Answer 1

Using the fbagent, you cannot publish title+description only, you have to also provide a link to an image and a webpage url.
The image can be your iPhone app icon stored on your site and webpage url can be appstore download link of your iPhone app.
This will help popularize and advertise your app.
So, minimum you can do is:
fbAgent.shouldResumeSession = YES;
[fbAgent publishFeedWithName:art
captionText:summ
imageurl:#"http://amanpages.com/wordpress/wp-content/uploads/2009/12/logo2.png"
linkurl:#"http://amanpages.com/"
userMessagePrompt:#"What do i think:"];
Hope it helps.

Answer 2

just check this example:
NSMutableDictionary* params1 = [NSMutableDictionary dictionaryWithObjectsAndKeys:
appId, #"api_key",
#"Happy Holi", #"message",
#"http://www.holifestival.org/holi-festival.html", #"link",
#"http://www.onthegotours.com/blog/wp-content/uploads/2010/08/Holi-Festival.png", #"picture",
#"Wanna Kno abt HOLI.. Check this...", #"name",
#"Wish u 'n' Ur Family, a Colourful day...", #"description",
nil];
[facebook requestWithGraphPath:#"me/feed" andParams:params1 andHttpMethod:#"POST" andDelegate:self];
It will publish to your wall. If you want to publish to friends wall,then replace 'me' with [friend facebook UID].
[facebook requestWithGraphPath:#"1908979/feed" andParams:params1 andHttpMethod:#"POST" andDelegate:self];
