iPhoneで奇妙な動作をしています。カレンダーイベント(EventKit)を使用するアプリケーションを作成しています。使用するクラスは次のとおりです。

実際には、私の iPhone でログを取得します。
fetch an old-one = (null) 19/12/2012 11:33:09.520 AppCampeggioSingolo [730:8 b1b] create new calendar 19/12/2012 11:33:09.558 AppCampeggioSingolo [730:8 b1b] 保存されたカレンダー EKCalendar
イベントを追加するたびに、彼が追加したiCalカレンダーイベントでそれを見つけることができません。しかし、私の友人の iPhone では、すべてが正しく機能しています。問題がコードに起因しているとは思えませんが、それが何であるかを理解していません。
昨日一日中、今日の一部を Google で検索しましたが、まだ何も見つかりませんでした。
どんな助けでも大歓迎です
編集：電話を忘れました
[CalendarManager addEventForCalendarWithName: @"myCalendar" fromDate:fromDate toDate: toDate withDelegate:self];
デリゲートメソッドでは、このようにイベントのタイトルとメモを設定するだけです
- (void) calendarManagerDidCreateEvent:(EKEvent *) event
{
event.title = @"the title";
event.notes = @"some notes";
}
