i downloaded hackbook from https://github.com/facebook/facebook-ios-sdk/tree/master/sample/Hackbook (* i am not sure this is the right place to download it), because i wanted to know how to send an invitation to a friend from a iphone native application.

i clicked “send invite”, then on the pop-up page, I selected a friend(another facebook account of mine) and pushed “send” button.
“Sent request successfully.” is displayed on the bottom of the screen.

but I don’t get any request.

who can tell me how to send an invitation, better if there is a sample.
thanks in advance.

    Check if your application is in sandbox mode. Users who are not listed as developers/testers will not receive invites to applications that they do not have the permissions to view.

    UPDATE:

    As the OP has discovered (see comments below) – the problem was to do with not having a Canvas URL set up in the application settings.

    Im not 100% sure why this is ( being an iPhone native application ). Reading through the documentation ( once again :S ) revealed no stated requirement of the Canvas URL. My best guess is that the request needs to be able to be redirected somewhere after it is accepted, if you dont specify the canvas URL maybe somehow you invalidate the request.
    Did all the requests that did not go out appear once you specified the Canvas URL?
