终止引发异常的调用
第一个视频没有删除MPMoviePlayerPlaybackDidFinishNotification通知，因此第二个视频被多次加载。如果您有多个电影播放器，请确保仅在该播放器上注册通知。e、 g:
NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
[center addObserver:self
selector:@selector(moviePlaybackStateChanged:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.movieController];
这至少为我解决了问题。在重新初始化之前，请停止播放器
[播放名称停止] 您好，我没有注册任何通知，但收到了相同的错误（崩溃）。你能帮忙吗？提前谢谢。
