我刚刚升级到Mountain Lion和Xcode 4.4，现在每当我在现有应用程序的QTMovieView上加载电影时，我都会收到这些警告。加载QTMovie时出现警告
2012-08-09 23:56:16.132 MyApp[3590:303] *** WARNING: -[NSImage compositeToPoint:fromRect:operation:fraction:] is deprecated in MacOSX 10.8 and later. Please use -[NSImage drawAtPoint:fromRect:operation:fraction:] instead.

我使用这个代码打开电影：
QTMovie *movie = [QTMovie movieWithURL:url error:nil];
if (movie)
{
[[movieView movie] stop];
[movieView setMovie:movie];
}
凡url从NSOpenPanel检索。电影打开并播放正常，但我想摆脱这些警告。
我不明白他们来自哪里，他们apear涉及到NSImage类，但我甚至没有在我的应用中使用NSImage对象。
