Ошибки и предупреждения ImageKit при компиляции с ARC

Я пытаюсь преобразовать свой проект в ARC, но я использую ImageKit в своем проекте. И инструмент рефакторинга ARC, и мой собственный рефакторинг вручную выдают ошибки и предупреждения с ARC в заголовочных файлах ImageKit, которые были включены из моих собственных исходных файлов. Они выглядят так:

Именно тогда я установил настройки своего проекта на 10.6. При таргетинге на 10.7 я просто получаю предупреждения:

Но я могу, по крайней мере, собрать и запустить свою программу, если нацеливаться на 10,7 с помощью ARC.

Что здесь происходит? Это нормально? Или ImageKit просто не совместим с ARC?

Оказывается, что Xcode 4.2 был бредом, потому что я импортировал напрямую, и в моем коде была привязана только платформа ImageKit. Это было хорошо для не-ARC кода, но ARC это не понравилось.

Переключение на импорт (который также включает ImageKit) и связывание всей платформы Quartz решило проблему. [ОБНОВЛЕНИЕ: Похоже, вам не нужно связывать всю платформу Quartz. Измените импорт на и продолжайте просто связывать ImageKit напрямую.]

Это странно.
