Posting a check-in to FourSquare

Now that we have created the basic module in order to authenticate against FourSquare, we are going to extend it to let the user check-in to a particular location. This works by sending the details of your current place (such as a bar, cinema, park, or museum) along with its latitude and longitude values to the FourSquare servers. From here on, you can tell which of your friends are nearby or make your location and activities public for everyone to see.

How to do it…

Open your fsq_module.js file and extend the existing module so that it has the extra method given here:

FOURSQModule.callMethod = function(method, GETorPOST, params, success, error) {
        //get the login information
        try {

            if (FOURSQModule.xhr == null) {
                FOURSQModule.xhr = Ti.Network.createHTTPClient();
            }
            

            FOURSQModule.xhr.open(GETorPOST, FOURSQModule.API_URL + method + "?oauth_token=" + FOURSQModule.ACCESS_TOKEN);
