Undefined symbols for architecture i386:

      -[ViewController moviePlayerDidFinish:] in ViewController.o
      -[ViewController buttonClicked:] in ViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)错误信息好像是找不到MPMoviePlayerPlaybackDidFinishNotification一样的,可是我的framework真的引入了,好像framework的引入菜单变了,还是我引入的方法不对?
