プロジェクトをARCに変換しようとしていますが、プロジェクトでImageKitを使用しています。ARCリファクタリングツールと私自身の手動リファクタリングはどちらも、私自身のソースファイルからインクルードされたImageKitヘッダーファイルのARCでエラーと警告を生成します。彼らはこのように見えます：

そのとき、プロジェクト設定をターゲット10.6に設定しました。10.7をターゲットにすると、警告が表示されます。

しかし、ARCで10.7だけをターゲットにすると、少なくともプログラムをビルドして実行できます。

何が起きてる？これは正常ですか？それとも、ImageKitはARCと互換性がないだけですか？

<ImageKit / ImageKit.h>を直接インポートしていて、コードにImageKitフレームワークのみがリンクされていたため、Xcode4.2がバーフィングしていたことがわかりました。ARC以外のコードでは問題ありませんでしたが、ARCはそれを好みませんでした。

<Quartz / Quartz.h>（さらにImageKitを含む）のインポートに切り替え、Quartzフレームワーク全体をリンクすることで問題が解決しました。[更新：Quartzフレームワーク全体をリンクする必要はないようです。インポートを<Quartz/Quartz.h>に変更し、ImageKitを直接リンクし続けます。]

それは変だ。
