How can I use the facebook connect api for the iphone to to invite friends to an application or send a message

In my iPhone application, I wanted to add the function of signing into Facebook and letting a friend know about the app. I know how to sign in and get the friends list, but I cannot find a good way of inviting a friend. So far, I haven't been able to come up with a way to invite a friend (I don't think one can with t开发者_如何学运维he iphone facebook sdk yet) or send a message to the inbox. Is there a way to do either of these? If not are there any better options I haven't thought of? Thank you for any advice.
