Question

Using titanium, does anybody have some simple instructions to get the user’s facebook name, once signed into facebook?

Answer 1

Ah, here is how you do it:

function getFacebookInfo(){
    Titanium.Facebook.requestWithGraphPath('me', {}, 'GET', function(e){
        if (e.success){
            var jsonObject  = JSON.parse(e.result);
            //do something here with these values. They cannot be passed out of this
            //function call... this is an asynchronous call
            //that is, do this:
            saveToDb(jsonObject.first_name);
        } else {
            //some sort of error message here i guess
        }
    });

};

Finally, along with name and username, check out the facebook page for the other variables you can get –

http://developers.facebook.com/docs/reference/api/

FINALLY: be aware that this is a callback, and titanium won’t actually wait for this call to finish. That is, any variable declared to hold the results the returned after the requestWithGraphPAth will immediately return, and as a result almost always be empty.

I guess you could make a nifty loop that just… loops until some variable is set to false. And you’d set the variable to false in the callback… but that seems dodgy.

Just make your call back do everything else, that is, save to the db etc etc

If you do go the route of calling Ti.Facebook.authorise() to log in the user, remember to define

Ti.Facebook.addEventListener('login',function(e){
    if (e.success){ 
...
...
    } else if (e.error){  } else if (e.cancel) { }
}

before the call. And then, in the success bit, you can make a requestWithGraphPath call and so on. I just save all the details to the database and retrieve them each time after that, works fine for me!
