Linker не может найти _objc_msgSend и многие другие символы

Итак, у меня две проблемы с Xcode. Я новичок в разработке приложений для iPhone, так что любая помощь будет полезна. Я создаю приложение с mapView, поэтому сначала я сделал все как положено. Декларация, вид загрузил, делегаты и так далее. После этого я подключил свойство к виду карты, и получилось 28 ошибок...На симуляторе все работает, включая карту, но на телефоне все время ломается. И после этого я удалил весь код для просмотра карты, все осталось по-прежнему.

Есть идеи, что это может быть? Как сделать вид карты для iPhone?
