Draw and detect numeric value iPhone, in need of an example without cocoa framework

Question

I want to make an application which detects numeric values drawn by user onto an iphone screen, only numeric values are considered by the application.

For example, suppose in iPhone screen I draw 1 (numeric value). Then it will give me an alert with 1 (numeric value). I am able to draw on iphone screen but enable to detect which number is drawn onto the screen.

Please help me out, I have searched more on google but couldn't found anything... Thanks All in advance.

There may be a solution, but it would cost you (or your client) a licensing fee.

Check out answer # 2 (regarding VisionObjects) to this question.
