Cocoapods: linked error when using pods and opencv framewrok

Created on 23 Mar 2015 · 3Comments · Source: CocoaPods/CocoaPods
I am using opencv in my iOS project. It is encounter linked error shows below, it works well if I create a clean project with single view controller. Once I use pods to dependence any lib like AFNetworking, it will build fail with linked error.
The way here is not worked for me
I try to used either this guide or download directly to install opencv, but still failed with same error
Linked error:

although this is an old & unresolved issue, but I came across today. The reason is simple: remember to link
AssetsLibrary.framework, AVFoundation.framework, CoreMedia.framework, CoreVideo.framework
Yours seems missing AVFoundation.framework

I would like to help look into this if you could post a sample project that exhibits this issue. I notice that you mention changing the c++ stdlib didn't resolve this so i'm wondering if there is something else at play that is causing issues.
