我正在使用 Xcode 创建一个 Objective-C、可可、Mac 应用程序。

应用程序循环播放播放列表中的电影。

movie1.mov,
movie2.mov,
movie3.mov,
...
movie1.mov,
movie2.mov,
movie3.mov,
...
and so on

电影是从这样的文件中加载的：

QTMovie* myMovie = [QTMovie movieWithFile:movieFilePath error:&error];
...
QTMovieView *movie_IBView;
...
[movie_IBView setMovie:myMovie];
...
[movie_IBView play:nil]; 
...

这完美！

但是在电影停止播放几个小时后，QTMovieView 仍然非常黑！

应用程序没有崩溃，但 QuickTimeServer 崩溃了，控制台显示以下消息：

谁能帮我解决这个问题，我不知道这是什么'objectForProxy'

谢谢
