加载QTMovie时发出警告

Question

我刚刚升级到Mountain Lion和Xcode 4.4，现在每当在现有应用程序的QTMovieView上加载电影时，都会收到这些警告。

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.

我正在使用以下代码打开电影：

QTMovie *movie = [QTMovie movieWithURL:url error:nil];

if (movie)
{
    [[movieView movie] stop];
    [movieView setMovie:movie];
}

从NSOpenPanel检索url的NSOpenPanel 。 这部电影开始播放并正常播放，但是我想摆脱这些警告。

我不知道它们来自哪里，它们似乎与NSImage类有关，但是我什至没有在我的应用程序中使用NSImage对象。

来自您的-setMovie调用，而不是您的错。

CompositeToPoint：在SDK 3.26的NSImage.h中声明

- (void)compositeToPoint:(NSPoint)point fromRect:(NSRect)rect operation:(NSCompositingOperation)op fraction:(CGFloat)delta;

我们应该报告错误
