라이브러리 Afnetworking 멀티 파트에서 비디오 업로드

갤러리에서 동영상을 업로드하여 서버 멀티 파트로 보내야합니다.

갤러리에서 영화를 선택하면 다음 정보가 있습니다.

 self.videoDictionary = {
    UIImagePickerControllerMediaType = "public.movie";
    UIImagePickerControllerMediaURL = "file:///Users/alin/Library/Application%20Support/iPhone%20Simulator/7.0.3/Applications/714D0B71-80EA-4B6C-9ACF-A287C8F40121/tmp/trim.FF287468-B25E-4EEA-8EAB-A485842476FA.MOV";
    UIImagePickerControllerReferenceURL = "assets-library://asset/asset.MOV?id=393E740F-B7F4-46DA-BB09-69AB92C34660&ext=MOV";
}
