[TIMOB-12828] iOS: Facebook v3 Module: Login process differs from Ti.Facebook and logout fails

REPRODUCTION: First, run the code below using 3.0.2 GA to see the previous behavior in the iOS simulator. Click login. Notice the dialog box appears. Enter your credentials. Then, click the logout button. Next,

Comment out line 1 and uncomment line 2, so you are using the add-on module.

Change the SDK version to 3.1.0

Add the facebook module and add this item in the tiapp.xml: 495338853813822

Run the code again on the iOS simulator. See results below for findings.

RESULTS: 1. When clicking the login button, the application opens Safari to enter your credentials instead of the dialog as in the previous version. 2. When clicking the logout button, the application throws this error: {noformat} [INFO] :   2013-02-22 13:47:19.369 FacebookTest[87247:22503] *** Assertion failure in -[FBSession close], /Volumes/Datums/CodeValhalla/Github/Mine/titanium_modules/facebook/mobile/ios/Classes/FBConnect/FBSession.m:404 [ERROR] :  Script Error { [TRACE] :  = "#0 () at :0"; [TRACE] :   line = 25; [TRACE] :   message = "FBSession: should only be used from a single thread"; [TRACE] :   sourceId = 275184000; [TRACE] :   sourceURL = "file://localhost/Users/bhatfield/Library/Application%20Support/iPhone%20Simulator/6.0/Applications/DF408B6A-B022-4CB8-B834-A527FD542DD0/FacebookTest.app/app.js"; [TRACE] :  } {noformat} NOTES: With the Facebook.LoginButton, when logging in, the application still opens a Safari window to enter your credentials, but you can logout OK. No error is thrown. On Android, the default login process behaves the same (dialog appears in both cases) and the application can logout OK. FURTHER QUESTION: I don't know if this is a parity issue or not, but when logging out in iOS, you can login again without supplying your credentials. On Android, if you logout, you have to supply your credentials again when you login. TEST CODE:

var fb = Ti.Facebook;
//var fb = require('facebook');
fb.appid = 495338853813822;
fb.permissions = ['publish_stream','create_event'];
fb.addEventListener('login', function(e) {
    if (e.success) {
        alert('Logged In');
    } else if (e.error) {
        alert(e.error);
    } else if (e.cancelled) {
        alert("Canceled");
    }
});
fb.addEventListener('logout', function(e) {
    alert('Logged Out');
});

var login = Ti.UI.createButton({title: 'Login'});
login.addEventListener('click', function(e){
	fb.authorize();
});

var logout = Ti.UI.createButton({title: 'Log Out'});
logout.addEventListener('click', function(e){
	fb.logout();
});

var win = Ti.UI.createWindow({layout: 'vertical', backgroundColor: 'white'});
win.add(login);
win.add(logout);
win.open();
