インポートしたIOS6SDKでXcode4.2を実行しています（古いMacではXCode 4.5を実行できません）。私のアプリは、iOS展開ターゲット4.3、ベースSDK 6.0、およびarmv7のアーキテクチャのみで構成されています。
以前に動作していたアプリを更新して、ユーザーのアドレス帳にアクセスする許可を要求しようとしています。これは、現在iOS 6の要件です（新しいiOS 6機能を使用）。残念ながら、次のAppleMach-Oリンカーエラーが発生します。

私の推測では、XCode 4.2は、アーキテクチャarmv7のiPhoneOS6.0.sdkではなくiPhoneOS5.0.sdkを探しています。ただし、この問題をどこで修正できるかわかりません。他の誰かが以前にこの問題に遭遇したことがありますか？事前に助けてくれてありがとう！
