Question

In my app I have to load a web page in UIWebView where user can login with Facebook. The problem is that when user clicks login, blank page appears.

Is it possible to get back to first page and be logged in?

Web page works perfectly in Safari and opens new window and after login it closes it and gets back to where it left.

EDIT: wrong URL was provided to UIWebView

I think the sample of facebook SDK for iOS does the log in way you want.
Please refer to the link:
facebook-iOS-SDK-sample: https://github.com/facebook/facebook-ios-sdk/tree/master/sample/Hackbook

Especially this part in https://github.com/facebook/facebook-ios-sdk/blob/master/sample/Hackbook/Hackbook/RootViewController.m

/**
 * Show the authorization dialog.
 */
- (void)login {
    HackbookAppDelegate *delegate = (HackbookAppDelegate *)[[UIApplication sharedApplication] delegate];
    if (![[delegate facebook] isSessionValid]) {
        [[delegate facebook] authorize:permissions];
    } else {
        [self showLoggedIn];
    }
}

When you click on log in button, it will open a login dialog, and ask for permission. This is what it looks like: https://developers.facebook.com/docs/mobile/screenshots/ios/#iphone-native

I think the best way to implement the “facebook-related” app is to start with the Hacbook. It is really a nice and detailed sample.
