Can Opencv developed in c/cpp - Run in IOS?

I am developing an image processing application in Centos with OpenCV using C/C++ coding. My intension is to have a single development platform for Linux and IOS (IPAD). So if I start the development in a Linux environment with OpenCV installed ( in C/CPP ),Can I use the same code in IOS without going for Objective-C? I don't want to put dual effort for IOS and Linux, so how to achieve this?

See my detailed answer to this question:
iOS:Retrieve rectangle shaped image from the background image

Basically you can keep most of your CPP code portable between platforms if you keep your user interface code separate. On iOS all of the UI should be pure objective-C, while your openCV image processing can be pure C++ (which would be exactly the same on linux). On iOS you would make a thin ObjC++ wrapper class that mediates between Objective-C side and the C++ side. All it really does is translate image formats between them and send data in and out of C++ for processing.

I have a couple of simple examples on github you might want to take a look at: OpenCVSquares and OpenCVStitch. These are based on C++ samples distributed with openCV - you should compare the C++ in those projects with the original samples to see how much altering was required (hint: not much).

It looks like it's possible. Compiling and running C/C++ on iOS is no problem, but you'll need some Objective-C for the UI. When you pay some attention to the layering/abstraction of your modules, you should be able to share most/all core code between the platforms.
