title: How to integrate AVCam into iOS project
body: <p>I'm trying to use Apple's AVCam project for my app. But I'm quite confused how to do this. I want to open the camera of AVCam when pressing a button. When I add files of AVCam to my project, there is an error: Apple Mach-O Linker error, checking in build phases, there are errors for two storyboards of AVCam. Since AVCam use storyboard so I don't know how to include it into another app. Please help me find a way to do it, thanks.</p>
  
  <p>P/S: I use .xib instead of storyboard for my own app.</p>
