OpenCV UIImageToMat not working in xcode

Question

I wrote some OpenCV code on xcode, but when I compiled, 2 methods got the linker refused: UIImageToMatandMatToUIImage

I used opencv2.framework (from opencv website, version 3.1 for iOS) and it worked fine, then I used cocoapods and integrated opencv 3.1.1 in my project and all the code worked the same, except for these 2 functions that gave me linker. I don’t understand why they do not work, when I delete #include "opencv2/imgcodecs/ios.h", it says that the functions do not exist (instead of the linker failure).

Does anyone know how to fix this? Thanks you
