Может быть, что-то с armv7. Как я могу установить это правильно. Отлично работает на симуляторе

Я столкнулся с этим недавно с версией 3.0.0-RC1 SCANDIT SDK. Для меня проблема заключалась в отсутствии ссылок на libc++.библиотека dylib. (Этапы сборки - > связать двоичный файл с библиотеками)

Вы не устанавливаете связь со стандартной библиотекой C++. Скомпилируйте код как C++ (или Objective-C++, если вам это нужно), и компоновщик автоматически включит эту библиотеку.

Вероятно, это связано с тем, что XCode не использует правильную стандартную библиотеку C++. Чтобы исправить это, нажмите на свой проект, перейдите к целевому объекту проекта в разделе параметры сборки, найдите параметр под названием " стандартная библиотека C++". Установите его либо в libstdc++, либо в компилятор по умолчанию, он не должен быть установлен в libc++.

Это необходимо сделать, поскольку SCANDIT SDK в настоящее время еще не работает с новой стандартной библиотекой C++ 11, которая была недавно введена в XCode. В не столь далеком будущем релизы будет скомпилирован с компилятором C++ 11 и запущен с библиотекой std, установленной по умолчанию в XCode.
