You can do something like this:

Facebook* facebook = 
   [[Facebook alloc] initWithAppId:@"YOUR_FACEBOOK_APP_ID" andDelegate:self];

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                       @"My Title", @"title",
                                       @"Come check out my app.",  @"message",
                                       @"FACEBOOK_USER_ID", @"to",
                                       nil]; 

[facebook dialog:@"apprequests" andParams:params andDelegate:self];
