老是报错呀，编译就不通过，怎么办？

MediaPlayer.framework 已经引入了，就是编译不通过。想了一个下午了

ld: warning: ignoring file /Users/user/自己的程序/MoviePlayer/MediaPlayer.framework/MediaPlayer, file was built for unsupported file format which is not the architecture being linked (i386)

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？
