Question

I’m integrating a Facebook log in in my iOs application using the Facebook SDK. Is there a way to change the view the facebook log in button takes me back to once the user logged in ? Right now it takes me back to the view where the FBLoginView was clicked.

To schematize:

Right now I have: View1 -> FacebookView -> View1

What I want: View1 -> FacebookView -> View2

Sure, when you call openActiveSession… on FBSession, call h handler method in the completionHandler block. Something like this:

[FBSession openActiveSessionWithReadPermissions:permissions
                                          allowLoginUI:YES
                                     completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
                                         [self sessionStateChanged:session state:state error:error]];
                                     }];

in this handler you can do things after facebook returns depending on the status. Something like this:

- (void)sessionStateChanged:(FBSession *)session
                        state:(FBSessionState)state
                        error:(NSError *)error
{
    switch (state) {
        case FBSessionStateOpen:
            // login successful
            // do something - like push to another view controller
            break;
        case FBSessionStateClosed:
        case FBSessionStateClosedLoginFailed:
            // show an error prompt or something
            break;
        default:
            break;
    }
}

Check out the facebook docs and also the examples. A lot of this is lifted directly from their examples.
