Getting text from image on ios (image processing)

Question

I am thinking of making an application that requires extracting TEXT from an image. I haven't done any thing similar and I don't want to implement the whole stuff on my own. Is there any known library or open source code (supported for ios, objective-C) which can help me in extracting the text from the image. A basic source code will also do (I will try to modify it as per my need).

Kindly let me know if some one has any idea on this.

Thanks, Vikram

Solution

One of the main open source libraries used to do OCR on iOS is a google-sponsored open source project called tesseract.

Here is some info on compiling tesseract for use in iOS apps:

The same guy has a nice sample project on github demonstrating how a simple client might use the compiled library:

Pocket-OCR
