Is there any iphone Class that converts images to text format?

Question

I want to develop an iPhone application that is going to convert some sort of images to text formats. I want to know that is there any built-in library for achieving this pu

Answer 1

I have used tesseract. Its accuracy ranges from 0-100% depending upon various factors like how well the image is captured,fonts and color of the text etc.

But it can give you very good result if you have a very clear image with very clear text.
