推荐答案

使用 CGImageSource API(例如，CGImageSourceCreateWithURL、CGImageSourceCreateImageAtIndex)将每个图像加载到 CGImageRef.然后使用 CGImageDestination API(例如，CGImageDestinationCreateWithURL、CGImageDestinationAddImage、CGImageDestinationFinalize)将您拥有的许多图像组合到一个图标文件中.CGImageDestinationCreateWithURL 的第三个参数是 kUTTypeAppleICNS.

Use CGImageSource APIs (e.g., CGImageSourceCreateWithURL, CGImageSourceCreateImageAtIndex) to load each image into a CGImageRef. Then use CGImageDestination APIs (e.g., CGImageDestinationCreateWithURL, CGImageDestinationAddImage, CGImageDestinationFinalize) to combine however many images you have into one icon file. The 3rd parameter of CGImageDestinationCreateWithURL would be kUTTypeAppleICNS.
