thanks for your comment, but i already check the certificates and target device and it is not working for me — Praful, Oct 30 '13 at 10:24

This means your library "libtesseract_api.a" is not compiled for armv7. You need library same library compiled with armv7. If you still want to use this library you will have to remove support for armv7 (better you compile library with armv7 as armv7, armv7s are used in most of iOS devices) go to Project -> Build Settings -> remove the architecture armv7 from "valid architectures". And set "Build Active Architecture Only" to Yes as you want to build app for configured architecture
