Question

I used the old rest api for showing the Permission Dialog in Facebook before.
Now, with the new graph API, what can I do? (I’m in IFrame Apps).

I know that I can cheat and popup the permission in a seperate window:

FB.login(function(response) {
                  if (response.session) {
                    if (response.perms) {
                      // user is logged in and granted some permissions.
                      // perms is a comma separated list of granted permissions
                    } else {
                      // user is logged in, but did not grant any permissions
                    }
                  } else {
                    // user is not logged in
                  }
                }, {perms:'offline_access'});

like that.. call the FB.login again (let say I want people to click on a different button and trigger the extended permisison dialog)

However,it looks ugly,and it doesn’t look like a dialog.

Is there a way to generate the dialog? I try to figure out whether FB.ui can help but there is only little information about that.

In addition, I don’t think the ‘response’ callback ever execute. Neither I click “Don’t allow” or “allow”, won’t trigger any call back. any idea?

hihih..anyone can help me?

Answer 1

Finally. find out the solution from another website.
first. after FB.init( … ); do that:

FB.provide("UIServer.Methods",
    { 'permissions.request' : { size : {width: 575, height: 300}, 
    url: 'connect/uiserver.php',
    transform : FB.UIServer.genericTransform }
    } );

Then, whenever you need to call the permssion dialog, do that:

FB.ui({method: "permissions.request", "perms": 'email,offline_access'}, 
    callBack);

It took me so long to figure out by looking at the FB object and find out there is UIServer with permissions.request then from that, I keep searching and find this solution. and FB.ui talks nothing about it.. and FB.provide is not documented. THANKS facebook.
