Upload photo on twitPic and facebook - iphone

Hello I am using Twit Pic in my app.I want to upload selected photo to facebook also ..How could I do this.If I upload then how to know user is logged in at fb?

You could try a framework such as ShareKit to facilitate sharing the image on facebook.
I don't think there is a way to tell if the user is logged in without requesting permission to access her account, perhaps via the Facebook sdk.

Allow non admin users to upload a photo a Facebook Page

I am trying to write a facebook app using Facebook C# sdk 5.1.1. The app should let the users to upload a picture to a Facebook page. I was able to write the app where only the admins of the page are able to upload the picture but not users. Even if the user has liked that page I am not able to do it.
I know its possible because on iPhone or from web site you can visit a page and write something on wall or share a photo. But I am not able to figure out how to do it using Facebook API.
the user of the application needs to grant the publish_stream permissions.
You can then make a call to
https://graph.facebook.com/<page_id>/feed?message=<yourmessage>&picture=<picture_url>&access_token=<access_token>&method=POST.
You can try this first by using the Graph API Explorer
Hope this helps.
