/**
 * We'll start by making a window with a button...
 */
var win = Ti.UI.createWindow({ backgroundColor: '#fff' });
var shareButton = Ti.UI.createButton({
    width: 90, bottom: 10, height: 30,
    title: 'Tweet "Hello, World!"'
});
win.add(shareButton);
win.open();

/**
 * Now we include our JavaScript module. There's more info here on how this works: http://appc.me/jsmodules
 */
var social = require('social');
var twitter = social.create({
    site: 'Twitter', // <-- this example is for Twitter. I'll expand this to other sites in the future.
    consumerKey: '9U7332KAWsGzdIZDNpWkw', // <--- you'll want to replace this
    consumerSecret: 'zG0SgCPfxFcwPyVatmYik9tUXMwcMQaKZjj2wOqQeag' // <--- and this with your own keys!
});

/**
 * And when the user clicks on the button, share a message with the world!
 * Note that this will show the authorization UI, if necessary.
 */
shareButton.addEventListener('click', function() {
    twitter.share({
        message: 'Hello, world!',
        success: function() {
            alert('Tweeted!');
        },
        error: function(error) {
            alert('Oh no! ' + error);
        }
    });
});

/**
 * Finally, here are some other methods you might want to use:
 */
/*
    twitter.isAuthorized();
    twitter.authorize(function() {
        alert('Authorized!');
    });
    twitter.deauthorize();
*/

In social.js, look for this

var supportedSites = {
twitter: {
accessToken: 'https://api.twitter.com/oauth/access_token',
requestToken: 'https://api.twitter.com/oauth/request_token',
authorize: 'https://api.twitter.com/oauth/authorize?',
update: 'https://api.twitter.com/1/statuses/update.json'
}
};

change to

var supportedSites = {
twitter: {
accessToken: 'https://api.twitter.com/oauth/access_token',
requestToken: 'https://api.twitter.com/oauth/request_token',
authorize: 'https://api.twitter.com/oauth/authorize?',
update: 'https://api.twitter.com/1.1/statuses/update.json'
}
};

Also, make sure your app in twitter has read and write permissions. Regenerate token if needed.

I made these changes but still can't get v1.1. working:

//1.1 instead of 1
update: 'https://api.twitter.com/1.1/statuses/update.json'

//in "send"
message.parameters.push(['oauth_version', "1.0"]);
client.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

The token is retrieved, but a share post is not validated (error 32).

Can anyone confirm they got this script working for 1.1?

can't get this to work... any suggestions?

var supportedSites = {
    twitter: {
        accessToken: 'https://api.twitter.com/oauth/access_token',
        requestToken: 'https://api.twitter.com/oauth/request_token',
        authorize: 'https://api.twitter.com/oauth/authorize?',
        update: 'https://api.twitter.com/1.1/statuses/update.json'
    }
};

should make it work for api 1.1 for posting
