//当影片播放完毕或者用户在影片播放时单击Done按钮时,调用moviePlayerDidFinish方法,并传递了一个MPMoviePlayerController类型的对象,它是MPMoviePlayerViewController类的一个属性,MPMoviePlayerController是自动被创建的,用于接受命令但我们不能修改它,可以使用它来管理和配置影片的播放。
//在moviePlayerDidFinish方法中获取到MPMoviePlayerController对象,然后移去NSNotificationCenter的消息通知,停止影片的播放,移去影片播放视图,并释放MPMoviePlayerViewController对象。
