier see

For further info on attachments view

The following shows an example args object

		'0123456789', '059847362', '345123987'
	'messageText':'Sample message text',
	'dismissAnimated': false

All the args parameters are optional. Simply omit any parameter not required from the args object. If you don't want to supply any initial data then set the args object to be empty (e.g. {}).

Messages will be sent as SMS or iMessage (depending on support of recipients phone), unless subject is supplied, in which case they will be sent as MMS or iMessage (depending on support of recipients phone, and user having turned on support for Subject on their iOS device).


The callback is required and will return one of four values, letting you know the message sending status. These are accessed via the following class constants:

var Composer = require('NativeModules').RNMessageComposer;

Composer.Sent - the user clicked send and the message has been sent (this does not guarantee delivery, merely that the message sent successfully)
Composer.Failed - the message failed to send for some reason
Composer.Cancelled - user closed the MFMessageComposeViewController by clicking the cancel button
Composer.NotSupported - device does not support sending messages


This method returns a boolean value as a callback indicating whether or not the device supports messaging. This allows you to determine whether or not messaging will work before actually attempting to open a message, and whether you should show/hide certain UI components because of this.

Getting Started


  1. From inside your project run npm install react-native-message-composer --save
  2. In XCode, in the project navigator, right click LibrariesAdd Files to [your project's name]
  3. Go to node_modulesreact-native-message-composer and add RNMessageComposer.xcodeproj
  4. In XCode, in the project navigator, select your project. Add libRNMessageComposer.a to your project's Build PhasesLink Binary With Libraries
  5. Click RNMessageComposer.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Header Search Paths and make sure it contains both $(SRCROOT)/../react-native/React and $(SRCROOT)/../../React - mark both as recursive.
  6. Set up the project to run on your device (iOS simulator does not support sending messages)
  7. Run your project (Cmd+R)

rnpm (react-native link)

  1. From inside your project run npm install react-native-message-composer --save
  2. run react-native link

Usage Example

import React from 'react';
import Composer from 'react-native-message-composer';

// old way of accessing module is still supported too although no longer recommended
// import { NativeModules } from 'react-native';
// const Composer = NativeModules.RNMessageComposer;

Composer.messagingSupported(supported => {
	// do something like change the view based on whether or not messaging is supported
	// for example you could use this in componentWill/DidMount and show/hide components based on result
	// you could also use this to set state within app which would make showing/hiding components easier

// inside your code where you would like to send a message
	    'messageText':'My sample message body text',
	    'subject':'My Sample Subject',
	    'recipients':['0987654321', '0123456789'],
		'presentAnimated': true,
		'dismissAnimated': false
	(result) => {
		switch(result) {
			case Composer.Sent:
				console.log('the message has been sent');
			case Composer.Cancelled:
				console.log('user cancelled sending the message');
			case Composer.Failed:
				console.log('failed to send the message');
			case Composer.NotSupported:
				console.log('this device does not support sending texts');
				console.log('something unexpected happened');


  • Add support for message attachments
  • Fix issue with a second MFMessageComposeViewController seeming to be present if rotate device whilst MFMessageComposeViewController is open
  • Look at implementing MFMessageComposeViewControllerTextMessageAvailabilityDidChangeNotification to listen for changes to the MFMessageComposeViewController canSendText class method


Thanks to Kyle Mathews for the idea.
