Develop a Mac Application

I am currently working on my graduation project. It is going to be an iOS application with deaf people as main target users. I developing it using objective-c alongside OpenCV , which I found very few resources [login to view URL] matches a sign taken from camera with already existing image (of signs) , because I have short time in my hand I will limit the sign image with 5-10 and I intending to use simple matching technique such as matchTemp. to be clear I am not looking for someone to develop the app for me rather someone to consult.I really need any help you could offer.
