I would like to post updates to Facebook from my iPhone application. I know that there is a Facebook Connect project, but it requires displaying dialogs for entering user's credentials, dialog for posting content, etc. I would like to be able to get the credentials from application settings and post whatever the user put into UITextView.
Is it possible? or am I stack with Facebook Connect?
Thanks!
You need to use Facebook Connect to authenticate and let the user set privacy settings for your app on their profile. You might technically be able to write all the authentication code yourself (see Facebook's Developers page about authentication) but why bother when the experts have done it for you?
You can then use the Facebook Connect API to do whatever you need to do with Facebook, assuming the user has give your app permission to do so.

I there anyway to log users to facebook and google gmail, from another domain site?
Or are there specific API to do that?
I'm not talking about fb login or connect or google login API, i'm talking about "triggering" login forms in some whay or launch requests to sites to login in users.
I would like to make users able to log to facebook from another site, setting up cookies, so when he will return to facebook he will be logged, and viceversa.
And if is there, is it legal or not?
Thanks
Thats not possible, since Facebook are the ones that issue the cookies, I think it might be possible to generate a cookie that will log you into Facebook, but it would be illegal. Swift
I am working on a mac application which involves Facebook support so that they can share to Facebook via our app.
For this, I am using Facebook Graph API's which internally uses oAuth protocol to access user resources. In this process, it uses webview to enter users credentials(username and password) which provides the "Access_token".
But my requirement of the application is that it should not use webview to enter user credentials rather it should use other view controller to provide user credentials. So I need to go for xAuth protocol as in twitter uses.
Can anyone help me in this issue? If facebook supports xAuth, please make suggestions.
Facebook doesn't offer "desktop" application authentication support as detailed here: https://developers.facebook.com/docs/authentication/
What you would have to do, is get them to authorize your app on a website, then use the access token for the desktop app and that is if your app is connected to some kind of server.
Otherwise you will have to follow their suggestion of embedding a browser and reading the access token once it is received.
How do I make an app that doesn't ask for permission when you load it?
Or is that impossible? The only thing the application does is post to the user's wall, but can't I authenticate for that after they load the application?
You can, not sure why others are so positive that it is not possible.
On your server side you can check through facebook api if current user granted you required permission. If not, pass some flag to your fbml where you can display permission prompt link:
Would you like to <fb:prompt-permission perms="publish_stream">allow us</fb:prompt-permission> to post on your wall?
You are not obligated to require users to authorize your app either (but you need authorization before checking for granted permissions or retreiving any user information), you can still allow users to use your app. In fact allowing users to use an app without authorization is even encouraged by facebook recommendations. For optional authorization you can put such fbml on your page:
<fb:if-is-app-user>
<fb:else><a href="http://www.facebook.com/login.php?api_key=...&v=1.0>Would you like to authorize this app?</fb:else>
</fb:if-is-app-user>
If you want to post to their wall via a prompt instead of requiring prior authorization, you should use the connect library. Then you can use some javascript to open the dialog.
In fact, another SO question gives you exactly what you need.

To publish content to users' walls, you need to have the steam_publish permission from them first.
I'm trying to make an application that can connecto to facebook. I've found Facebook Connect for iPhone and I don't like the login form that it has.
Is there any way to make a custom login form? Is there some api functions to call to login an user on Facebook?
Thank you.
I would recommend not going this route. I'd be suspicious of any app that's asking for credentials that's not using the de-facto standard login control. If there is no standard control, then I have to take my chances with whatever the app presents, but in the case of Facebook, the standard control is part of Facebook Connect.
Just use one of the other API's such as the REST API and then create your own UI to capture the login credentials and call the REST API to login.
I want to implement a "remember me" feature on me website using the facebook connect.
On my website, i have the possibility to do the login by two distinct ways:
Normal login
Facebook Connect
When an user performs the login with facebook connect, even if he logs out on his facebook account, i want to keep him logged in on my website. He will only log out if he clicks on the logout button on the website.
Is there a way to do this?
Thanks in advance
Here is a tutorial using PHP that demostrates how to use Facebook connect. If you read the section about the login page, you'll see that Facebook does some funky javascripting that creates session cookies on your domain based on the login status on Facebook. You might be able to manipulate the API to give yourself the persistance that you're looking for.
Good luck, and hope this helps some in your project.
