I am new to iPhone. My application connects to Facebook using the iPhone SDK, and I can post a default message using
@\"http://www.facebook.com/connec
the error message you are getting is due to NSString. this is not an facebook error.
In order to post a message on facebook use the following code
[NSString stringwithFormat:@"http://www.facebook.com/connect/prompt_feed.php/?message=%@",twittermessage];
Then use this string as a reference for the URL to post a message
