此代码 (source
是NSMutableArray
带有NSImage
对象的:
NSURL *fileURL = [NSURL fileURLWithPath:aPath]; CGImageDestinationRef dr = CGImageDestinationCreateWithURL((CFURLRef)fileURL, kUTTypeAppleICNS, 1, NULL); for (NSImage *img in source) { NSLog(@"%@",img); CGImageRef i1 = [img CGImageForProposedRect:NULL context:nil hints:nil]; CGImageDestinationAddImage(dr, i1, NULL); } CGImageDestinationFinalize(dr); CFRelease(dr);
导致以下输出:
2012-12-26 13:48:57.682 Eicon[1131:1b0f] |NSImage 0x1025233b0 Size={11.52, 11.52} Reps=("NSBitmapImageRep 0x10421fc30 Size={11.52, 11.52} ColorSpace=(尚未加载) BPS=8 BPP =(尚未加载)像素=1024x1024 Alpha=NO Planar=NO 格式=(尚未加载)CurrentBacking=nil(故障)CGImageSource=0x104221170”
(...) <- 这里记录了其他 NSImage 实例。
ImageIO:|错误| CGImageDestinationFinalize 图像目的地没有足够的图像
任何想法为什么它以错误结尾?(顺便说一句,我想改用 IconFamily 但它使用的很多方法都已弃用)。
编辑:也许更重要的是提及我用来生成图像的代码,如果该代码有问题(我是菜鸟),我不会感到惊讶:
