Problem

If a user clicks "Don't Allow" when an app asks for additional information, evt.success and hasPermission will still return "true" for this permission, when they should return false. This false positive only occurs in iOS, in my testing.

Sample Code Demonstrating Problem

The following sample code demonstrates the problem.

Use the following steps to reproduce in sample code:
1. Click "Connect with Facebook"
2. Sign in
3. Click "Don't Allow"

/**
* Function that logs the user into Facebook, and makes sure they have
* granted us the "user_checkins" permission.
*/
function checkIfUserIsLoggedIntoFacebook() {
    // if user hasn't logged in yet, don't do anything
    // (they need to click the "Connect with Facebook" button)
    if (Titanium.Facebook.isLoggedIn() === false) {
    }
    // if the user hasn't given us the permissions we want, request them.
    else if (!Titanium.Facebook.hasPermission("user_checkins")) {
        Titanium.Facebook.requestPermission("user_checkins", function (evt) {
            if (evt.success) {
                alert('Permission GRANTED');
            } else {
                alert("Permission DENIED");
            }
        });
    }
    // otherwise, we should be good to go
    else {
        alert('Permission ALREADY GRANTED');
    }
}

/**
* Add a login event listener so we can check if we have all the permissions
* we want.
*/
Titanium.Facebook.addEventListener('login', function (evt) {
    if (evt.success) {
        checkIfUserIsLoggedIntoFacebook();
    }
});

// create our window
var win = Ti.UI.createWindow({ backgroundColor: '#fff' });
win.add(Ti.Facebook.createLoginButton({
    apikey: '645bf1d897d1fa8dc93ed45bc37edc04',
    secret: '49d146f85b8429438262380b85f2ebac',
    style: 'wide'
}));
win.open();
