Outside this book, there is not much documentation or support on how to integrate OpenCV 3 into iOS projects. However, if you seek answers about OpenCV 3 in general or iOS in general, you will find a bigger community and a wealth of documentation. Consult the following sites:
The official OpenCV documentation is available at http://docs.opencv.org. This includes tutorials as well as API docs.
OpenCV Answers, the official Q&A site, is available at http://www.answers.opencv.org.
Go to OpenCV's GitHub page at https://github.com/Itseez/opencv to find the latest source code, report issues, or contribute your own revisions. Similarly, see the extra modules' GitHub page at https://github.com/Itseez/opencv_contrib.
The iOS Developer Library, including official documentation on Xcode and all the frameworks in the iOS SDK, is available at https://developer.apple.com/library/ios.
The official iOS Developer Forum is located at https://devforums.apple.com/community/ios.
StackOverflow (https://stackoverflow.com) is a Q&A community that includes many iOS developers and a few OpenCV developers.
My website, http://nummist.com/opencv, is a good place to check for FAQ, errata, and updates pertaining to my books. Also check my GitHub repository for this book at https://github.com/JoeHowse/iOSWithOpenCV. Finally, feel free to e-mail me at
