CMake 2.8.8 or higher
Xcode 4.2 or higher
Getting the Cutting-edge OpenCV from Git Repository
Launch GIT client and clone OpenCV repository from here

In MacOS it can be done using the following command in Terminal:

cd ~/<my_working _directory>
git clone https://github.com/Itseez/opencv.git
Building OpenCV from Source, using CMake and Command Line
Make symbolic link for Xcode to let OpenCV build scripts find the compiler, header files etc.

cd /
sudo ln -s /Applications/Xcode.app/Contents/Developer Developer
Build OpenCV framework:

cd ~/<my_working_directory>
python opencv/ios/build_framework.py ios
If everything’s fine, a few minutes later you will get ~/<my_working_directory>/ios/opencv2.framework. You can add this framework to your Xcode projects.
