В моей функции библиотеки происходит "нераспознанный селектор, отправленный экземпляру"

Question

Существует encrypt.a, который шифрует, и клавиатура.framework, которая использует encrypt.a Если использовать encrypt.a непосредственно в тестовой программе, ошибки не возникнет, если вызовет некоторую функцию, которая использует encrypt.a в keyboard.framework, получит ошибка.
