How to send a text/link/picture to a friend's (facebook) wall through your app in iOS?

Question

Facebook

In general, such a problem. Through my iOS application, I want to send data (text, picture) to a friend's wall via the Facebook SDK. It is easy to place on your wall, but it does not work on a friend's wall.
Rummaged everything on the Internet (stackoverflow, etc.). Didn't find a working example. Although they write that it is possible. As I understand it, it is no longer possible to do this through the Graph API, but it also does not work through FBWebDialogs. Climbed all https://developers.facebook.com/docs/ios. There is no necessary example and even a mention that this can be done.
Does anyone know if it is possible to do this now or not at all? Better yet, if you throw off a link to a working example. It's the worker. It doesn't matter which way, as long as it works. Because everything I found doesn't work.

Answer 1

I do it through FBWebDialogs, code from a real application:

- (void)postLink:(NSString *)link withDescription:(NSString *)description toFriendsWall:(id <FBGraphUser>)friendUser
{
    if (!self.loggedIn) {
        return;
    }

    NSMutableDictionary *parameters = [NSMutableDictionary dictionary];

    if (link != nil) {
        parameters[@"link"] = link;
    }

    if (description != nil) {
        parameters[@"description"] = description;
    }

    parameters[@"to"] = friendUser.id;

    [FBWebDialogs presentFeedDialogModallyWithSession:self.session
                                           parameters:parameters
                                              handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                                                  if (error != nil) {
                                                      // call error callback
                                                  }
                                                  else {
                                                      // call success callback with resultURL
                                                  }
                                              }];
}

the code from the real application is slightly simplified, since in the original it was all wrapped in ReactiveCocoa, so there are no callback blocks in the method signature.
