ios - iOS アプリから開いているグラフに予期しない結果が投稿される。写真以外のすべてのパラメータは Facebook には表示されませんが、Graph API エクスプローラーでは機能します

Question

「5 - オープン グラフ ストーリーの公開」チュートリアルを文字通り実行しましたが、いくつかの問題に直面しています。Graph API Explorer を使用すると、コードはエラーや警告を生成せず、タイムラインに正しく表示されます。スナップショットを表示するには、リンクをクリックしてください ( http://drsolution.com.br/testes/starbuzz/open%20graph.png )。しかし、私のアプリが同じ種類のコードを生成し、グラフを開くと、オブジェクトやアクションではなく、写真のみがアップロードされます。( http://drsolution.com.br/testes/starbuzz/posted%20by%20ios%20app.png )

コードは次のとおりです。

- (IBAction)publicar:(UIButton *)sender {

    if ([FBSession.activeSession.permissions
     indexOfObject:@"publish_actions"] == NSNotFound) {

    [FBSession.activeSession
     reauthorizeWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
     defaultAudience:FBSessionDefaultAudienceFriends
     completionHandler:^(FBSession *session, NSError *error) {
         if (!error) {
             // re-call assuming we now have the permission
             [self publicar:sender];
         }
     }];
    } else {
    if (self.selectedPhoto) {
        [self postPhotoThenOpenGraphAction];
    } else {
        [self postOpenGraphActionWithPhotoURL:nil];
    }
   }

}
