Wie zu Anfang einer Wand mit Facebook Graph API für iPhone schreiben

Question

Ich möchte etwas in der Benutzer Freunde Wand stellen.

Ich benutze dies zu Post in den Benutzer Wand

SBJSON *jsonWriter = [[SBJSON new] autorelease];

    NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                                                           @"Always Running",@"text",@"http://itsti.me/",@"href", nil], nil];

    NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
    NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                                @"a long run", @"name",
                                @"The Facebook Running app", @"caption",
                                @"it is fun", @"description",
                                @"http://itsti.me/", @"href", nil];
    NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"Share on Facebook",  @"user_message_prompt",
                                   actionLinksStr, @"action_links",
                                   attachmentStr, @"attachment",nil];

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

Aber ich brauche, um Post in meinen Freunden Wand. Wie kann ich diese

tun

In diesem Post sie haben erwähnt über targetId muss ich etwas damit zu tun.

Answer 1

Haben Sie versucht, mit,

[facebook requestWithGraphPath:@"[friend_ID]/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

UPDATE:

Posting auf Freunde Wand wird nicht mehr Arbeit mit Grafik-API. Stattdessen müssen Sie FBDialog verwenden.

Answer 2

@mAc

Sie müssen sich zuerst genehmigen facebook. Dann sind Sie ‚FBRequestDelegate‘ Methoden, um Ihre Klasse zu implementieren. Dann machen Sie eine Anfrage mit Grafik-API wie unten angegeben

[facebook requestWithGraphPath:@"/me/friends" andDelegate:self];

Sobald Ihre Anfrage erfolgreich war, api die delegierte Methode 'requestDdidLoad' nennen,

-(void)request:(FBRequest *)request didLoad:(id)result {

    NSLog(@"Result: %@", result);

}

Wir bilden das Ergebnis Sie erhalten die frieds Seite ID erhalten
