ользую xcode4, в проекте openglES я добавил код для покупки в приложении из учебника:http://www.raywenderlich.com/2797/introduction-to-in-app-purchases

я добавил SystemConfiguration.framework, но эта ошибка происходит:

если я удаляю ссылку структуры, ошибка та же. добавление снова ничего не происходит ... в -Xlinker 2 -framework Foundation -framework UIKit Должен ли я видеть "-framework SystemConfiguration" правильно? почему там нет? у кого-нибудь есть идеи?

вытащить фреймворк из проекта-> фазы сборки-> связать бинарный файл с библиотекой, сделав его первым фреймворком, у которого есть эта ошибка:

SystemConfiguration есть, ошибка все еще там ... что это может быть? Спасибо
