のインスタンス化におそらく、クラッシュ...のiOS：アプリケーションは、私が経験してるのクラッシュをデバッグしようとしているため、クラス
私は、Webサーバーからいくつかのデータを取得していますので、私は設定しました私が持っている
子供 ChildConnection ChildParser
ChildConnectionの連絡先、Webサービスやデータを取得し、XMLを解析し、子オブジェクトとして保存ChildParserを、開始します...：三つのクラスそれはプロジェクトで働いています。ここでは、ChildConnectionを持つ代わりに、私は接続を設定します私の現在のプロジェクトで問題となっているのは、デリゲートと関係することです（少なくとも私が思うものです）。エラーが発生してからです： - [AppDelegate children]：認識できないセレクタが送信されました（注：私はこれにかなり新しいです）

申請代理人？それがChildConnectionのインスタンスでない限り、そこに問題があります。 –
私は「やっていることを学んでいる」のですが、投稿されたコードは私の現在のケースで作業しようとしている別のプロジェクトの断片なので、恐らくChildParserクラスを間違って設定しています。代議員と一緒にいないと思います – user969043
あなたの代議員と同じ考えです。あなたのログはクラッシュについて何を伝えていますか、関連する行を投稿できますか？ –
