Answer 1

Try this one,
NSMutableDictionary *params = [NSMutableDictionary new];
[params setObject:#"Some text" forKey:#"user_message_prompt"];
[params setObject:#"another text" forKey:#"action_links"];
[params setObject:#"Yet another text" forKey:#"attachment"];
[params setObject:#"SOME FACEBOOK ID" forKey:#"target_id"];
[FBWebDialogs presentFeedDialogModallyWithSession:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
NSLog(#" RESULT : %u",result);
}
];

The first thing you need to do is request publish permissions. I wrote this helper method to do it:
void runBlockWithPublishPermissions(void (^block)(FBSession *))
{
FBSession *session = [FBSession activeSession];
NSString *publishPermission = #"publish_actions";
// If we already have publish permissions, then submit.
if (([session isOpen] && FB_ISSESSIONOPENWITHSTATE(session.state)) &&
[session.permissions containsObject:publishPermission])
{
block(session);
}
// Else request for the permissions, then submit.
else
{
[session requestNewPublishPermissions:#[publishPermission]
defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session, NSError *error) {
if (!error)
{
block(session);
}
else
{
NSLog(#"Failed to request publish permissions: %#", error);
}
}];
}
}
You would then use your code in the following way:
void (^submit)(FBSession *) = ^(FBSession *session){
NSMutableDictionary* params = [NSMutableDictionary dictionary];
[params setObject:#"Some text" forKey:#"user_message_prompt"];
[params setObject:#"another text" forKey:#"action_links"];
[params setObject:#"Yet another text" forKey:#"attachment"];
[params setObject:#"SOME FACEBOOK ID" forKey:#"target_id"];
FBRequest *request = [[FBRequest alloc] initWithSession:session
graphPath:#"https://graph.facebook.com/100000329153640/feed"
parameters:params
HTTPMethod:#"POST"];
[request startWithCompletionHandler:nil];
};
runBlockWithPublishPermissions(submit);
