+
+Installation in iOS
+***********************
+
+Required packages
+==================
+
+  * GCC 4.x or later
+  * CMake 2.6 or higher
+  * Xcode 4.0 or higher
+
+Getting the cutting-edge OpenCV from SourceForge SVN repository
+-----------------------------------------------------------------
+
+Launch SVN client and checkout either
+
+a. the current OpenCV snapshot from here: https://code.ros.org/svn/opencv/trunk
+
+#. or the latest tested OpenCV snapshot from here: http://code.ros.org/svn/opencv/tags/latest_tested_snapshot
+
+In MacOS it can be done using the following command in Terminal:
+
+.. code-block:: bash
+
+   cd ~/<my_working _directory>
+   svn co https://code.ros.org/svn/opencv/trunk  
+ 
+
+Building OpenCV from source using CMake, using the command line
+================================================================
+
+#. Create a temporary directory, which we denote as <cmake_binary_dir>, where you want to put the generated Makefiles, project files as well the object filees and output binaries
+
+#. Enter the <cmake_binary_dir> and type
+
+   .. code-block:: bash
+     
+      cmake [<some optional parameters>] <path to the OpenCV source directory>
+
+   For example
+
+   .. code-block:: bash
+       
+      cd ~/opencv
+      cd ..
+      mkdir release
+      cd release
+      cmake -GXcode -DCMAKE_TOOLCHAIN_FILE=../opencv/ios/cmake/Toolchains/Toolchain-iPhoneOS_Xcode.cmake -DCMAKE_INSTALL_PREFIX=../OpenCV_iPhoneOS -DCMAKE_BUILD_TYPE=RELEASE ../opencv
+
+
+#. Enter the created temporary directory (<cmake_binary_dir>) and proceed with:
+
+   .. code-block:: bash
+      
+      xcodebuild -sdk iphoneos -configuration Release -target ALL_BUILD
+      xcodebuild -sdk iphoneos -configuration Release -target install install
