Question

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。

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.

我正在使用此代码打开电影：

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

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

从url检索NSOpenPanel的位置。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，他们与NSImage班级有关，但我甚至没有在我的应用中使用NSImage个对象。

从你的-setMovie调用

，而不是你的错。

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

加载QTMovie时发出警告
