as we can see this video allows users to take a photo of a business card, i have an idea where i would take a photo of some text , and that photo could then be turned into text on th开发者_开发百科e iphone. how would i be able to implement this using the iOS API ?

cheers guys

The camera stuff is all standard-- use the UIImagePickerController for this.

Text recognition (OCR) is not a built in part of the iOS API, though, so that part really isn't trivial. There are multiple open-source projects that can handle this sort of thing if you want to go after them.

Tesseract is an older but possibly viable one. Check out this post which has info on cross compiling it for iOS.
