iphone - アドレス帳から既存の連絡先を削除して vCard 文字列を生成しようとするなど、連絡先を変更した後、アプリがクラッシュする

Question

次の github のコードを使用しています。コードの一部を投稿しているだけです。完全なコードを取得してください。すべての連絡先のバックアップをローカル データベースに取得しようとしているリンク を次に示します。問題なく正常に動作しています。しかし、連絡先を削除するか、新しい連絡先リストを追加すると、アプリが最初の関数で SIGBART でクラッシュします - (id) initWithRecord: (ABRecordRef) aRecord WITH THREAD 1 助けてください!!!!
