我想保存并阅读ICO文件。它没关系，如果它的NSImage或NSBitmapImageRep或任何东西。它只是需要完成。这怎么可能完成？

Answer 1

我为自己找到了。这是我的代码：

NSImage *o = [[NSImage alloc] initWithContentsOfFile:path]; 
CGImageDestinationRef dest = CGImageDestinationCreateWithURL(
                  (CFURLRef)[NSURL fileURLWithPath:newPath], 
                  (CFStringRef)@"com.microsoft.ico", 
                  o.representations.count, 
                  NULL); 
for (NSBitmapImageRep *rep in o.representations) { 
    CGImageRef ref = rep.CGImage; 
    CGImageDestinationAddImage(dest, 
           ref, 
           NULL); 
} 


CGImageDestinationFinalize(dest);
